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. Incorrect rotation for
single phase pumps is unlikely. If the rotation is incorrect contact factory.
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 sump
basin, 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
Servicing
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.
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 pipe plug from housing.
With a flashlight, visually inspect the oil in the housing the 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.
Oil Testing
1) Drain oil into a clean, dry container by placing pump on its side, remove pipe plug from
housing.
2) Check oil for contamination using an oil tester with a range to 30 Kilovolts breakdown.
3) If oil is found to be clean and uncontaminated (measuring above 15 kV breakdown)
Refill the housing.
4) 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, cable assembly, square
ring and pipe plug before refilling with oil. To locate the leak, perform a pressure test.
