A10VO28DR52R Compatible Replacement Axial Piston Pump

The flow values above are theoretical family data and do not include volumetric losses. Permissible speed, pressure, fluid, inlet conditions, and control settings must be checked for the actual application.

What the Model Code Confirms

• A10VO: variable-displacement axial piston pump for an open circuit.
• 28: nominal size with 28 cm³ geometric displacement per revolution.
• DR: hydraulic pressure controller.
• 52: design series 52.
• R: clockwise / right-hand rotation.
• VSC12K68: configuration suffix that must be matched in full; do not approve a replacement from pump family and displacement alone.

Replacement Selection Checklist

Before confirming this pump as a replacement, compare the following items with the existing nameplate, hydraulic schematic, and approved dimensional drawing:

• Complete model code and any special index or suffix
• Direction of rotation
• Drive shaft profile and dimensions
• Mounting flange and pilot diameter
• Inlet, outlet, case-drain, and pilot-port arrangement
• DR pressure setting and system pressure-protection arrangement
• Required flow at the actual pump-shaft speed
• Inlet pressure, fluid, viscosity, filtration, and installation position
• Through-drive or rear-interface requirements, where applicable

Application Guidance

This pump should be considered only for open-circuit hydraulic systems whose pressure, speed, flow, mounting, shaft, port, and control requirements match the complete A10VO28DR52R-VSC12K68 configuration. Machine compatibility cannot be confirmed from an A10VO family name or nominal displacement alone.

Frequently Asked Questions

Is this an original Bosch Rexroth pump?

No. It is a POOCCA-compatible replacement product. The Bosch Rexroth model designation is used only to identify the replacement reference.

Can I replace another A10VO28 pump with this model?

Not automatically. The complete code, control type, rotation, shaft, flange, ports, settings, and rear-interface configuration must match the application.

What information should I send for confirmation?

Send the complete nameplate code, clear photos of the nameplate and all pump sides, required quantity, delivery country, and any available machine or hydraulic-system information.

Are the flow values actual delivered flow?

No. The listed flow values are theoretical values calculated from displacement and speed. Actual delivered flow is lower because of volumetric losses and depends on operating conditions.
