PGH High Pressure Gear Pumps

The Bosch Rexroth PGH High Pressure Gear Pump is a fixed displacement pump designed for high pressure hydraulic applications, featuring a maximum operating pressure of 350 bar. It operates with notably low operating noise and low flow pulsation, making it suitable for a broad range of viscosities and speeds. The pump achieves high efficiency, even at low speed, due to an internal design that incorporates sealing gap compensation. This design ensures a long service life and consistent performance by minimizing internal leakage. The primary function of the PGH pump is its use in fatigue-endurable drives with high pressure and load cycles, commonly found in plastics processing machines, presses, and test stands.
