Maintenance
As the motor is oil-filled, no lubrication or other maintenance is
required. Severe operating environments will require more
frequent checks. For any issues that are not resolvable, contact
Liberty Pumps for further assistance.
Some pumps have an air bleed hole to help prevent airlock. A
small spray of water from this hole is normal while pump is
running.
In the event the pump becomes clogged, the inlet screen can be
removed to gain access to the pump impeller. Once the
obstruction is removed, the anti-air lock hole should be cleaned.
To keep the pump/pump system operating smoothly, perform the
following routine checks:
Monthly
1. Pumps that are idle for more than a month in a dry basin
should have impellers manually operated through the breaker
panel monthly to lubricate the seals.
2. Pumps that are idle in a wet basin must be removed.
Quarterly
1. Check pumps for corrosion and wear.
2. Check for free and unobstructed float switch operation and
float switch condition.
3. Inspect for proper check valve operation.
4. For multiple pumps, check for balanced operating times.
Uneven times indicate a defective unit, float switch or control.
5. Inspect the control panel for any presence of moisture in
enclosure, loose connections, and general component
condition.
Annually
1. Inspect and clean basin. Replace any defective components.
Field Service on Hazardous Location Pumps
The power and control cord are not field replaceable. If either cord
is compromised, the entire pump must be brought to an
authorized hazardous motor enclosure repair facility approved by
Liberty Pumps.
The only allowable repair/replacement without compromising the
hazardous location rating of the pump is the lower shaft seal. A
certified repair shop should perform this task since they have the
capability to clean and flush the mid oil chamber.
Otherwise, the pump must be returned to Liberty Pumps or an
authorized hazardous repair facility for electrical and motor
service. This will ensure the integrity of the hazardous location
rating of the pump and comply with Liberty Pumps warranty
requirements.
Troubleshooting
No repair work shall be carried out during the warranty period
without prior factory approval. To do so may void the warranty.
Liberty Pumps, Inc. assumes no responsibility for damage or injury
due to disassembly in the field. Disassembly, other than an
authorized hazardous motor enclosure repair facility approved by
Liberty Pumps or its authorized service centers, automatically
voids warranty.
