INSTALLATION & SERVICE

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 - Before the pump is put into service, an insulation (megger) test should be performed on the
motor, 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 and bearings.
d). Inspect seal for wear or leakage.
Servicing
NOTE: Item numbers in ( ) refer to Figures 4&5.
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 (40) from housing (31). With a
flashlight, visually inspect the oil in the housing (31) 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.
Oil Testing
Drain oil into a clean, dry container by placing pump on it's side, remove pipe plug (40), from housing (31).
•
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, cable assembly and pipe plug, 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 Test (If oil has been drained), Remove pipe plug (40) from housing (31). Apply pipe sealant to pressure
gauge assembly and tighten into hole. Pressurize motor housing to 10 P.S.I. Use soap solution around the sealed
areas and inspect joints for "air bubbles".
If, after five minutes, the pressure is still holding constant, and no "bubbles" are observed, slowly bleed the pressure
and remove the gauge assembly. Replace oil. Leek must be located and repaired if pressure does not hold.
Pressure Test (If oil has NOT been drained) - Oil should be at normal level. Remove pipe plug (40) from housing (31). Apply pipe
sealant to pressure gauge assembly and tighten into hole. 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". For sealed areas below oil level, leaks will seep oil. 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.
