Lubricant pump PA 12*

electricworm gearstationary

The pump is designed for lubricating friction nodes in vehicle chassis 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. Pump marked PA 12G is a type of PA12 pump designed for use in underground mines not endangered by explosion. The pump consists of the following subassemblies: a tank with a grease feeding device, a drive train consisting of an electric motor, a single-stage worm gear placed in a common housing with an eccentric drive train, two pumping units of different performance values consisting of pumping elements in which the pistons are driven by a cam drive system, check valves and pressure hoses, a control valve consisting of a control slide, two overflow valves, the left of which is equipped with a valve piston movement indicator, an inductive non-contact switch that interacts with the piston movement indicator and a pressure gauge, a control device that operates in conjunction with an inductive proximity sensor located on the control valve, an electrical signalling device with minimum and maximum grease level in the tank (optional equipment).
