What We Repair

Hydraulic Pump & Motor Types We Repair

Hydraulic pumps are the heart of any hydraulic system. When the pump fails, the entire system goes down. General Engineering repairs all major pump types used in all types of industrial applications. Types include Gear, Vane, & Piston(Axial & Radial).

The most common pump type in high-pressure industrial systems. Axial piston pumps are used in excavators, presses, injection molding machines, and heavy equipment. We rebuild variable displacement and fixed displacement piston pump assemblies, including replacement of pistons, cylinder blocks, valve plates, swashplates, and rotating groups.

Hydraulic Pump Repair vs. Replacement Which Is Right?

Repair is typically right when:

  • The pump housing and major castings are structurally sound.
  • Failure is confined to internal wear components such as the rotating group, seals, or valve plate.
  • Repair cost is less than 40–50% of a replacement pump's cost.

Replacement may make more sense when:

  • The pump housing has cracks, severe erosion, or structural damage.
  • The pump is obsolete and internal parts are no longer available.
  • Contamination damage is so extensive that total rebuild cost approaches replacement cost.

Hydraulic Breaker Repair FAQ

Standard pump rebuilds are completed in 3–7 business days from receipt of the unit and approval of the repair quote. Pumps requiring special-order parts or with extensive damage may take longer we communicate lead times upfront.

Cost depends on the pump type, size, and extent of wear. A shaft seal replacement is far less expensive than a full rotating group rebuild. We provide an itemized written quote after inspection diagnostic evaluation is typically at no charge.

Yes. Pumps that have sat idle often develop dry-start damage when first operated again, and seals can degrade over time. We assess the extent of damage and provide a repair recommendation.

We can help you diagnose this. Symptoms like slow cylinder movement or low pressure can come from the pump, relief valves, or downstream components. If you bring in the pump, we will test it and tell you whether it is the source of your system problem.

Yes. Contamination damage is one of the most common failure modes we see. We rebuild contaminated pumps regularly. We will also advise on system flushing procedures before the pump goes back into service.
