FAQ:

What are the key specifications of the A4VSO series?

• Common Displacement Specifications (ml/rev): 40, 71, 125, 180, 250, 355, 500, 750.

• Nominal Pressure: 350 bar.

• Peak Pressure: 400 bar.

• Bearing: Features a specially designed, long-life, high-precision full roller bearing.

• Shaft: Through-shaft design allows for mounting additional pumps to form a multi-pump group.

7. What should be considered during commissioning and adjustment?

• Alignment: Ensure the coupling between the pump and motor has a gap of 3-5 mm to avoid thrust load on the pump's bearing, which could cause damage.

• Filling & Venting: Before starting, fill the pump casing with clean hydraulic fluid through the drain port to vent air. The drain line should be connected to the highest T port on the pump.

• Rotation Direction: Confirm the pump's specified rotation direction (viewed from the shaft end) and ensure the motor rotation matches. Incorrect rotation can damage the pump.

• Minimum Flow Setting: If the pump's minimum displacement is set too large, it may become impossible to lower the pressure setpoint by adjusting the control valve.

• DP Control Setup: For DP controls, the pressure differential across the pump's DP valve is the sum of the pre-set pressure differential on valve 2 and the differential set on valve 5 (at minimum pump displacement), typically set to a standard sum of 33 bar.

8. In which industries are A4VSO pumps commonly applied?

A4VSO pumps are widely used in high-pressure, heavy-duty industrial applications. Common industries include: ceramic presses, refractory material presses, steel and forging equipment, metallurgical machinery, mining machinery, marine machinery, petroleum equipment, engineering machinery, and machine tools.
