Installation, Operation & Maintenance Manual
PREVENTIVE MAINTENANCE
Regular preventive maintenance will help ensure
longer pump life and more reliable operation. It is
recommended that pumps in intermittent operation
be inspected twice a year and pumps in continuous
operation be inspected every 1,000 hours. The
following is a listing of required inspection and
maintenance items.
If any of the problems described in the
following list exists stop operating the pump to
avoid damage or personal injury.
1. CABLE ENTRY
Make sure that the cable entry flange and strain
relief clamp are tight. If the cable entry is showing
signs of leakage remove cable from entry, remove
grommet, cut a piece of cable off so that the
grommet seats on a new portion of the cable,
replace grommet, and reinstall cable assembly,
into the top of the motor.
Note: Explosion Proof cables are sealed with a
Factory Mutual Approved potting compound.
Please consult factory for instruction.
2. CABLES
Inspect the cable for cuts, scrapes or sharp bends.
If the outer jacket is damaged, replace the cable.
Do not attempt splices within wet wells.
3. MOTOR INSULATION RESISTANCE
Megger the insulation between the phases and
between any phase and ground. Resistance
values should be greater than 1 M ohm. If
abnormal readings are obtained, contact
authorized service center immediately.
4. EXTERNAL PARTS ON PUMP
Make sure that all screws, bolts and nuts are tight.
Check the condition of pump lifting eyes and
replace if damaged or worn. Replace any external
part that appears worn or damaged.
5. SEAL CHAMBER OIL
Caution seal chamber may be pressurized
Note: Use extreme care when removing the seal
chamber plug, as the chamber may become
pressurized if seal failure has occurred. Check the
condition of the oil to see if any water leakage has
occurred. Lay the pump on its side with the plug
facing upward and remove the oil fill plug. Drain
the oil from the seal chamber into a transparent
container. Check for impurities and emulsification
(oil is cream-like). If water intrusion has occurred
check lower mechanical seal and replace if
necessary. Refill seal chamber with fresh oil.
Refer to shop manual for type and quantity of oil.
6. IMPELLER
Periodically inspect impeller by turning pump on its
side, remove suction strainer nuts and strainer to
expose impeller and relocate position of adjusting
plate (suction cover) as needed. Replace the
impeller if it is damaged or worn.
7. PROFILE SEAL
When pump is removed for any service, carefully
inspect the profile seal for signs of damage or
improper sealing. Be sure the contact patch is fully
around seal face.
SPARE PARTS
In order to obtain spare parts contact an authorized
HOMA PUMP TECHNOLOGY representative with
the parts required and the pump serial number.
Authentic Homa Pump Technology parts shall be
used to maintain warranty.
Note: Explosion Proof pumps must be identified as
such, and the pump serial number must be
referenced for proper parts identification.
RECOMMENDED TOOLS AND
SUPPLIES
In addition to ordinary, standard tools and lifting
devices, ensure that complete set of metric Allen
wrenches, dead blow hammer, impeller puller,
Loctite 242 (Blue) thread locking compound,
petroleum jelly and Anti-seize compound are on
hand.
