Mud pumps

Modern triplex mud pumps (UNBT) of 800 to 2200 hp power range.

Design features:
•pump power and pressure on each piston diameter allow forced drilling practices;

  • forged fluid ends made of high-strength alloyed steel;
  • ion nitriding of the gear transmission;
  • hydraulic seal of the cylinder and piston assembly;
  • double-chamber seal of the slide block rod for excluding oil leakage from the case, its contamination with drilling mud;
  • lubrication of reduction gear through two systems:

-pressure lubrication with automated maintaining of constant pressure in the oil line;

-gravity oil system lubrication from storage trays;

  • safety valve of the locking device;
  • drive transmission at any side of the pump or at the both sides;
  • suction and discharge headers for pipes connection from both sides.

Advantages of UNBT-series pumps:

  • possibility of forced drilling practices
  • full accordance to drilling practices requirements;
  • minimum degree of irregularity of discharge pressure;
  • less consumption of valves and piston rods in comparison with double-acting duplex pumps;
  • guarantee of the pump specified life;
  • mud pumps drive switching-off when pressure in the delivery pipe is exceeded, with simultaneous release of the excess pressure;
  • pump stroke-independent lubrication.
