The pneumatic grease pump is an assembly consisting of a cam pneumatic motor connected to a piston-pump located at the bottom of the suction unit. This equipment is required in all working conditions where grease needs to be pumped under pressure (such as bearings, hubs, pins, fittings, etc.).

This machine can be considered as a pressure pnumo-hydraulic multiplier: pressureratio (PR) is given by the ratio between the pneumatic (motor) and the hydraulic (pump) sections. When the motor is supplied with a pressure (P1), the pump will generate another pressure (P2) as result of the multiplication P1XPR.

The motor consists of a pneumatic cylinder slave to an automatic device which alternatively supplies two chambers determining the in-continuous movement.
Pump designing features allow the suction of high viscosity fluids without pumppriming or oil addition for pump operation.

The pump, combined with a suitable grease follower plate completed with O-ring-seals both on the hub and on the outer lip, allows the suction of the whole lubricant inside the drum with no generation of air pockets.
