A4VG Hydraulic Charge Pump Rexroth Seal Replacement For Construction Machinery

Product Detail:

Many series of hydraulic piston pumps require a charge pump to compensate for internal leakage, maintain the pressure of the main circuit, provide oil cooling, compensate for leakage of external valves and auxiliary systems, and provide pressure oil for control.

There are many factors that determine the demand for charge flow and the selection of charge pump specifiions. These factors include: system pressure, pump speed, pump swash plate angle, oil grade, working temperature, radiator size, tubing length and diameter, control response characteristics, auxiliary system flow requirements, hydraulic motor types, etc.
