Pumping unit AN-125 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.
Power supply system - three-phase alternating current network with nominal voltage 380 V, frequency 50 Hz. Electricity quality standards according to GOST 31309-98.
Composition:
- sledge;
- piston pump NB-125
- electric motor;
- V-belt transmission;
- V-belt transmission guard.
The pump transmission shaft is driven by an explosion-proof electric motor via a V-belt transmission. The piston pump is bolted to the unit sledge. The electric motor is mounted on a plate, which is secured to the unit sledge with bolts. The sledge of the unit has slots for the mounting bolts of the motor plate for adjusting the tension of the V-belt transmission belts.
