Recommendations and Warnings

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 run test to assure the motor (and switch if provided) operate properly.

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, non-explosive and non-corrosive 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 or duplex stations or basins with a slide rail system (Barmesa SRC), 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 low during pump servicing.

Liquid Level Controls
The level control(s) should be mounted on the discharge piping, a cable rack or a float pole. The level control should have adequate clearance so it cannot hang up in its 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 l f oat 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 ower cable:
The power cable mounted to the pump must not be modified in any way except for shortening to a speci ic 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 CABLE TO LIFT PUMP.

Always rely upon a Certified
Electrician for installation.

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.

Installation & Service

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.

DO NOT ALLOW THE PUMP TO 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 ALLOW THE PUMP TO 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, (0° 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.

TEMPERATURE SENSOR ELECTRICAL RATINGS

Volts| Continuous Amperes| Inrush Amperes
110-120| 3.00| 30.0
220-240| 1.50| 15.0
440-480| 0.75| 7.5
600| 0.60| 6.0

Wire Size: If longer power cable is required consult a qualified electrician for proper wire size.

Pre-Operation

1. Check Voltage and Phase – Compare the voltage and phase information stamped on the pump name plate.

2. 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. Impeller rotation is counter- clockwise as viewed from bottom of pump.

3. Name Plate – Record the information from the pump name plate to drawing in front of manual for future reference.

4. 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.

5. 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.

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 chamber for oil level and contamination.
b) Inspect impeller and body for excessive build-up or clogging.
c) Inspect motor, bearings and shaft seal for wear or leakage.

Servicing
NOTE: Item numbers in ( ) refer to Figure 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 placing pump on it’s side, remove cap screws (6), lift conduit box assembly (4) from motor housing (3). In separate container drain seal chamber by removing pipe plug (18).
• Check oil for contamination using an oil tester with a range to 30 kV 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 PSI  in housing and 20-25 PSI 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 PSI.

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 housing (16). Pressurize seal chamber to 20-25 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/Ibs.

DO NOT overfill oil.
Overfilling of housing with oil can create excessive and thee 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.

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 screwdriver.

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 and temperature sensor wires from control cable by removing connectors. Remove cap screws (12) and vertically lift the motor housing (3) from bearing housing (16). Replace square ring (15) if damaged or cut. Remove the upper motor bolts and lift upper end bell from motor (1). Remove wave washer. Remove upper bearing (2) with a wheel puller if damaged or worn.

Vertically lift stator (1) from rotor/shaft. Inspect windings for shorts and resistance. Test the temperature sensors by checking for continuity between the black and white wires. If defective contact factory or motor service station. Pull motor rotor/shaft with bearing (14) from bearing housing (16). Remove bearing (14) with a wheel puller ifworn 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 housing (16) until bearing seats on the bottom. Position motor housing and stator into pilot, install wave washers in upper 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 on the motor shaft.

Position upper motor end _ bell aligning holes and thread cap screws into bearing housing (16) and torque to 16 ft/Ibs. Place all motor leads above the motor. Position square ring (15) on bearing housing (16) and lower housing (3) over motor and into pilot, aligning handle so that it is parallel to motor end bell reliefs.

Seal/Diaphragm – (See Figure 3) Clean and oil seal cavities in bearing housing (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 fi rmly into bearing housing (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 housing (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 to cocked or resting on bellows tail. Lightly oil shaft and inner surface of outboard rotating member. With tail section toward bearing housing (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 (22) on diaphragm (21) and insert capscrews (23) into plate and tighten.
Place seal plate (20) over shaft onto bearing housing (16), being careful not to damage outboard stationary member, and align holes for cap screws (25).
