High Pressure Pumps

High pressure water jet pumps for water jet cutters

For nearly half a century we have been designing and manufacturing ultrahigh pressure pumps for incredible pressures of up to 14,000 bar for industrial use. Whenever reliability at high pressures is of utmost importance Uhde High Pressure Technologies in Hagen, Germany is a name which is recognized worldwide.

Our high pressure pumps - the core element of a waterjet cutting system - with steeples working pressures of up to 6,000 bar are implemented in all relevant industrial sectors: from food industry over glass and stone to aerospace.

Starting at the first development stage and continuing with manufacturing of parts, software programming, and assembly until the final test run: water jet cutting with Uhde High Pressure Technologies means: everything takes place at our factory in Hagen, Germany.

Why choosing Uhde High Pressure Pumps?
