A2FO10/61L-PZP06 Rexroth A2FO Fixed Pump

Product Overview

The A2FO10/61L-PZP06 and related models (A2FO10, A2FO12, A2FO16, A2FO23, A2FO32, A2FO45, A2FO56, A2FO107, A2FO160, A2FO250) belong to the Bosch Rexroth A2FO series of high-pressure axial piston fixed pumps (bent-axis design, Series 6x/61). Designed for open-circuit hydrostatic drives, these fixed-displacement pumps deliver flow proportional to drive speed. Fully interchangeable with original Rexroth interfaces and performance (100% match), every unit undergoes 100% simulated operating condition testing. Ideal for mobile and stationary applications, the series features precision bent-axis technology, high power density, high overall efficiency and compact design.

2. Compact robust design and high starting efficiency: Small size and weight, excellent starting characteristics, with flow precisely proportional to speed.
3. Long-life bearings and high reliability: Supports high pressure peaks and high speeds, resistant to vibration for extended service life.
4. 100% simulated duty testing and full interchangeability: Exact match to original Rexroth interfaces and performance curves—true drop-in replacement with no modifications.
5. Fine size graduation and economical design: Wide range of displacements for precise open-circuit application matching with easy maintenance.

Application Areas

Main/auxiliary pumps in construction machinery, agricultural equipment, industrial hydraulic power units, cranes, rollers, mining machinery, marine systems and stationary open-circuit industrial drives requiring high-pressure fixed pumps.

Expert Maintenance Tips

Ensure the housing is correctly filled with oil and the case drain is connected before start-up to prevent dry-running damage. Use hydraulic fluid meeting recommended viscosity and cleanliness levels (ISO 4406). Periodically inspect seals and bearings; perform moderate-load break-in initially. Strictly observe maximum speed and inlet pressure limits. When replacing, verify the complete model code (including rotation direction, shaft, flange and port options) for full interchangeability. Refer to official Rexroth data sheets (RE 91401) for precise flow and torque data.
