Rexroth A22VG Size 45 Variable Double Pump for Closed Circuit Hydrostatic Drives:
Nominal Pressure: 380 bar
Maximum Pressure: 420 bar
Features:
Variable double pump with two axial piston rotary groups of swashplate design.
Designed for hydrostatic drives in a closed circuit.
Flow is proportional to drive speed and displacement.
Flow can be infinitely adjusted by varying the swashplate angle.
Smooth flow direction change through the neutral position of the swashplate.
Single shared port for case drain fluid for both circuits.
Compact design suitable for tight installation conditions.

The A22VG piston pump is an efficient, compact and reliable solution designed for a wide range of demanding hydraulic applications. It features an axial piston variable displacement twin pump design that excels in closed hydrostatic drives, providing optimal performance in a variety of environments.
Its innovative swashplate design enables precise flow control proportional to drive speed and displacement. Adjusting the swashplate angle allows seamless and infinite flow adjustment to meet specific hydraulic requirements. The pump’s smooth transition in flow direction in the neutral swashplate position enhances hydraulic system stability.
The Rexroth A22VG hydraulic piston pump features a compact footprint and high-pressure seal design that integrates a shared case drain port for both circuits. This streamlined design is ideal for installations with limited space and ensures reliable operation and leak-free performance even in harsh conditions.
