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. The
Resistance values should be greater than 1 M
ohm. If abnormal readings are obtained contact
your 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
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 severely
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 the seal face.
SPARE PARTS
In order to obtain spare parts identify the
required parts by looking at the appropriate
cross sectional drawing and listing, and contact
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, Blue #242 thread locking compound,
petroleum jelly and anti- seize compound are on
hand.
