High & Ultra high pressure plunger pumps

High & Ultra High Pressure Plunger Pumps

Precision Engineering for Demanding Applications

Our range of high and ultra-high pressure plunger pumps is engineered to perform in the most demanding industrial, offshore, and surface preparation environments.

Operating at pressures from 70 to 2,800 bar (1,000 to 40,000 psi) and flow rates up to 800 l/min (214 gpm), with power ratings from 30 to 375 kW (40 to 500 hp), these pumps deliver outstanding reliability, performance, and service life.

Every pump undergoes a three-hour endurance and performance test, during which critical functions are monitored, recorded, and verified to meet exacting standards.

Our pumps are manufactured in-house in West Sussex, United Kingdom, where they produce key components — including crankshafts and gearboxes — using state-of-the-art CNC machinery, machine-tending robots, and advanced inspection systems to guarantee precision and consistency.
