Frequently Asked Questions (FAQ) for Rexroth A4VSO Series Axial Piston Pumps (Control Variables)

1. What is the fundamental working principle of the A4VSO series pump?

The A4VSO series is a swashplate-type axial piston pump designed for open-circuit systems. Its flow output is proportional to the input drive speed and its displacement volume. The displacement is infinitely variable by adjusting the angle of the swashplate. It's known for its excellent suction characteristics, low noise, long service life, and high power-to-weight ratio. Multiple control options are available to meet various system requirements.

2. What are the common control methods for the A4VSO pump?

The A4VSO series offers a wide range of variable control methods. The most commonly used include:

• DR/DRG: Pressure Control (Constant Pressure)

• LR: Constant Power Control (Hyperbolic)

• EO/EO2: Electroproportional Control

Other available controls include FR (Flow Control), MA (Manual Control), EM (Electric Motor Control), HW/HM/HS/HD (Various Hydraulic Controls), and DS (Secondary Control for speed sensing).
