As specialist manufacturers of high pressure pump systems, we design and engineer market-leading solutions which set the standards for use in the most harsh operating environments around the globe. We are an independent company with one focus: to build the best high pressure systems on the market. | Ultra Low Friction Labyrinth Seal System | Robust Pump Gearend Totally unique, our HP plunger pump labyrinth seal system is formed by circumferential labyrinth grooves between the plunger and the seal bushing, creating a low friction liquid seal. Our seal technology has helped us achieve the single most important advance in pump reliability, giving significant service life and uptime advantages over traditional packing seal technology. To prove it, why not ask us to demonstrate the ‘drop test’ to you? The in-built speed reducer installed in the high pressure pump Our HP pump gearend incorporates critical standard features which are not included by many competitors. gearend allows direct drive from the diesel engine, eliminating the need for large ratio V-belt drives and additional guarding: this also The gearend pressure lubrication system includes an oil filter and oil cooler. eliminates bearing side load damage, and reduces weight and maintenance requirements whilst enabling an extremely compact unit A built-in lubrication pump ensures that oil is delivered to all bearing design. surfaces and that the oil is circulated through the on-board 25-micron oil filters to ensure maximum oil cleanliness: this, combined with our • Safety Shutdowns • Pump - low inlet water pressure • Pump - high oil gearend oil cooler, which maintains pump lube oil at temperatures temperature • Pump - high inlet water temperature • Pump below 70°C, protects your high pressure pump power end even • Direct Drive - high discharge pressure • Engine - low oil pressure • Engine when operating on continuous duty, resulting in long term reliability. Direct drive through | Reduced Pump Maintenance Repair when you want to, not when you have to….. With our labyrinth seal system design, emergency repairs to the high pressure pump whilst ‘on the job’ are eliminated. As labyrinth wear is gradual, over many thousands of hours, you will experience that scheduled repairs and maintenance are all that is necessary. • Water Tank | Direct Drive - Efficient And Maintenance Free • Boost Pump • Performance Options Multi performance options up to 3,000 bar (43,500 psi) via a simple conversion kit installation.
