Anfield VPA10V(S) Series Variable Displacement Axial Piston Pumps

The Anfield VPA10V(S) series is designed for open loop hydraulic circuits, suitable for both mobile and industrial applications. The flow is proportional to the drive speed and displacement, and the flow rate can be infinitely adjusted by altering the swashplate angle.

Key Features:

• Displacements: Ranges from 1.10 in³/rev (18 cm³/rev) to 8.54 in³/rev (140 cm³/rev).
• Speed: Up to 3,300 rpm.
• Pressure: Rated working pressure of 4,000 psi (280 bar), with a peak of 5,000 psi (350 bar).
• Mounting: Available in SAE or Metric mounting with side or rear porting.
• Controllers: Available with various controllers (e.g., pressure, flow, and power control) with short control response times.
• Design: Nine-piston, low noise design offering excellent suction and long service life.
• Through Drive Capability: Supports multi-circuit systems and full power through drive.

Benefits:

• Provides power only when needed through variable displacement.
• Flexible installation options with multiple case drain ports and mounting orientations.
• Long service life and favorable power/weight ratio.
• Available with Buna-N or Viton seals.

Control Options:

• DR – Pressure Controller: Maintains maximum pressure within the control range.
• DRG – Remote Pressure Controller: Remote-controlled pressure limitation with separate valve.
• DFR/DFR1 – Pressure and Flow Controller: Varies flow based on pressure.
• DFLR – Pressure, Flow, and Power Controller: Regulates pressure, flow, and power to maintain constant torque.

Technical Data:

• Input Pressure Range: 11.6 psi (0.8 bar) min to 435 psi (30 bar) max.
• Nominal Output Pressure: 4,000 psi (280 bar), Peak Pressure: 5,000 psi (350 bar).
• Case Drain Pressure: Max 30 psi (2 bar) above inlet pressure.

Installation Notes:

• Ensure pump housing is filled with fluid during commissioning.
• Use flexible couplings for connections to minimize noise.
• Vertical Installation: Ensure fluid levels and pressure conditions are met.
• Horizontal Installation: Position ports to ensure proper fluid intake and pressure control.

Through Drive Mounting:

• Option for adding multiple pumps up to the same size (100% through drive).
• Torque Limits: Maximum input and through drive torques should not be exceeded.

The Anfield VPA10V(S) pumps offer versatile, high-performance solutions for hydraulic applications, with customizable controls, high efficiency, and reliable operation in various system configurations.
