The pump is designed for lubricating friction nodes in vehicle chasses and machines. Lubricant is fed to the reception point equipped with a ball nipple by a lubrication gun joined to the pump by a flexible hose. The pump is recommended for equipping lubrication stands in vehicle and machine service stations. It may also be used to lubricate friction nodes in dredging excavators, dredgers and other equipment of strip mines, as well as in underground mine workings (e.g. in copper mines).

The pump consist of the following assemblies:
- a tank with a grease feeding device
- a power transmission system comprising an elecrical motor, singlestage worm gear put into a common body with an eccentric power transmission system,
- two forcing units of various capacity, comprising forcing elements in which pistons receive power from the eccentric power transmission system, return valves and pressure conduits,
- contron valve comprising a control slide, to overflow valves (the lest one equipped with a valve piston movement gauge, - control device mating an inductive proximity sensor placed in the
control valve,
- an electric device signalling the minimum and maximum level of lubricant in the tank (special accessory)
