Maintenance
WARNING:
Before attempting service on the pump or motor, DISCONNECT
the energy source to the pump. This will help prevent accidental start-up and
serious injury.
The Ampco ZP3 pump is designed to be easily disassembled for cleaning and maintenance
purposes. When performing maintenance on the pump it is important to inspect all wetted
parts for standard wear and damage. For inspection instructions please see page 13. For
rebuild information, see PD Pump Remanufacturing Program details on page 36. Prior to
disconnecting the pump, shut off all inlet and discharge valves, drain the pump (rinse if
necessary), and turn off all electrical supply to the pump (follow standard lock out procedures).
Pump Lubrication
Proper lubrication of gears and bearings is vital to the life of the pump. For pumps assembled
on bases with a gear reducer and motor, please refer to the proper manufacturer manual for
lubrication requirements. These manuals are sent with the pump from the factory. Important
lubrication points can be seen in Figure 16.
Figure 16: Lubrication Points
Both gears and bearings are shipped factory-lubricated with grease and oil. The oil used to
lubricate the gears should be changed every 500 hours with the quantities shown in Table 3.
The bearings should be re-greased every 250 hours. Excessive grease may build up inside
the gear case and should be cleaned out through the clean-out plugs shown in Figure 16, A.
