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).
