Parameter Description of YUKEN Piston Pump A10-FR01BS-60

1. Model Interpretation

• A10: Series identifier, indicating the pump belongs to YUKEN A10 series piston pumps, which is a common small-sized variable displacement piston pump in the A series.
• F: Installation and structural feature, representing the standard flange mounting structure.
• R: Control type related identifier, associated with pressure compensator control system.
• 01: Control mode code, corresponding to pressure compensator control, which is a common control mode for YUKEN A series piston pumps.
• B: Pressure adjustment range code, indicating a specific pressure regulation range adapted to small-flow working conditions.
• S: Additional configuration identifier, related to sealing performance and auxiliary structure.
• 60: Design standard identifier, representing the European design standard (consistent with the coding rule of YUKEN A series 60-code models).

2. Core Technical Parameters

• Displacement: 10.0 cm³/rev (equivalent to SAE 10cc), which is the core characteristic of the A10 series small-displacement piston pump.
• Maximum Operating Pressure: Up to 21 MPa (3,045 psi), suitable for medium and low pressure hydraulic systems.
• Pressure Adjustment Range: 0.8 – 14 MPa (116 – 2030 psi), matching the pressure range corresponding to code “B”.
• Rotation Direction: Clockwise (CW), consistent with the standard rotation direction of YUKEN A series piston pumps.
• Shaft Type: Keyed shaft, ensuring stable power transmission.
• Port Location: Axial port, facilitating pipeline layout and installation.
• Mounting Type: Flange mount, in line with the structural feature of code “F”.
• Weight: 28.66 lbs (approx. 13.0 kg), lighter than the A37 series due to its small displacement design.

3. Suction & Drainage Parameters

• Permissible Suction Pressure: -16.7 ~ +50 kPa, ensuring stable suction performance and avoiding cavitation
• Drainage Pressure Requirement: Normal pressure ≤ 0.1 MPa; Surge pressure ≤ 0.5 MPa, protecting the pump’s sealing and internal components.
• Recommended Suction Pipe Inner Diameter: ≥ 12 mm (1/2 inch), matching the small displacement to ensure sufficient oil supply.

4. Control & Adjustment

• Control Type: Pressure compensator control, which can automatically adjust the displacement according to the system pressure to save energy.
• Pressure Adjustment: Turning the pressure adjustment screw clockwise increases the pressure; each full turn adjusts the pressure by 5.0 MPa (for A10 series with code “B”), adapting to the small-flow and medium-low pressure working conditions.
• Flow Adjustment: Turning the flow adjustment screw clockwise decreases the delivery flow; the minimum adjustable flow is 2.0 cm³/rev, and each full turn of the adjustment screw changes the flow by 1.2 cm³/rev, meeting the precise flow control requirements of small hydraulic systems.

5. Installation Notes

• Use a flexible coupling to avoid bending or thrust stress on the shaft; maximum permissible misalignment ≤ 0.1 mm TIR, maximum permissible misangular ≤ 0.2°, ensuring stable operation of the small-displacement pump.
• The length of the drain pipe should be less than 1 m, and the pipe end should be submerged in oil to prevent air from entering the pump and affecting the suction effect.
• When using steel pipes for suction or discharge ports, avoid excessive load from the piping to prevent excessive noise and vibration, which is more critical for small-sized pumps.
• The pump is preset to maximum delivery and minimum discharge pressure at the time of shipment; adjust according to the actual requirements of the medium-low pressure hydraulic system to ensure optimal performance.
