CALIFORNIA PROPOSITION 65 WARNING
This product and related accessories contain chemicals known to the State of California to cause cancer, birth defects or other reproductive harm.
Pump Not Operating or in Storage:
If pump is not put into service immediately, it must be properly stored to
prevent damage. Store unit in a dry warm location. Never store unit in the
open even if it is protected with plastic or other covering. The bearing
housing and motor will draw moisture, which may result in pump failure after
being put in operation. While in storage pumps with carbon ceramic seals must
have impellers manually rotated (6 to 12 revolutions) after setting non-
operational for 3 months or longer and prior to electrical start-up. Pumps
with tungsten carbide seals must have impellers manuallyrotated (6 to 12
revolutions) after setting non-operational for 3 weeks or longer and prior to
electrical start-up.
Motors:
Pump unit may be shipped less the motor for customer to supply and mount.
Motor Types:
Pumps can be driven by standard open drip-proof, totally enclosed fan cooled,
totally enclosed hazardous location or drip-proof with encapsulated windings
for moisture protection. If motor is to operate in the open or in a dusty
location a totally enclosed fan cooled motor must be used. If pump is to
operate in a damp location a motor with encapsulated winding should be used.
Motors are to be sized so that no overload will exist in the operating range
of the pump.
NOTE: When pump units are mounted at the factory, the driver and pump are aligned before shipment. During transit and handling of pump and components misalignment may occur. Before operation the drive alignment should be checked.
Shaft Couplings:
We recommend using Wood’s flexible coupling to prevent misalignment and noise
that can be caused by other couplings. The extra cost of the coupling is
easily saved in installation and field service that can result from coupling
problems.
V-belt drive:
Where V-belts are used, keep belts tight by adjusting motor base screws. Belts
should run cool. If belts heat up it will indicate slipping. The V-belts
should be fiddle string tight.
CAUTION: Belt guards and coupling guards must be properly installed before operating pump unit.
Electrical Starting Equipment:
If electrical starting equipment is not furnished with pump, certain
precautions must be observed in selecting motor starter.
Type of Starter:
For three phase power a magnetic starter with 3 leg overload protection is
recommended to prevent motor burnout that can occur from single phasing or
transformer faults on three-phase systems. For single-phase motors a standard
starter with 2-leg overload protection is recommended.
Electrical:
- For motor overload protection the magnetic starter trip amp rating should not be more than 1.25 times the full load amps of the motor. Hydromatic recommends a rating of 1.15 times the full load amps of the motor.
- Always use fused disconnect switch or circuit breaker ahead of magnetic starter for short circuit protection. When duplex pumps are used and are operated from single disconnect switch, be sure disconnect switch is large enough to withstand the starting current of both pumps coming on at once. This can occur after a power failure. This is important as a blown fuse or tripped circuit breaker can make both pumps and an alarm system inoperative, resulting in flooding or other damage.
Ground:
Connect a ground wire to motors, control box and other related controls,
ground wire to be sized to the National Electric Code article 250-95. Ground
wire must be connected to a driven ground stake or to a ground wire from the
supply service. If a ground stake is used it must be driven at least 8 feet
into the ground.
Codes:
All local wiring codes must be observed and any exceptions to data given must
be followed in accordance with the local code. Consult the local inspector
before installation to avoid costly delays that can occur due to rejection
after job is finished
Pump Installation
Pump Installation Foundation:
Pump frame or base should be installed on a concrete floor with proper
shims and grout. Use hardwood tapered shims to drive under base to level. Base
should be about 1 to 1-1/2″ off the floor. Build form around the base and fill
base inside cavity with grout. Foundation bolts can be set in the grout or set
in the concrete floor with expansion bolts. Grout should be made with 1 part
cement and 2 parts sand. Mixture should be fluid enough to run under base.
Wood shim blocks can be removed after grout has set and holes filled with
quick set cement.
NOTE: Maximum 5/8″ diameter fastener is to be used for mounting pump to foundation
All piping to suction and discharge openings of pump must be supported to remove stress from the pump case and bearing frame.
Suction Pipe:
- Suction pipe should be same size as pump opening. DO NOT use larger suction pipe as priming time will be increased and velocity may not be high enough to properly carry solids.
- Pump should be installed as close to the liquid being pumped as possible with a minimum of elbows or fittings.
- To avoid air pockets suction pipe must be as short and direct as possible. Suction pipe must always slope upward to the pump from the source of the liquid being pumped.
- The suction pipe should be installed at a distance equal to 1-1/2 times the diameter of the suction pipe from the wall of the wet well, minimum.
- The suction pipe should be installed at a distance equal to one half the diameter of the suction pipe or 3″ from the floor of the wet well, minimum.
- If more than one suction pipe is to be installed in the same wet well, a distance equal to at least 3 times the diameter of the suction pipe should separate them, minimum.
- Submergence of the suction pipe is critical to efficient pump operations. See the following chart for the recommended minimum submergence vs. velocity. Submergence may be reduced by installing a standard pipe increaser fitting at the end of the suction pipe. The larger opening size will reduce the inlet velocity and required submergence. See Figure 1, page 9.
Vertical Suction Lift:
Vertical lift should not be more than 25 feet. This is for starting level
only. After pump primes, level can be pumped down to 26 to 27 feet if desired,
but sump level must rise up to the original level for restart. All suction
line joints must be airtight as a leak in the suction pipe can cause pump to
lose prime or not prime at all. Always check N.P.S.H. calculations for
available atmosphere pressure before applying pump.
Discharge Lines:
If the discharge line ends at level lower than the liquid being pumped, a
siphon breaker must be installed in the discharge line. Otherwise, siphoning
action may cause damage to the pump. The discharge line should include a
system check valve, with outside weight or spring, to protect the pump from
excessive shock pressure and reverse rotation when pump is stopped. Do not
depend on the check valve at pump suction to hold discharge pressure. The
discharge line should include an isolation valve, plug valve or gate valve, to
isolate the pump from the discharge line. This will allow maintenance to be
performed on the pump or check valve without draining the discharge line.
Air Bleed Pipe:
A 3/4″ or 1″ bleed line with ball valve or gate valve must be installed
between the pump discharge flange and discharge check valve. The bleed line
should be installed as close to the discharge check valve as possible, end of
bleed line to extend a minimum of 6″ below low water offset point in the wet
well. The valve in the bleed line is to be fully open at initial start-up of
pump. After initial start-up the valve is to be left partially open at all
times. This will allow any trapped air or gas to be vented back to the wet
well. Be sure vent line is under water at all times. This is important. See
installation drawings. (Figure 2) Self-priming pumps will not compress air to
any extent. Pump may not prime if the bleed line is not used or closed and may
not reprime if pump loses prime after the discharge line is full of water and
a discharge check valve is used.
Drain Line from Pump Case:
A pipe should be installed in the lower drain tapping of volute case and be
piped back to the wet well. Install a shut-off valve, ball valve or gate valve
in this line. This will permit draining of pump case if necessary to remove
suction cover to clean impeller or perform maintenance on the pump.
Electrical Connections:
Connect power lines to motor from magnetic starter. Turn pump shaft by hand to
be sure it is free before attempting to start motor. Turn power ON and OFF
quickly to check rotation. If motor is three phase, interchanging any two
lines to motor can reverse rotation. If motor is single-phase, consult
literature supplied with the motor for specific instructions. Correct pump
rotation is clockwise when looking at pulley or coupling end (power end) of
pump. Direction arrow is cast on bearing housing.
Priming:
For initial prime, remove check valve cover cap from suction inlet side of
pump casing and fill pump housing with water. Fully open the air bleed valve
in the bleed line. Replace cap, being sure gasket is in place and that seat is
clean. Start motor and allow sufficient timing for priming. Priming time is
dependent on pump speed, impeller diameter and vertical suction lift.
Cleaning Impeller:
If impeller gets clogged at any time, suction cover can be removed by
unscrewing four hand knobs or nuts. Remove suction cover with jacking bolts.
Drain pump case before removing suction cover. Tap on knobs with hammer to
loosen. Be sure O-ring gaskets are in place before replacing suction cover.
Use grease on machined faces to make removal easier at a later date. Tap on
hand knobs with hammer to retighten.
Adjusting Impeller Clearance:
Impeller face vanes must be within .015″ of suction wear plate for most
efficient operation. When wear plate or impeller wears, it can be readjusted
to proper clearance from the outboard bearing end without the use of shims or
disturbing the pump case or piping. Loosen the three screws with the jam nuts.
Tighten the other three screws evenly until the impeller just drags on the
suction wear plate when the shaft is turned by hand. Back off the three screws
and place a .015 shim under the head of the screw. Turn screw up against the
shim, then remove shim. Repeat this operation on each of the three pushing
screws. Now retighten the three screws with jam nuts, pushing the housing up
against the three adjusting screws. Retighten the jam nuts and pump is ready
to operate with the impeller face .015″ from suction wear plate. This
clearance should be checked at least once a year and more often if water-
containing abrasives are being pumped. When impeller face wear exceeds 1/8″,
impeller, wear plate and volute lip plate should be replaced.
WARNING: Before handling these pumps and controls, always disconnect the power first. Do not smoke or use sparkable electric devices or flames in a septic (gaseous) or possible septic area. Be sure all V-belt guards or coupling guards are in place before operating unit.
Pump Maintenance
Pump Maintenance Replacing Impeller and Volute Lip Plate:
Disconnect power from the motor before attempting to work on pump. Drain pump
volute case and oil from seal chamber. Remove suction plate with wear plate
attached. Clean any trash out of pump volute, clean all machined surfaces and
wipe all ports clean. The following describes and pertains only to the new 4″
self-priming pump. Remove stainless steel socket head impeller screw that
locks impeller to the shaft. This screw has a right-hand thread. Remove
impeller lock washer with pin. Block impeller vane with a piece of hardwood
and unscrew impeller by turning pump shaft counterclockwise. Impeller shaft
has a right-hand thread. Use large crescent wrench or strap wrench on shaft,
pulling against the key. A pipe wrench can be used if care is used not to
damage shaft. It may be necessary to tap on impeller vanes with hammer to
break impeller loose, especially if pump has been in service for a long period
of time. The following describes and pertains only to the new 6″ self-priming
pump. Use a taper fit impeller shaft.
If impeller is held to the shaft with a taper fit, remove the stainless steel nut on the end of shaft, then remove washer. A taper fit shaft can be identified by the key that drives the impeller. To remove impeller, loosen 3 holding screws at outboard bearing cap and tighten up on back-off screws. This will pull the impeller loose from the shaft. After impeller is removed, retighten screws to bring bearing cap back to original position. It will be necessary to readjust the impeller clearance after the impeller is reinstalled. See adjusting instructions. After impeller is removed, unscrew 3 or 4 stainless steel socket head screws that hold volute lip plate in place. Tap on plate to loosen and remove through volute case inlet opening. The inboard seal now can be removed for inspection by sliding sleeve from the pump shaft. If the faces are worn, the seal should be replaced. See seal replacement instructions. Clean pump casing thoroughly, removing any rust or dirt from all machined surfaces. Install lip plate with lip in the one o’clock position. Use a pipe compound or NEVER-SEEZ®* on all machined faces. NEVER- SEEZ® is a graphite compound that will not wash away with water and is highly recommended for all repair work for use on machine faces. This compound can be obtained from Hydromatic Pump if not available at local supply houses.
The following pertains to the new 4″ self-priming pump. Use Permatex®* on the
3 stainless steel screws that hold volute lip plate in place. Reinstall the
lip plate and tighten the screws. Install seal on shaft and place seal spring
in place. Block impeller vane with a piece of hardwood and screw impeller on
by turning pump shaft clockwise. Use a large crescent wrench or strap wrench
on shaft, pulling against key to retighten. A pipe wrench can be used if care
is used not to damage shaft. Replace impeller lock washer with pin and
stainless lock screw. The new 6″ self-priming pump uses a taper fit impeller
shaft. Use Permatex on the 4 stainless steel screws that hold volute lip plate
in place. Reinstall the lip plate and tighten the screws. Install seal on
shaft and place seal spring in place, then install key and impeller. Caution
must be taken to be sure impeller is seated on the shaft and not on the key.
Replace impeller lock washer and stainless lock bolt.
Replace suction cover with wear plate attached. Check impeller clearance;
adjust if necessary as described under adjusting instructions. Refill seal
chamber as described under lubricating instructions.
Replacing Inboard Seal:
Use all steps outlined under impeller removal. Slide seal and shaft sleeve
from shaft. It may be necessary to tap on sleeve with plastic hammer to
loosen. After rotating part of seal is removed, use wire hook and pull
stationary seal seat from casting. Wipe seal pocket clean, then install new
stationary seat. Use PB Blaster or equivalent on rubber cap and push in place
with fingers, then wipe the seal face clean. Place new rotating seal part on
sleeve and push sleeve onto shaft. Be sure O-ring gasket is in place in groove
on pump shaft. Reinstall volute lip plate, put seal spring in place and
install impeller. Install impeller washer, impeller lock screw or nut, and
suction cover. Check impeller clearance; adjust if necessary as described
under adjusting instructions. Refill seal chamber with #30 non-detergent
automotive oil.
For RDP Pump Replacing Both Inboard and Outboard Seals:
When it is necessary to replace both seals, which will be indicated by water
leaking from the seal chamber, it is recommended that the complete rotating
assembly be removed so that it can be worked on more easily. Drain pump and
seal chamber as described above. Then loosen or remove the pump coupling or
remove V-belt components, if belt driven. Remove motor bolts and move motor to
one side. Remove bolts in bearing bracket support foot and remove four knock-
off handles from studs in rotating unit housing. Tap on housing with hammer to
loosen, then pull complete assembly from case.
Remove impeller and lip plate; see Replacing Impeller and Lip Plate. Remove inboard seal by sliding sleeve from shaft. Use two screws in tapped holes of seal plate and pry out plate with pinch bar under heads of pull bolts. Remove snap ring from shaft and pull outboard rotating assembly from shaft. Use wire hooks to pull ceramic stationary seal seat from housing. It may be necessary to break the ceramic seal ring. Ceramic ring can be easily broken by tapping with screwdriver. Ring is broken only if worn and needs to be replaced. Wipe housing clean and replace ceramic stationary ring. Use PB Blaster or equivalent on rubber cap to push into housing. Push in stationary seal seat with fingers only, then wipe the seal face clean. Push new rotating seal part onto shaft.
Replace seal spring and holding washer, then install snap ring. Replace seal plate. Be sure O-ring is in place and that flat rubber gasket is in place on backside of seal plate. Use grease on O-ring and push plate into position in seal housing. Replace the 3 socket head stainless steel screws. Use Permatex® on bolt threads. Replace new inboard stationary seal face. Now replace rotating seal part mounted on shaft sleeve. Replace volute lip plate with the 3 or 4 socket head stainless screws. Use Permatex on screw threads. Install seal spring and then screw impeller onto shaft. Lock impeller on with washer and stainless steel socket head screw. If shaft has a taper fit be sure key is in place and in notch of shaft sleeve. Unit is now ready to reinstall in casing. Use NEVER-SEEZ® on machine faces and be sure case O-ring is in place on flange. Replace nuts and bearing bracket support foot. Reset motor and connectcoupling or reinstall belts if unit is belt driven. Refill seal chamber with #30 non-detergent automotive grade oil. Replace top fill plugs.
Replacing Shaft Bearings:
Both bearings are the same size for a given pump. To replace bearings, remove
the impeller, seal plate and seals as described previously. Drain oil from the
bearing oil cavity. Remove holding screws from outboard bearing cap and pull
shaft and bearing assembly from housing. It may be necessary to tap on end of
shaft with plastic or rubber hammer to loosen shaft bearings from housing.
After shaft is removed take snap ring off end bearing cap and push shaft and
bearing from housing.
Use Arbor press to press bearings from shaft. ALWAYS SUPPORT OR PRESS ON INNER
FACE OF BEARING. NEVER PRESS ON OUTER FACE AS THIS CAN DAMAGE THE BEARING. Be
sure housing and all parts are thoroughly cleaned before installing new
bearings. Use care in pushing shaft through lip seals that seal shaft in
bearing housing and bearing cap. After shaft is reassembled, install seals and
impeller and adjust clearance of impellers as described previously.
Pump Lubricating
Pump Bearings Oil Lubricated:
The new 4″ and 6″ self-priming pumps are available only in an oil bath pump
bearing lubrication arrangement. The same care as described in the maintenance
of shaft seal stated above applies to the bearing lubrication. The same basic
instructions apply to lubricating motor bearings, but consult motor
manufacturer’s data on lubricating bearings. Bearings can run quite hot to the
hand without damage to the bearing. Outside temperature of the housing should
not exceed 130˚ F for long bearing life.
Pump Shaft Seals
Shaft Seals:
Hydromatic has introduced a new single shaft seal self-priming pump model and
new dual shaft seal self-priming pump model. The oil cavity is accessible for
filling and draining of the oil cavity from the exterior of the volute casing.
See page 12 for diagram of the 4″ pump and page 14 for a diagram of the 6″
pump. The oil in the seal chamber should be checked every six months or every
three months if water-containing abrasives are being pumped. Remove hex head
plug from top of seal chamber and loosen hex plug at bottom of seal chamber.
Place a container under the lower plug then remove lower plug and allow oil to
drain into container. After all oil is removed, pour used oil into a glass
container so that it can be observed. If the oil is clean it will indicate
seals are in good condition. If a small amount of water shows in the oil, this
will also indicate satisfactory seal operation. If considerable water and some
dirt shows in the oil, it will indicate the inboard seal is worn and should be
replaced before outboard seal is damaged. If seals are in good order, refill
the seal chamber with #30 non-detergent automotive oil. About 2-1/2 quarts are
required. Fill with funnel or tube so that the air can escape. Oil chamber
must have a 1″ air gap; do not overfill oil chamber.
Pump Troubleshooting
WARNING: Before handling these pumps and controls, always disconnect the power first. Do not smoke or use sparkable electrical devices or flames in a septic (gaseous) or possible septic area. Be sure all belt guards and exposed coupling guards are in place before operating unit.
WARNING : If the pump has overheated, allow pump to cool before servicing. Do not remove plates, cover, gauges or fittings from an overheated pump. Liquid inside the pump case can reach the boiling point, and vapor pressure within the pump case may cause parts to be ejected with great force. Drain pump case only after pump has been allowed to cool. Use care to prevent personnel from touching the hot liquid.
Pump will not prime:
- Pump discharge does not have air bleed line installed. See pump installation instructions for air bleed line.
- Vertical suction lift is too high. Vertical lift for priming should not be more than 20 feet.
- Allow sufficient time for priming. On high lifts and at low pump speeds priming time may take 5 minutes or longer.
- Suction line has an air leak. Install a vacuum gauge at pump suction flange and start pump. After a vacuum is established, stop pump and see if gauge holds. If gauge hand drops, it will indicate an air leak at some connection below the gauge tap.
- Check pump rotation. Pump must turn clockwise when looking at the power end of pump.
- Not enough liquid in pump casing. Add water to the case. Pump needs water in the pump case to prime.
- Suction check valve damaged or contaminated. Replace check valve.
- Leaking or worn seal or pump gasket. Check pump case vacuum, replace leaking or worn seals or gaskets.
Pump primed OK initially but occasionally loses prime and will not reprime without adding water:
IMPORTANT : Drain pump case and close discharge gate valve before removing inspection cover.
- Air bleed line is not installed properly as specified or is plugged. See installation instructions.
- Check priming port for plugging. Remove inspection cover on right side of case when facing power end of pump. Check priming port hole in case below inspection plate for plugging.
- Impeller may be worn, leaving too much clearance between impeller face and suction wear plate. Adjust impeller as described under adjusting instructions. If impeller and volute lip plate are worn, they must be replaced to regain original priming efficiency.
Pump makes a loud crackling noise when operating:
- If pump has been operating satisfactorily and this noise suddenly starts, it may indicate that some large object is lodged in the suction check valve, suction cover/plate or impeller causing the pump to be noisy. Remove debris from these areas of the pump.
- If noise exists when suction pipe, check valve and suction cover port are clear, it may indicate too high a capacity being delivered for a given suction lift, causing suction cavitation. If pump is allowed to operate under these conditions, the impeller will be damaged. Using a smaller impeller or reducing the pump speed if a belt drive is used may alleviate the cavitation. Consult factory for recommendations.
- If cracking noise is pronounced when pump is operating at low capacity it may indicate pump is operating too near the shut-off head. Increasing the impeller diameter or increasing pump speed may alleviate this condition. Consult factory for recommendations.
- Performance curves show maximum / minimum capacity that the pump will deliver at a given condition point and the allowable suction lift without cavitation. Use vacuum gauge at pump suction to check total suction lift when pump is operating. Use discharge pressure gauge at pump discharge to check discharge head. Total the two-gauge reading to determine the total dynamic head the pump must operate against.
- Entrained air may be present and is being pumped. Find source of air and eliminate.
- Pump or drive is not securely mounted. Retighten all components.
Pump does not deliver rated capacity:
- Total head may be higher than calculated. Pump capacity is based on total head. Total dynamic head is arrived at by adding the suction gauge reading, in feet, to the discharge gauge reading, in feet. These readings should be taken at the suction flange and at the pump discharge flange connections. Reading should be taken as close to the flange fittings and pump case as possible. To convert psi, pressure per square inch, to feet, multiply the total psi readings by 2.31. This will equal total dynamic head in feet.
- Pump impeller may be worn on the vane faces or the clearance between the impeller and wear plate may be greater than .015″. Adjust impeller to wear plate clearances for proper clearance as described under adjusting instructions. If impeller, suction wear plateand volute lip plate are badly worn they must be replaced.
- Pump speed may be too slow. Check drive assembly, V-beltsor coupling, for slippage.
- Possible air leak in the suction piping. Eliminate the leak
- Suction head may be too high. Reduce lift by raising on/ off levels in the wet well or reduce friction losses due to suction piping arrangement.
- Suction line not submerged at proper levels. Correct suction pipe submergence.
- Blockage in the suction pipe or discharge pipe. Remove blockage. Where the blockage is can be determined by gauge readings.
- Impeller clogged; remove debris
Motor starter overload trips after pump has operated for a short period
- Rags or trash may be caught in the impeller causing extra load. Remove suction cover/plate and clean impeller. Pump shaft must turn freely by hand after cleaning impeller.
- Overload heater may be too small. Check heater size withfull load amps of motor. See an electrical table for proper size.
- Total head may be lower than calculated, causing extra load on the motor. Reducing impeller diameter or reducing speed, if belt driven, will lower motor load. Consult factory for recommendations.
- Pump may be pumping a liquid heavier than water or a liquid with higher viscosity than water, such as heavy oil. Consult factory for power required to pump oils or liquids other than water.
- Bearings may be damaged causing excessive motor load.
- Pump speed may be too high. Check drive output to see if they are sized properly.
Pump clogs frequently:
- Liquid solution being pumped is too thick. Dilute if possible.
- Discharge velocity too slow. Open discharge valves to fully open; increase pump speed
Bearing running too hot:
- Drive misaligned; realign drive.
- Low or incorrect lubricant. Use proper type and level of lubricant.
- Suction and/or discharge pipe not supported properly. Check piping installation for proper support; take strain off the pump case and bearing frame.
