In practice triplex pumps have the following advantages:

      

  •       The triplex pump provides a more even delivery so that discharge variations are about half those of a duplex pump. This provides a longer life of pump parts, hoses, etc.

  •       The total weight of a triplex pump is approximately 70 % of that of a duplex pump with the same capacity and it also requires less space.

  •       Triplex pumps are more accessible than duplex pumps and consequently, maintenance is faster and cheaper.


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.
