Bosch Rexroth Series F 2010 Technical Manual – What You Need on the Bench

You’ve got a Bosch Rexroth Series F 2010 Technical Manual on the bench and you’re staring at a worn shaft seal on an AZPF pump. Without the right documentation, that pump goes back together with guesswork – and guesswork costs you a second teardown. This is the factory manual from 2010, 68 pages, no aftermarket reprint. It covers the Series F external gear pumps with displacements from 4.0 to 28 cm³/rev. Let me tell you what’s actually in it and how it keeps you from making expensive mistakes.

Construction and Axial Compensation – What the Manual Covers

Page 2 breaks down the construction of these pumps: a pair of gears in bearing bushings, a case with front and rear covers, and the drive shaft sealed by a shaft seal ring. The manual explains the axial compensation system – internal sealing proportional to delivery pressure, controlled by operating pressure admitted to the back of the bearing bushings. If you don’t understand that zone, you’ll chase leaks forever. The diagrams show the sealing zones and the forces involved. That’s page 2, and it matters because the radial clearance at gear tips is sealed by internal forces pushing them against the case. Miss that detail and you’ll get internal leakage you can’t diagnose.

Ordering Code: How to Identify Your Pump

The ordering code section on page 4 covers single pumps, page 5 covers multiple pumps. Each variant gets a specific code – for example, AZPF-… You need the correct code to order service parts like the Manual Transmission”>Manual Transmission components? No. But you need it to match the drive shaft, front cover, and line port configurations. The manual lists six drive shaft options, multiple front covers, and line ports in connection flange or screw thread. If you order a seal kit without confirming the ordering code, you’re wasting money.

Performance and Noise Charts – Real Data on Page 16

Page 16 gives specifications: nominal pressure 280 bar, slide bearings for heavy duty, gears with 12 teeth to minimize flow pulsation. But the real meat is in the performance charts starting page 11 and noise charts page 14. You can look up exact flow rates at given pressures and speeds. Need charge pressure? Page 16. The manual also defines direction of rotation and definitions of pressures – something aftermarket manuals get wrong all the time. I’ve seen techs install pumps backwards because they trusted a third-party wiring diagram. This is OEM data, not a translation error.

Unit Dimensions: 30+ Variants Cataloged

Starting on page 20, the manual lists dimensional drawings for over 30 standard pump variants: A 510 240 021, A 510 241 021, A 510 840 309 / 315, and many more. Each variant has its own mounting flange dimensions, shaft extension lengths, and port locations. If you’re retrofitting or replacing a pump in a machine, you need the exact drawing to verify clearance. Page 20 to page 57. No guessing – you measure off the factory print.

Does This Manual Cover Integral Valves?

Yes. Page 10 covers gear pumps with integral valves. It also includes design calculations for pumps and drive arrangements. Multiple gear pumps through drives are covered starting page 19. That’s important if you’re dealing with a tandem or triple pump setup. The manual shows how the drive torque transfers and which shafts can handle it.

Notes for Commissioning – Page 59

Page 59 is where you find the commissioning and maintenance notes. This is not filler. It tells you how to prime the pump, what to check for before first startup, and which service parts are critical. Service parts list starts page 60 – includes seal kits, bearing bushings, and shaft seal rings by ordering number. Fittings start page 62. The manual ends with the AZ configurator on page 64 for ordering complete replacements.

Is this manual specific to the AZPF series only?

Yes. It covers the Series F external gear pumps (AZPF-…) with displacements 4.0 to 28 cm³/rev. It does not cover the B, N, G, S, T, or U series. If you have a different series, you need the corresponding manual.

Can I use this manual for troubleshooting a pump that’s already installed?

Page 59 gives commissioning notes that include checks for direction of rotation, pressure settings, and contamination. The performance charts on pages 11-14 let you compare actual flow/noise to factory specs. If your pump is making noise or losing pressure, you can cross-reference the noise charts to identify abnormal frequencies. The section on axial compensation also helps diagnose internal wear. For service parts, the ordering numbers on page 60 let you order exact replacements. This manual is the primary troubleshooting tool for these pumps – assuming you also have the machine’s hydraulic schematic. The schematic is not included. But the pump-specific data is complete.
