Parameter Description of YUKEN Piston Pump A100-FR01BS-60

1. Model Code Explanation

• A100: Series identifier, representing the A-series variable displacement piston pump with a basic displacement specification of 98.5 cm³/rev (medium-to-large displacement type for medium-heavy duty industrial applications).
• F: Mounting type, indicating flange mounting (standard medium-heavy duty flange configuration, suitable for medium-to-large scale equipment installation and stable operation under medium-heavy load).
• R: Rotation direction, meaning clockwise rotation when viewed from the shaft end (standard rotation direction for YUKEN A-series medium-to-large displacement pumps).
• 01BS: Control type, referring to pressure-compensated variable control with enhanced sealing performance, which can automatically adjust displacement according to system pressure changes; the BS code indicates improved sealing structure and corrosion resistance, adapting to complex medium-heavy pressure working conditions.
• 60: Standard design number, corresponding to the standard configuration of the pump, matching the medium-heavy duty industrial application requirements and ensuring good compatibility with medium-to-large sized hydraulic systems.

3. Control and Adjustment Parameters

• Control Mode: Pressure-compensated variable control with enhanced sealing performance (Model 01BS), which can automatically reduce displacement when the system pressure reaches the set value, maintain stable system pressure, and the enhanced BS sealing structure improves the pump’s adaptability to complex media and prolongs service life under medium-heavy duty conditions.
• Pressure Adjustment: The pressure compensation range is 1.2-16 MPa; turning the pressure adjustment screw clockwise increases the set pressure, and the adjustment accuracy is ±0.25 MPa, which can be flexibly adjusted according to the actual working pressure requirements of medium-to-large hydraulic systems.
• Flow Adjustment: Realized through pressure compensation control; the minimum adjustable flow is 8.0 cm³/rev, and the flow adjustment response time is ≤45ms, which can quickly adapt to the pressure and flow changes of medium-to-large sized hydraulic systems.

4. Installation and Piping Requirements

• Mounting Type: Flange mounting (Model F), the mounting surface should be kept flat and clean, and the mounting bolts should be evenly tightened; it is recommended to use shock-absorbing gaskets to reduce vibration and noise during the pump’s medium-heavy duty operation.
• Shaft Alignment: It is recommended to use a medium-heavy duty flexible coupling to avoid bending or thrust stress on the shaft; the maximum permissible misalignment is less than 0.12 mm TIR, and the maximum permissible misangular is less than 0.2°.
• Piping Specifications: The inner diameter of the suction port pipe should be not less than 28 mm (1.1 inches) to ensure sufficient oil supply for medium-to-large displacement; the length of the drain pipe should be less than 1.2 m, and the pipe end should be submerged in oil; the pressure in the pump housing should be maintained at a normal pressure of less than 0.1 MPa and a surge pressure of less than 0.5 MPa.
