Our full line of well service pumps are designed and manufactured by Caterpillar, in Caterpillar factories for single-source package confidence. High quality materials, advanced manufacturing techniques, heat treatment processes, high-performance surface treatments and special coatings ensure exceptional product life and performance. In the field, equipment either proves itself or it doesn’t.


Our fluid ends are built for maximum durability in a range of sizes for application flexibility. They are compatible with industry-standard 8” and 10” stroke power ends, and designed to be interchangeable across our whole line and with other industry standard fluid ends. Our stainless steel fluid ends offer improved corrosion resistance, especially when in contact with recycled water. They are fully interchangeable with the existing Cat carbon steel product line, and offer a reduced total cost of ownership in high-stress applications.

Valves & Seats

We offer one-piece valves with injected inserts, geometrically designed for reduced impact forces and longer life. They deliver an increased flow area and reduce the risk of washouts by directing fluid toward the discharge valve. They will fit nearly any well stimulation pump, and the seats can be used with multiple valve changes for reduced maintenance time and longer maintenance intervals.

Power eNDS

Cat power ends match the industry standard footprint, so they’re ready to integrate into existing well service trailer designs. They are designed for high reliability, with a fully welded structure and additional internal supports. The nose-plate-to-frame design increases structural strength, and all bull gears are forged or fabricated. The one-piece forged crankshaft further increases their durability.
