Rexroth Gear Pump PGH5-30/125RE11VU2+PGH4-31/025RE11VU2 Easy Installation Low

Product Specification

Description:

The Rexroth Gear Pump PGH5-30/125RE11VU2 + PGH4-31/025RE11VU2 is a high-performance internal gear pump manufactured by Bosch Rexroth in Germany. This tandem pump design, consisting of two gear pumps of varying displacements, is suitable for hydraulic systems requiring two different flow rates. The PGH5-30/125RE11VU2 and PGH4-31/025RE11VU2 combination offers two different displacements to meet the needs of complex hydraulic systems. Both the PGH5 and PGH4 series are fixed-displacement gear pumps suitable for applications requiring high flow stability. With a maximum operating pressure of 350 bar, they meet the demands of high-pressure hydraulic systems. Optimized gear design and sealing technology ensure low operating noise and minimal flow pulsation, enhancing system smoothness.

Applications:

Construction Machinery: In construction machinery such as excavators, loaders, and cranes, this tandem gear pump can be used to simultaneously drive multiple hydraulic actuators. For example, one pump drives the travel motor while the other drives the hydraulic cylinder, enabling coordinated movement of the equipment's travel and working mechanisms.
Industrial Machinery: In industrial equipment such as injection molding machines, hydraulic presses, and automated production lines, tandem pumps provide precise flow and pressure control for various hydraulic circuits, improving production efficiency and product quality.
Plastics Processing Machinery: Suitable for plastics processing machines such as injection molding machines and extruders, providing power for hydraulically driven operations such as mold opening and closing, injection, and pressure holding.
Foundry Machinery: In foundry machines, this pump drives hydraulic cylinders and motors for operations such as pouring molten metal and opening and closing molds.
 

Advantages:

High Efficiency: The internal gear pump utilizes advanced sealing technology and an optimized gear mesh design to reduce internal leakage and improve the pump's volumetric efficiency.
Energy-Efficient Operation: Under low-load conditions, the tandem pump automatically adjusts flow based on actual demand, avoiding unnecessary energy waste. Durable Design: Constructed of high-strength materials, it withstands high pressures and loads, extending its service life.
High Contamination Resistance: Optimized seal clearance compensation ensures high efficiency even at low speeds and with low-viscosity fluids, while minimizing the impact of impurities on pump performance.
Low-Noise Operation: Optimized gear design and sealing technology effectively reduce operating noise, providing a more comfortable working environment for the operator.
Low-Pulsation Flow: The long engagement length of the involute tooth edges reduces flow pulsation and improves hydraulic system stability.
Versatile Combinations: All frame sizes and specifications are compatible with each other and can be combined with other hydraulic pumps, including axial piston pumps, internal gear pumps, and vane pumps.
Easy Installation: Multiple mounting options are available for easy integration into existing hydraulic systems.
Compatible with a variety of fluids: This pump is compatible with HFC fluids (seal design "W"), adaptable to a variety of working media.
Wide Viscosity and Speed Range: This pump maintains high efficiency across a wide range of viscosities and speeds.
