AN-50 with diesel engine on the frame

Pumping unit AN-50 is designed for injection of flushing fluid during drilling of oil and gas wells; for injection of water into the reservoir during intensification of oil production; for pumping of various non-aggressive liquids, including watered oil.

Clay solution or water can be used as a flushing or pumping liquid. The content of mechanical impurities (sand, solid particles of drilled rock) should be no more than 1% by volume with hardness up to 1200 HV units.
Type of climatic execution - U1, placement category 2 according to GOST 15150-69.

Composition:

  • frame;
  • piston pump;
  • D-144 engine or ZMZ-511 engine (GAZ-53);
  • angle reducer;
  • transmission;
  • control system for gears, clutch, fuel pump and engine stopping, pump activation.

The pump transmission shaft rotation is driven from the D-144 or ZMZ-511 (GAZ-53) engine through an angle reducer. The piston pump is mounted to the machine frame with bolts. The engine is mounted on the plate, which is secured to the machine frame with bolts.
