Rexroth A4VTG Hydraulic Pump | Variable Displacement Axial Piston Pump for Closed Circuit

The Rexroth A4VTG is an axial piston hydraulic pump belonging to the Rexroth A4VTG series, commonly used in closed hydraulic systems to efficiently convert hydraulic energy into mechanical energy.
Here is detailed information about this pump:
Core technical parameters
-Maximum work pressure:
-Continuous working pressure: 400 bar (megapascals)
-Peak pressure: 450 bar (megapascal)
-Working displacement: 90 cm ³/rev (with a displacement of 90 cubic centimeters per revolution)
-Working principle: As a hydraulic pump, its output speed is proportional to the input flow rate, and its output torque is proportional to the input hydraulic pressure.
-Applicable medium: hydraulic oil.
-Applicable temperature range: 30 ° C to 90 ° C.
-Installation form: flange installation .
Product Features
-Efficient and reliable: This series of pumps has a compact design, high efficiency, and the drive shaft can withstand radial loads with low noise.
-Static pressure transmission: Suitable for static pressure transmission in open or closed systems, it can provide stable torque output.
-Automatic alignment: The cylinder body and oil distribution plate adopt a spherical oil distribution design, which can automatically align during rotation, helping to improve efficiency and extend service life.
Application field
Based on its technical parameters and performance, the A4VTG90 hydraulic pump is widely used in equipment that requires reliable hydraulic drive, especially in the field of construction machinery, such as:
-Concrete pump truck: used to drive the boom system.
-Walking machinery: such as the walking drive system 1 of rollers, pavers, etc
