The PM Pump is a compressed air-operated reciprocating piston pump. This high capacity demand pump is compatible with mineral and synthetic grease and suitable for large installations with long length piping supplying several fluid outlets simultaneously. This pump is mounted directly on 120 lb and 400 lb drums or bulk tote.
This pump is self-priming. To prime it the first time, it is convenient to connect the air supply to the pump while keeping the outlet gun opened and slowly increase the air pressure by using a pressure regulator. Once grease starts flowing through all the outlets, the pump is primed. The pump starts to pump when an outlet valve is opened, for example a grease control gun.
