Product Description

Parker P Series High-Precision Axial Piston Variable Pumps

Product Overview: The Parker P Series is a range of compact, high-performance axial piston variable displacement pumps designed for industrial and mobile applications requiring low-to-medium displacements (8cc to 31cc). This series is renowned for its exceptional control flexibility, featuring specific models like the P16VL-11-EP-T-10-S137-J, P16VMR-10-EP-D-20-S208-J, and P21VMR-10-CMC-20. By integrating advanced EP (Electric Proportional) or CMC (Constant Power/Pressure) regulators, the P series enables microsecond-level precision in flow and pressure modulation, making it the preferred choice for injection molding machines, small presses, CNC tools, and mini-excavator auxiliary systems.

Key Technical Advantages:

  • Advanced EP Control: Supports direct swashplate modulation via electronic signals, allowing for infinitely variable flow control to boost automation responsiveness and machining precision.

  • Ultra-Compact Architecture: The high-integrity cast iron housing provides a lightweight and small footprint, ideal for constrained Hydraulic Power Units (HPU) or compact mobile equipment.

  • High Efficiency & Energy Savings: Optimized valve plate and piston group designs minimize internal friction and leakage, ensuring peak volumetric efficiency at rated pressures.

  • Quiet Operational Environment: Structural noise-dampening treatments effectively suppress hydraulic pulsations, creating a significantly quieter workspace.

  • 100% Industrial Standard Compatibility: Manufactured to strict SAE and OEM specifications (e.g., S137, S208 special configs), ensuring mounting and porting align perfectly for a seamless “drop-in” replacement.

Detailed Models & Parameters:

  • Core Series: Parker P Series (P8, P16, P21, P31).

  • Model Keywords: P16VL-11, P16VMR-10, P21VMR-10, P8, P16, P21, P31.
