FAQ
▔▔
Is the A4FO Rexroth pump suitable for closed circuit systems?
No. The A4FO pump is designed specifically for open circuit hydraulic systems. For closed circuit applications, Rexroth A4VG or A4VSO series should be considered.
Can the A4FO pump replace my original Rexroth pump directly?
Yes, as long as the model code, displacement, shaft type, and mounting dimensions match the original pump, it can be directly replaced without system modification.
What hydraulic oil is recommended?
Mineral hydraulic oil according to DIN 51524 (HL, HLP) is commonly used. Other fluids may be supported depending on seal configuration-confirm before use.
How do I identify the correct A4FO model?
Check the nameplate on the original pump or provide the full Rexroth part number. If unavailable, operating pressure, flow rate, speed, and installation dimensions are required.
