Bosch Rexroth PGH-3X Series Internal Gear Pump
Gear Pumps – Internal
Bosch Rexroth PGH internal gear pumps are gap-compensated with fixed displacement. The hydrodynamically mounted pinion shaft drives the toothed internal gear. The tooth clearances opening in the suction area suck in the hydraulic fluid and transport it away from the pinion shaft and internal gear. Suction and pressure area are separated by the radial compensation elements and the tooth engagement between internal gear and pinion shaft.
The PGH-3X series gear pump is available in frame size 4: 20, 25, 32, 40, and 50 and frame size 5: 63, 80, 100, 125, 160, 200, and 250. The pump has a peak pressure of 350 bar and a maximum displacement of 250 cm3.
Other features of the gear pump include:
- Fixed displacement;
- Low operating noise;
- Low flow pulsation;
- High efficiency at low speed and viscosity due to sealing gap compensation;
- Suitable for broad viscosity and speed ranges;
- Suitable for operation with HFC fluid.
