It's the inner values that counts!

Do we have an efficient pump solution for highly dynamic processes?

Of course, our efficient, modularly combinable internal gear pumps.

Internal gear pumps from Bosch Rexroth are highly efficient and versatile all-rounders. This compact, robust, and quiet type of positive displacement pump delivers consistently high efficiency levels – for many, many years. The key to this is the compensation of unwanted leakage in both axial and radial directions. Our design countermeasures automatically optimize the gap dimensions between the internal gear, ring gear, and housing. This ensures the fluid is conveyed continuously, with low pulsation, and with minimal leakage losses. The result: minimal wear, maximum volumetric efficiency.

Further advantages:

• Ideal for dynamic and variable-speed applications: High efficiency over a wide speed range thanks to a symmetrical design and low moment of inertia.
• Long service life: Optimal material composition and continuous improvement of manufacturing processes.
• Modularity: Our cross-design pump combinations open up completely new options for tailor-made solutions. This is how you find the optimal pump for every requirement – typical of Bosch Rexroth.

Do we offer compact pump solutions for high pressure, high speeds, or frequent load changes?

Absolutely! Simply combine our internal gear pumps with other pump types for more power and energy efficiency.

Our internal gear pumps are not only versatile on their own. When combined with other pump types, they create entirely new solution options for individual applications – especially those involving high pressure, high speeds, or frequent load changes. The compact PGH55 model, for example, is very popular. This robust and quiet double pump features a short design and impresses not only with its constant, low-pulsation displacement volume but also with its wide viscosity and speed ranges. The flexibility is almost limitless: all designs and nominal sizes can be freely combined with each other, including with other internal gear pumps, vane pumps, or radial piston pumps.
