Frac Pump Trailer

Conventional units driven by a high-horsepower diesel engine coupled through a transmission to the plunger pump, providing self-contained mobile pumping without external power. They remain the most common spread unit because each trailer is independent of site infrastructure.

Trailers in which the plunger pump is driven by a variable-frequency-drive electric motor fed from a site power grid, gas turbine, or generator set. They reduce on-trailer engine maintenance and emissions and allow finer rate control.

Units whose prime mover burns a blend of diesel and field/natural gas, or a gas turbine driving the pump, to lower fuel cost and emissions versus pure diesel. The pump and fluid end are otherwise comparable to diesel units.

Trailers built around a three-plunger positive-displacement fluid end, offering robust high-pressure capability at moderate flow rates. Triplex configurations are common where higher discharge pressure is prioritized over peak rate.

Trailers built around a five-plunger fluid end, delivering higher flow rate and smoother discharge with reduced pulsation compared with triplex units. They are favored on modern high-rate fracturing spreads.

Complete units assembled to a customer specification, integrating the chosen pump, power end, driver, transmission, cooling, lube, and control systems onto a road-legal trailer chassis. Build scope covers frame fabrication, piping, and commissioning.

Used units rebuilt to restore rated horsepower and pressure, typically including fluid-end replacement, power-end overhaul, repowering, and re-piping. Refurbishment extends service life at lower cost than a new build.

The wear-intensive high-pressure section of the pump (housing, plungers, packing, valves, and seats) and related expendables supplied for trailer maintenance. These are consumable items replaced frequently due to abrasive proppant service.
