Introduction to common samples of Rexroth gear pumps

Thread Content

Hydraulic products under Bosch Rexroth can generally be divided into three categories: Rexroth piston pumps, Rexroth vane pumps, and Rexroth gear pumps. In terms of appearance, the Rexroth gear pump differs significantly from the first two types. We can analyze the differences by examining a sample of the Rexroth gear pump. Below are samples of three different types of Rexroth gear pumps:
Rexroth PGH 3X fixed-displacement gear pump
Model series: PGH 3X
Model specifications available: 4, 5
Component series: 3X
Maximum operating pressure: 350 bar
Displacement: 020–250 cm³;
– Fixed displacement
– Low operating noise
– Low flow pulsation
– High efficiency even at low speeds and with low-viscosity fluids, thanks to seal clearance compensation
– Suitable for a wide range of viscosities and speeds
– All frame sizes and specifications can be combined in any way
– Can be used in combination with internal gear pumps, vane pumps, and axial piston pumps

Rexroth PGH 2X series gear pump
Model series: PGH 2X
Model specifications available: 2, 3, 4, 5
Component series: 2X
Maximum operating pressure: 350 bar
Displacement: 005–250 cm³;
– Fixed displacement
– Low operating noise
– Low flow pulsation
– High efficiency even at low speeds and with low-viscosity fluids, thanks to seal clearance compensation
– Suitable for a wide range of viscosities and speeds
– All model specifications and displacement values can be combined with each other

Rexroth PGF 1X series gear pump
■ Fixed displacement
■ Frame sizes: 1, 2, and 3
■ Component series: 2X and 3X
■ Maximum operating pressure: 250 bar
■ Maximum displacement volume: 1.7 to 40 cm³;
These are the three common series of Rexroth gear pumps as compiled by Autos. The appearance of other types is roughly similar to these three. If it is still not possible to distinguish between Rexroth gear pumps, Autos recommends asking the Rexroth distributors more questions when making a purchase; they will be happy to provide detailed answers to customers’ queries.
