A4VTG71 Variable Plunger Pump with Steel Iron and Copper Construction, Half Year Warranty, and Drawing Available

Key features and positioning.
– Product positioning: The A4VTG series is a core component developed by Rexroth for high-pressure, heavy-load closed-loop applications (such as concrete mixer trucks, pumps, and other mobile machinery). The A4VTG71 is one of its typical specifications (displacement 71 mL/r).
– Key Features:
– Closed-loop design: The pump’s inlet and outlet ports are directly connected to the hydraulic motor, forming a closed oil circuit. This requires the use of an internal oil replenishment pump to replenish and cool the oil.
- High-pressure performance: Nominal pressure up to 400 bar (40 MPa), peak pressure up to 450 bar (45 MPa), suitable for high-load conditions.
– Variable control: Output flow can be continuously adjusted by altering the angle of the cam plate, with support for various control methods (such as HW hydraulic control and EP electric proportional control) to achieve precise control over speed and torque.
– Integrated oil replenishment pump: The built-in oil replenishment pump maintains a closed-loop system by replenishing leaked fluid and providing control over oil pressure. The maximum replenishment pressure is limited by an internal pressure relief valve.
Key technical specifications Parameter category A4VTG71 Typical specifications Displacement (Vg) 71 mL/rev (cm³/rev) Nominal pressure 400 bar (40 MPa) Peak pressure 450 bar (45 MPa) Control method Example HW (hydraulic proportional control, mechanical servo)
