5. Maintenance Overview
The timing for maintenance of the pump is established primarily on past performance. Each installation is
different. Therefore, regular inspections, and detailed maintenance records of past performance can be invaluable
for determining future preventative maintenance intervals. For motor maintenance instructions consult the motor
manufacturer.
B EFORE PERFORMING ANY MAINTENANCE REQUIRING PUMP DISASSEMBLY , BE SURE TO FLUSH AND
DRAIN PUMP THOROUGHLY WITH A NEUTRALIZING FLUID . W EAR PROTECTIVE CLOTHING AND HANDLE
EQUIPMENT WITH PROPER CARE .
When changing a pump from one service to another, be sure to check that all wetted parts of the pump are
compatible with the fluid to be handled and that the motor is sufficiently sized for the application. If in doubt
contact your Pulsafeeder representative for assistance.
All magnetic drive couplings have a specific maximum torque limit. If this torque is exceeded
the drive will decouple. Operation in the decoupled mode should be avoided as high
temperatures could be generated.
Whenever gear pumps exhibit reduced flow rates, inability to maintain pressures, noisy or otherwise abnormal
operation, first refer to the troubleshooting section at the end of this manual. If the problem cannot be resolved the
pump must be inspected for wear or damage. Eclipse Standard/Eclipse Hypo Series gear pumps can be easily
opened for cleaning and inspection without disturbing piping connections by removing the pump front housing
cover.
Where inspection shows wear, rebuilding the pump using a KOPKit is strongly recommended. Quite often,
original hydraulic performance can be restored by simply changing the KOPKit alone.
Magnets (both drive and driven) can attract small particles of debris during handling. Always visually
inspect the magnetic parts of the pump for cleanliness during re-assembly. Wipe carefully to remove
debris, particles, or other small parts without damaging the surface of the magnets.
