Swanson Reman / Exchange Program

Components may be exchanged for remanufactured replacements that save our customers time and money. All replacement pieces are 100% tested to ensure OEM performance.

Reman and Repair Expertise for Hydraulic Pumps, Motors and Valves

A failing pump can quickly damage your entire hydraulic system, including valves and cylinders. Pumps can be remanufactured or repaired at Swanson’s facilities worldwide.

Swanson remanufacturers and repairs the full spectrum of valve types used in diverse hydraulic fluid applications.

Hydraulic motors are remanufactured to industry standards at a lower cost than new equipment using OEM and rebuilt parts.



Our test bench operates repaired and remanufactured pumps and motors at the rated RPM and tests for volumetric efficiency, leakage and sound levels. Back pressure is applied to simulate the pump or motor work load and pressure ratings. Swanson testing procedures identify a number of potential hydraulic pump, motor and valve performance problems. Potential failure causes, such as cavitation, over-pressurizing, over-speeding, underperformance and high system temperature failures are identified. All components are repaired and remanufactured to industry standards at a lower cost than new equipment using new OEM and remanufactured replacement parts.
