Bosch Rexroth PGF Series Internal Gear Pump
Bosch Rexroth PGF external gear pumps consist of a gear wheel pair and housing with a front and one rear cover. The drive shaft drives one of the two gear wheels which again drives the second gear wheel in the opposite direction. Due to the rotation, hydraulic fluid is entrapped in the gear chambers and delivered along the housing from the suction port to the pressure port. The flow per rotation roughly corresponds to the total of both gear chamber volumes.
The 2X component series gear pump sizes are: frame size 1: 1.7, 2.2, 2.8, 3.2, 4.1, 5, 6.3, 8, 11, 13, 16, 19, and 22, and frame size 2 comprising: 6.3, 8, 11, 13, 16, 19 and 22, with the 3X component series sizes being: 20, 25, 32, and 40. Peak pressure is up to 250 bar and a maximum displacement volume of 40.5 cm3.
Other features of the Bosch Rexroth PGF gear pump include:
- Fixed displacement;
- Low operating noise;
- Low flow pulsation;
- Suitable for broad viscosity and speed ranges;
- Very good suction characteristic;
- Long life cycle due to plain bearings and sealing gap compensation.
