Performance
Receiving & Installation
Receiving Inspection
Upon receiving the pump, it should be inspected for damage or shortages.
If damage has occurred, file a claim immediately with the company that
delivered the pump. If the manual is removed from the packaging, do not lose
or misplace.
Storage
Any product that is stored for a period longer than six (6) months from the
date of purchase should be bench tested prior to installation. A bench test
consists of, checking the impeller to assure it is free turning and a runtest
to assure the motor (and switch if provided) operate properly. Do not pump out
of liquid.
Controls
Manual models require a separate approved pump control device or panel for
automatic operation. Be sure the electrical specification of the control
selected properly match the electrical specifications of the pump.
Submergence
The pump should always be operated in the submerged condition. The minimum
sump liquid level should never be less than above the pump’s volute (See
Figure 1).
Installation
These pumps are recommended for use in a sump, basin or lift station. The
sump, basin or lift station shall be sealed and vented in accordance with
local plumbing codes. This pump is designed to pump sewage, effluent or
wastewater, nonexplosive and noncorrosive liquids and shall NOT be installed
in locations classified as hazardous in accordance with the National
Electrical Code (NEC) ANSI/ NFPA 70 or Canadian Electric Code (CEC). The pump
should never be installed in a trench, ditch, or hole with
a dirt bottom. The legs will sink into the dirt and the suction will become
plugged.
The installation should be at a sufficient depth to ensure that all plumbing
is below the frost line. If this is not feasible, remove the check valve and
size the basin to accommodate the additional backflow volume.
Pumps are most commonly installed in simplex, duplex or triplex stations or
basins with a slide rail system, which allows the pump(s) to be installed or
removed without requiring personnel to enter the station, or resting on the
basin floor.
Discharge Piping
Discharge piping should be as short as possible and sized no smaller than the
pump discharge. Do not reduce the discharge pipe size below that which is
provided on the pump.
Both a check valve and a shut-off valve are recommended for each pump. The
check valve is used to prevent backflow into the sump. The shut-off valve is
used to manually stop system flow during pump servicing.
Liquid Level Controls
The level control(s) should be mounted on the discharge piping, a cable rack
or float pole. The level control should have adequate clearance so it cannot
hang up in it’s swing and that the pump is completely submerged when the level
control is in the “Off” mode. By adjusting the cord tether the control level
can be changed. One cycle of operation should be observed, so that any
potential problems can be corrected.
It is recommended that the level control float should be set to insure that
the liquid in the sump never drops below the top of the motor housing or a
minimum level of 10 inches above the basin floor.
Electrical Connections
Power/control cables:
The power/control cables mounted to the pump must not be modified in any way
except for shortening to a specific application. Any splice between the pump
and the control panel must be made in accordance with the electric codes. It
is recommended that a junction box, if used, be mounted outside the sump or be
of at a minimum Nema 4 construction if located within the wet well. DO NOT USE
THE POWER/ CONTROL CABLES TO LIFT PUMP. Always rely upon a Certified
Electrician for installation.
Installation & Service
Overload Protection:
Single Phase – The stator in-winding overload protector used is referred to as
an inherent overheating protector and operates on the combined effect of
temperature and current. This means that the overload protector will trip out
and shut the pump off if the windings become too hot, or the load current
passing through them becomes too high.
IMPORTANT ! – The overload will then automatically reset and start the pump up
after the motor cools to a safe temperature. In the event of an overload, the
source of this condition should be determined and corrected immediately.
WARNING! – DO NOT LET THE PUMP CYCLE OR RUN IF AN OVERLOAD CONDITION
OCCURS !
Three Phase – The Normally Closed (N/C) thermal sensor is embedded in the
motor windings and will detect excessive heat in the event an overload
condition occurs. The thermal sensor will trip when the windings become too
hot and will automatically reset when the pump motor cools to a safe
temperature. It is recommended that the thermal sensor be connected in series
to an alarm device to alert the operator of an overload condition, and/or the
motor starter coil to stop the pump. In the event of an overload, the source
of this condition should be determined and repaired. DO NOT LET THE PUMP CYCLE
OR RUN IF AN OVERLOAD CONDITION OCCURS!
Moisture Sensors – A normally open (N/O) sensor rated of 1 watt @330K ohms,
500 volt, is installed in the pump seal chamber which will detect any moisture
present. It is recommended that this detector be wired in series to an alarm
device or motor starter coil to alert the operator that a moisture detect has
occurred. In the event of a moisture detect, check the individual moisture
sensor probe leads for continuity, (∞ resistance = no moisture) and the
junction box/control box for moisture content. These situations may induce a
false signal in the moisture detecting circuit. If none of the above test
prove conclusive, the pump(s) should be pulled and the source of the failure
repaired. IF
A MOISTURE DETECT HAS OCCURRED MAINTENANCE SHOULD BE PERFORMED AS SOON AS
POSSIBLE!
If current through the temperature sensor exceeds the values listed, an
intermediate control circuit relay must be used to reduce the current or the
sensor will not work properly.

Wire Size: If longer power cable is required consult a qualified
electrician for proper wire size.
Pre-Operation
-
Check Voltage and Phase – Compare the voltage and phase information stamped on the pump name plate.
-
Check Pump Rotation – Improper motor rotation can result in poor pump performance and can damage the motor and/or pump. Check rotation on three phase units by momentarily applying power and observe the “kickback”.
“Kickback” should always be in a counter-clockwise direction as viewed from motor end or opposite to impeller rotation. Incorrect rotation for Single- Phase pumps is unlikely. If the rotation is incorrect contact factory. -
Name Plate – Record the information from the pump name plate to drawing in front of manual for future reference.
-
Insulation Test – An insulation (megger) test should be performed on the motor. Before the pump is put into service. The resistance values (ohms) as well as the voltage (volts) and current (amps) should be recorded.
-
Pump-Down Test – Be sure pump has been properly wired, lowered into the basin, sump or lift station, check the system by filling with liquid and allowing the pump to operate through its pumping cycle. The time needed to empty the system, or pump-down time along with the volume of water, should be recorded.
Service
Maintenance
No lubrication or maintenance is required.
Perform the following checks when pump is removed from operation or when pump
performance deteriorates:
a). Inspect motor and seal chambers for oil level and contamination.
b). Inspect impeller and body for excessive build-up or clogging.
c). Inspect motor, bearings and replace if required.
d.) Inspect seal for wear or leakage, replace if required.
Servicing
Reference Figures 6 .
Cooling Oil – Anytime the pump is removed from operation, the cooling oil in
the motor housing should be checked visually for oil level and contamination.
To check oil, set unit upright. Remove cap screws (6), lift conduit box
assembly (4) from motor housing (3), Do Not disconnect wiring from motor
leads. With a flashlight, visually inspect the oil in the motor housing (3) to
make sure it is clean and clear, light amber in color and free from suspended
particles. Milky white oil indicates the presence of water. Oil level should
be just above the motor when pump is in vertical position. Seal Chamber –
Drain oil from seal chamber by placing pump on its side with pipe plug (18)
downward and remove pipe plug (18). If the oil is found to contain
considerable water or other contamination, the shaft seal (19) should be
inspected and replaced if required.
Oil Testing
- Drain oil into a clean, dry container by placing pump on it’s side, remove cap screws (6), lift conduit box assembly (4) from motor housing (3). In sepatatecontainer drain seal chamber by removing pipe plug (18).
- Check oil for contamination using an oil tester with a range to 30 Kilovolts breakdown.
- If oil is found to be clean and uncontaminated (measuring above 15 KV. breakdown), refill the housing.
- If oil is found to be dirty or contaminated (or measures below 15 KV. breakdown), the pump must be carefully inspected for leaks at the shaft seal, conduit box, o-rings, pipe plug and pressure valve, before refilling with oil. To locate the leak, perform a pressure test. After leak is repaired, dispose of old oil properly, and refill with new oil.
Pressure builds up extremely fast, increase pressure by “TAPPING”
air nozzle. Too much pressure will damage seal. DO NOT exceed 10 P.S.I. in
motor housing and 20-25 P.S.I. in seal chamber
Pressure Test
Motor Housing – Oil should be at normal level. Remove pressure valve (10) from
motor housing (3). Apply pipe sealant to pressure gauge assembly and tighten
into hole (See Figure 2). Pressurize motor housing to 10 P.S.I. Use soap
solution around the sealed areas above the oil level and inspect joints for
“air bubbles”. If, after five minutes, the pressure is still holding constant,
and no “bubbles” /oil seepage is observed, slowly bleed the pressure and
remove the gauge assembly. Replace oil. Leek must be located and
repaired if pressure does not hold.
Seal Chamber – Check that seal chamber is full of oil by removing pipe plug
(18).
Apply pipe sealant to pressure gauge assembly and tighten into hole in bearing
bracket (16). Pressurize seal chamber to20-25 PSI and check for leaks.
Oil Replacement – Set unit upright and refill with new cooling oil as per
table.
Fill to just above motor as an air space must remain in the top of the housing
to compensate for oil expansion. Reassemble the o-ring (5) and conduit box (4)
to motor housing (3). Apply thread locking compound to cap screws (6) and
place into holes and torque to 15 ft/lbs.
DO NOT overfill oil. Overfilling of housing with oil can create
excessive and dangerous hydraulic pressure which can destroy the pump and
create a hazard. Overfilling oil voids warranty.
Oil Replacement: Seal Chamber – Refill chamber completely full with new
cooling oil or reuse the uncontaminated oil.

or crackes. Replace diaphragm by removing capscrews (41) and plate (40). Clean
vent holes in seal plate (20). Shaft Seal – Remove outboard rotating member of
seal (19), spring and inboard rotating member from shaft. Examine all seal
parts.
Inspect seal for signs of uneven wear pattern on stationary members, chips and
scratches on either seal face. DO NOT interchange seal components, replace the
entire shaft seal (19). If replacing seal, remove stationary by prying out
with flat screwdrive.
Motor and Bearings – Remove volute, impeller, seal plate and seal as
previously stated and drain oil from motor housing (3). Position unit upright,
using blocks to avoid resting unit on shaft. Remove cap screws (6) o-ring (5)
and conduit box assembly (4) from motor housing (3). Note connections and then
remove cable lead wires from motor lead wires and moisture & temperature
sensor wires from controlcable by removing connectors. Remove cap screws (12)
and vertically lift the motor housing (3) from bearing bracket (16). Replace

the black and white wires. If defective contact factoryor motor service
station. Pull motor rotor/ shaft with bearing (14) from bearing bracket (16).
Remove bearing (14) with a wheel puller if worn or damaged. If rotor or stator
windings are defective, replace the complete motor.
IMPORTANT! – All parts must be clean before reassembly. Reassembly
Bearings – Replace bearings, being careful not to damage the rotor or shaft.
If equipped, fill notch should face the rotor core for both upper and lower
bearings.
Apply adhesive compound to the shaft and press bearing (14) onto shaft,
position squarely onto the shaft applying force to the inner race of bearing
only, until bearing seats on shoulder of the shaft.In the same manner,
assemble upper bearing (2) to shaft.
Motor – Slide rotor with bearing (14) into bearing bracket (16) until bearing
seats on the bottom. Position motor housing and stator into pilot, install
wave washers inupper end bell.
IMPORTANT! Special wave washers in upper motor housing are required to
compensate for shaft expansion. These washers must be properly reinstalled to
give the required constant down force onthe motor shaft.
Position upper motor end bell aligning holes and thread cap screws into
bearing bracket (16) and torque to 16 ft./lbs.
Place all motor leads above the motor. Position square ring (15) on bearing
bracket (16) and lower housing (3) over motor and into pilot, aligning handle

Apply thread locking compound to threads on cap screws (12) and place into
holes and torque to 24 ft./lbs. Handle seal parts with extreme care. DO NOT
damage lapped surfaces.
Seal/Diaphragm – (See Figure 3) Clean and oil seal cavities in bearing bracket
(16) and seal Plate (20). Lightly oil (Do not use grease) outer surface of
inboard and outboard stationary members of seal (19). Press inboard stationary
member firmly into bearing bracket (16) and outboard stationary into seal
plate (20), using a seal pusher tool. Nothing but the seal pusher tool is to
come in contact with seal face.
**IMPORTANT!** Hammering on the seal pusher tool will damage the seal
face.
Be sure the stationary members are in straight and that the rubber ring is not
out of it’s groove. Lightly oil (Do not use grease) shaft and inner surface of
bellows on rotating member. With lapped surface facing bearing bracket (16),
slide rotating member onto shaft using seal pusher tool, until lapped faces
are together. It is extremely important to keep seal faces clean during
assembly. Dirt particales lodged between faces will cause the seal to leak.
Be sure driving lugs in retainer are matched in rotating member of seal (19).
Place spring over shaft and in place on rotating member, making sure it is
seated in retainer and not cocked or resting on bellows tail. Lightly oil
shaft and inner surface of outboard rotating member.
With tail section toward bearing bracket (16), slide rotating member onto
shaft with seal pusher tool until retainer engages spring and spring is
compressed slightly. Spring should be properly engaged in both retainers.
Reassemble the diaphragm (21) with “bulg” facing seal plate (20). Place plate
(40) on diaphragm (21) and insert capscrews (41) into plate and tighten.
Place seal plate (20) over shaft onto bearing bracket (16), being careful not
to damage outboard stationary member and align holes for cap screws (22).

Trouble Shooting Chart
**** Risk of electric shock. Always disconnect the pump from the power source before handling inspections or repairs.
| Symptom | Possible Cause(s) | Corrective Action |
|---|
Pump will not run
| 1. Poor electrical connection, blown fuse, tripped breaker or other interruption of power; improper power supply
2. Motor or switch inoperative (go to manual operation)
2a. Float movement restricted
2b. Switch will not activate pump or is defective 2c. Defective motor
3. Insufficient liquid level
| 1. Check all electrical connections for security. Have electrician measure current in motor leads, if current is within ± 20% of locked rotor Amps, impeller is probably locked. If current is 0, overload may be tripped. Remove power, allow pump to cool, then re-check current.
2a. Reposition pump or clean basin as required to provide adaquate clearance for float
2b. Disconnect level control. Set ohmmeter for a low rang, such as 100 ohms full scale and connect to level control leads. Actuate level control manually and check to see that ohmmeter shows zero ohms for closed switch and full scale for open switch. (Float Switch)
2c. Check winding insulation (Megger Test) and winding resistance. If check is outside of range, dry and re-check. If still defective, replace per service instructions.
3. Make sure liquid level is above the pump
4. Re-check all sizing calculations to determine proper pump size.
5. Check discharge line for restrictions, including ice if line passes through or into cold areas.
6. Remove and examine check valve for proper installation and freedom of operation
7. Open valve
8. Check impeller for freedom of operation, security and condition. Clean impeller cavity and inlet of any obstruction
9. Loosen union slightly to allow trapped air to escape. Verify that turn- off level of switch is set so that the suction is always flooded. Clean vent hole
10. Check rotation. If power supply is three phase, reverse any two of three power supply leads to ensure proper impeller rotation
11. Repair fixtures as required to eliminate leakage
12. Check pump temperature limits and fluid temperature
13. Replace portion of discharge pipe with flexible connector or tighten existing piping.
14. Turn to automatic position
15. Check for leaks around basin inlet and outlets
Pump will not turn off
| 2a. Float movement restricted
2b. Switch will not activate pump or is defective
4. Ecessive inflow or pump not properly sized for application
9. Pump may be air locked causing pump not to flow
14. H-O-A switch on panel is in “HAND” position
Pump hums but doesn’t run
| 1. Incorrect low voltage
8. Impeller jammed or loose on shaft, or inlet plugged
Pump delivers insufficient capacity
| 1. Incorrect low voltage
4. Ecessive inflow or pump not properly sized for application
5. Discharge restricted
6. Check valve partially closed or installed backwards
7. Shut-off valve closed
8. Impeller jammed or loose on shaft, or inlet plugged
9. Pump may be air locked causing pump not to flow
10. Piping fixtures leaking or discharge before the nozzle
Pump cycles too frequently or runs periodically when fixtures are not in use| 6. Check valve partially closed or installed backwards
11. Fixtures are leaking
15. Ground water entering basin
Pump shuts off and turns on independent of switch, (trips thermal overload protector). CAUTION! Pump may start unexpectedly.
Disconnect power supply.
| 1. Incorrect low voltage
4. Ecessive inflow or pump not properly sized for application
8. Impeller jammed or loose on shaft, or inlet plugged
12. Excessive water temperature (internal
protection only)
Pump operates noisily or vibrates excessively
| 2c. Worn bearings, motor shaft bent
5. Debris in impeller cavity or broken impeller
10. Pumprunning backwards
13. Piping attachments to building structure too loose or rigid
LIMITED WARRANTY
Manufacturer warrants, to the immediate purchaser and subsequent initial owner
during the warranty period, every new pump to be free from defects in material
and workmanship under normal use and service, when properly used and
maintained, for a period of eighteen (18) months from date of manufacture or
twelve (12) months from date of installation (which ever comes first). Failure
due to wear due to excessive abrasives is not covered. The initial owner is
the purchaser who first uses the pump after its initial installation, or for
non-permanent installation, the first owner who uses the pump. The date of
installation shall be determined by a dated sales receipt noting the model and
serial number of the pump. The dated sales receipt must accompany the returned
pump. Product will be repaired, replaced or remanufactured at Manufacturer’s
option. No allowance will be made for shipping charges, damages, labor or
other charges that may occur due to product failure, repair or replacement.
This warranty does not apply to and there shall be no warranty for any
material or product that has been disassembled without prior approval of
Manufacturer, subjected to misuse, misapplication, neglect, alteration,
accident or act of God; that has not been installed, operated or maintained in
accordance with Manufacturer’s installation instructions; that has been
exposed to outside substances including but not limited to the following:
sand, gravel, cement, mud, tar, hydrocarbons, hydrocarbon derivatives (oil,
gasoline, solvents, etc.), or other abrasive or corrosive substances, wash
towels or feminine sanitary products, etc. in all pumping applications. The
warranty set out in the paragraph above is in lieu of all other warranties
expressed or implied; and we do not authorize any representative or other
person to assume for us any other liability in connection with our products.
