PM3 Pump
55:1, Air-operated, Grease
General
The PM3 Pump is a compressed air-operated reciprocating piston pump designed for high pressure
greasing. These pumps are compatible with all types of mineral and synthetic greases (up to NLGI
grade 2 viscosity). These pumps can be supplied as separate components or as complete systems
with all the elements necessary for installation. These pumps can be mounted on mobile units as well
as on fixed drums and connected to a distribution line for single reel use.
Operation
This pump is self-priming. To prime it the first time, connect the air supply to the pump and slowly
increase the air pressure from 0 to the desired pressure using a pressure regulator, while keeping
the outlet valve opened. Once grease begins to flow through the grease gun/guns, the pump is
primed.
(Note: It is important that the foot valve of the pump does not come into contact with
contaminated surfaces, such as a workshop floor, as it may become contaminated with dirt or
foreign particles that can damage the seals.)

Installation
These pumps must be mounted on drums using
covers fitted with a 2” bung. Loosen the star nut
(48a) of the bung adapter to remove the lower
nut (48c) and screw this into the 2” bung
opening of the cover. Place the star nut (48a)
and the three jaws (48b) on the suction tube.
Lower the pump through the opening and fasten
the assembly at the desired height. Secure the
cover to the drum with the thumbscrews.
Always keep fingers and hands away from
moving parts. Do not dent or damage the
riser tube.
Ensure that the mounting surface and
attachments are strong enough to
support the lift and pump assembly
during operation.
