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.
