Page 1 Z-Series: Metric Components Service Manual This service manual includes installation, operation, and maintenance instructions for Ampco Pump Company’s Z-Series: ZCM and ZCHM. Failure to learn the correct procedures for installing and servicing the pump from this manual could result in equipment failure.
Page 2: Pump Installation
PUMP INSTALLATION Receiving pumps: Visually inspect shipping crate(s)/pallet(s) for damage. Ampco pumps will be shipped in boxes labeled Ampco Pumps or in crates. If there is any damage it is imperative to notify the driver at the time of delivery. Failure to do so will make it difficult, if not impossible, to file a damage claim and Ampco Pumps will not be held accountable.
Page 3 General Piping Notes  Pipe hangars or other supports must be used at proper intervals to ensure proper piping support near the pump. Do not use the pump to support piping!  When flange bolts are tightened no strain should be transmitted to the pump, thus suction and discharge piping should be supported independent of the pump and care should be taken that the pump and piping are properly aligned.
Page 4  High point such as loops or arcs must be avoided as they may create air pockets, throttle the system, and produce erratic pumping.  A valve must be installed in the suction piping in order to isolate the pump during shutdown and maintenance, and to facilitate pump removal.
Page 5 Priming The Z-Series pump is not a self-priming pump and must be completely filled with the pumping liquid before operation. If the system has a positive suction head priming can be done by opening the valve in the suction piping as well as the pump’s air vents to allow the liquid to enter the pump casing.

There may be valve chatter during transient period during valve adjustment. Be aware that the pump’s motor is specified for the flow and pressure specified by the customer and that higher flow rates could damage the motor.
