Alatas Houston recently performed a Rexroth A4VSO-355 pump repair after the client suspected poor efficiency. The work took place at the Alatas Houston workshop and was started with a free disassembly and inspection of the client’s Rexroth A4VSO.
Once completed our engineers produced a report and quote which the client then approved. This Rexroth pump required the following replacement parts work:
- rotary group complete with pistons
- all bearings
- seals
- lens plate
- new shipping plates/caps/plugs
The unit was then re-assembled as per Rexroth’s requirements with the new spare parts in place. Next, our engineers at Alatas Houston tested the A4VSO-355 pump unit on our state of the art test stand, where we measured its efficiency. All Rexroth units need to achieve a 96% efficiency or better before being handed back to the customer.
After the repaired Rexroth A4VSO-355 pump passed the efficiency test, our engineers set the unit as per the hydraulic schematic provided by the customer for a plug and play operation.
We completed the work by painting the unit and prepping it for delivery. We also send the complete repair and test reports of the unit’s performance to the client along with our one year repair warranty.

Our Houston workshop and others around the globe are ready to assist you with inspections and repairs. Please contact us to find out more.
