A hydraulic pump is a mechanical device that converts mechanical power into hydraulic energy. Hydraulic pumps work through displacement –  which is the amount of liquid transferred from a pump’s inlet to its outlet in one revolution or cycle.

During operation, it performs two functions. Mechanical action creates a vacuum at the pump inlet which allows atmospheric pressure to force liquid from the reservoir into the inlet line to the pump. Next, it delivers this liquid to the pump outlet and forces it into the hydraulic system. The flow generates enough power to overcome pressure induced by the load. 

Often, hydraulic pumps are used in high-pressure environments such as hydraulics and manufactured for a wide variety of systems.

Hydraulic Pump Repair Process

Failure of these critical parts of a hydraulic system can bring your systems to a stop or at least impair operation.  

We service the oil field as well as construction equipment, cranes, industrial equipment, rubbish trucks, belly/end dumps, and many more. We can also help and/or design just about any hydraulic system you would like to fabricate.

We are interchange specialists!  We first inspect the system to begin diagnosing the problem. Often, they will need to be disassembled and rebuilt during a repair.

If we can find the exact problem without tearing the unit down, we will let you know. We provide service on-site so you don’t have to wait. After your approval, the unit is cleaned and tolerances are re-verified.  We repair ALL TYPES of hydraulic components and cylinders. Our services include replacing chrome rod (we stock ½”-6” standard and 12mm-200mm metric material) and replacing all housing material, pumps, motors, valves, hoses, honing, line boring, glands, pistons, as well as all metric/standard cylinder repair.
