WellService Pumps

Three-plunger reciprocating pumps that are the most common configuration for cementing, acidizing, and general pressure pumping. The odd cylinder count produces relatively smooth flow with lower pressure pulsation than duplex designs.

Five-plunger reciprocating pumps that deliver smoother flow and higher rod-load capacity than triplex units for the same displacement. Used in higher-rate fracturing and stimulation packages where reduced pulsation extends fluid-end life.

Pumps and pump units configured for placing cement slurry, including units in the HT400 class used for primary and remedial cementing. They are rated for abrasive, high-density slurry service across a wide range of rates and pressures.

Pumps built with corrosion-resistant wetted parts for pumping acids and other stimulation fluids during matrix and well treatment jobs. Material selection and seal compatibility target the chemical service rather than peak horsepower.

Integrated packages combining the pump, prime mover, transmission, and controls on a skid or chassis for field deployment. Sold as complete well service or stimulation pump packages ready to tie into surface treating lines.

The two major pump assemblies offered as units or major repair components: the fluid end houses the plungers, valves, seats, and packing, while the power end carries the crankshaft, connecting rods, crossheads, and main bearings.

Replaceable wetted components including plungers, valves, valve seats, packing, and seals that wear during service. These are stocked as routine maintenance items and matched to the specific pump model.

The diesel engines (well service engines) and transmissions that drive the pump through the power end. Rated by brake horsepower and matched to the pump's input speed and rod-load limits.
