FAQ:

When multiple pumps with standard DR controls are set to the same pressure and run in parallel, slight inherent differences in their response characteristics and pressure settings can cause them to not reduce displacement (cut off) at exactly the same time and rate. This lack of synchronization can lead to interactions between the pumps, resulting in pressure fluctuations and potentially causing severe pipeline vibration.

6. 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.
