• 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

• 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
• Filling & Venting: Before starting, fill the pump casing with clean hydraulic fluid through the drain port to vent air
• Rotation Direction: Confirm the pump's specified rotation direction and ensure the motor rotation matches
• Minimum Flow Setting: If the pump's minimum displacement is set too large, it may become impossible to lower the pressure setpoint
• DP Control Setup: For DP controls, the pressure differential across the pump's DP valve is the sum of the pre-set pressure differentials

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