Yuken P16 Series Axial Piston Pump | P16-A0-F-R-01 P16-A3-F-R-01 | Variable Displacement

The P Series axial variable displacement piston pumps by Chengyuan Hydraulic are high-precision units engineered for full compatibility with Yuken industrial standards. This range, featuring models such as P16-A0-F-R-01 and P16-A3, is specifically developed for industrial machinery where low noise and high energy efficiency are paramount. We utilize high-strength ductile iron housings and precision-hardened piston assemblies to ensure superior mechanical efficiency at continuous pressures of 21 MPa. As a premier interchangeable solution, every pump undergoes 100% simulated condition testing, ensuring that its pressure compensator response time matches the original OEM performance perfectly.

Key Technical Advantages:

• Ultra-Low Noise Technology: By optimizing the triangular decompression grooves on the valve plate and integrating damping orifices, the P16 operates with significantly lower noise levels than conventional pumps, improving the workshop environment.

• High-Precision Piston & Slipper Assembly: Piston surfaces are high-frequency quenched and mirror-polished. The slippers use wear-resistant bimetal materials, forming a stable hydrostatic oil film that minimizes friction at 21MPa.

• Agile Compensator Response: Equipped with pre-calibrated compensator springs, the variable mechanism can reduce displacement in milliseconds once the preset pressure is reached, saving up to 30% in energy by eliminating unnecessary overflow.

• Compact Single-Shell Structure: The high-strength lightweight pump body not only reduces overall weight but also enhances thermal dissipation, maintaining oil temperature stability during long-cycle operations.

Application Areas:

• Plastic Machinery: Variable power source for injection molding and blow molding machines.

• Precision Machine Tools: Hydraulic clamping and auxiliary control for CNC lathes and grinders.

• Industrial Presses: Pressure regulation circuits for small hydraulic presses and balers.

Expert Maintenance Tips:

• Drain Line Configuration: The case drain line must lead directly to the tank and be of sufficient diameter. Internal case pressure must not exceed $0.1\text{ MPa}$ to prevent shaft seal failure.

• Viscosity Maintenance: Recommended oil is ISO VG 32 or 46 anti-wear hydraulic oil. Keep operating viscosity within $20\text{–}200\text{ mm}^2\text{/s}$ to ensure the sensitivity of the variable mechanism.

• Priming Procedure: Before initial startup, fill the pump housing with clean oil through the drain port and rotate the coupling by hand to vent air. Never start the pump dry.
