PGM-4X Internal meshing gear pump
The maximum working pressure of PGM-4X gear pump: 210bar (some models can be customized with higher pressure).Displacement range: 25cm3/rev to 125.3cm3/rev (for example, PGM4-4X/032RA11VU2 displacement is 32cm3/rev).Speed range: 500-3600rpm, optimize the performance of low-speed working conditions.
REXROTH internal meshing gear pump PGM-4X series is a fixed-displacement, high-efficiency hydraulic pump, suitable for variable-speed transmission devices and industrial scenarios that require a high number of load cycles, with low noise, low pulsation flow and sealing gap compensation technology and other advantages.
1. Core characteristics
Fixed displacement design
PGM-4X series is a constant displacement internal meshing gear pump, which realizes liquid delivery through gear meshing. The structure is simple and the quantification is accurate.
Low noise and low pulsation flow
The involute tooth edge gear tooth system is adopted, the long meshing length reduces pressure pulsation, and the operating noise is low, which is suitable for noise-sensitive environments.
Sealing gap compensation technology
Even under low-speed and low-viscosity oil conditions, high volumetric efficiency can be maintained by automatically adjusting the gap and reducing leakage.
Wide viscosity and speed range
It is suitable for a variety of viscosities (such as HFC hydraulic oil) and speed conditions, with high flexibility.
Modular combination ability
It can be used in combination with internal meshing gear pumps (such as PGF series), vane pumps, and axial piston pumps to form a multi-link pump system to meet complex hydraulic needs.
2. Technical parameters
Maximum working pressure: 210bar (some models can be customized with higher pressure).
Displacement range: 25cm3/rev to 125.3cm3/rev (for example, PGM4-4X/032RA11VU2 displacement is 32cm3/rev).
Speed range: 500-3600rpm, optimize the performance of low-speed working conditions.
Material: The shell is aluminum, the flange and cover plate are cast iron, and the seals are made of FKM (fluorine rubber), which is suitable for the temperature range of -20℃ to +100℃.
3. Typical application scenarios
Plastic processing machinery
It is used in the hydraulic drive system of injection molding machines and extruder to provide stable flow and pressure.
Automation equipment
Adapt to scenarios that require precise control such as robots and CNC machine tools.
Heavy machinery
Undertake high-load cycle tasks in metallurgical equipment and ship hydraulic systems.
Energy and environmental protection
Support accumulator liquid filling, wind power generation pitch system, etc.
