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.)

Technical Data

Maximum Air Pressure

140 psi (10 bar)

Minimum Air Pressure

20 psi (1.5 bar)

Maximum Delivery

0.7 lb/min (21 cu.in./min)

Air Inlet Thread

1/4” NPT (F)

Grease Outlet Thread

1/4” NPT (F) (includes 1/2”-27 male conn)

Air Piston Diameter

2.75” (70mm)

Air Piston Stroke

1.5” (35mm)

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.
