Essential Parts We Repair on Your Hydraulic Piston Pump

The first step of repairing your hydraulic piston pump is disassembly. We take apart the axial piston pump for inspection and measurement, recording the dimensions of each part. Once we look through the entire unit and determine its issues, we prepare a quotation to give you an idea of what to expect.

When we get the go-ahead to move on with our repairs, we start by cleaning the unit. We lap the rotary parts and end cover, then make sure the bearing and shaft fit. Our technicians also ensure the pump’s play is within tolerance.

We make the appropriate repairs and replacements of critical parts, then reinstall the rotary components. After we complete the entire process, our specialists test the hydraulic piston pump. If it’s working at peak levels, we calibrate it, then send it off to painting and finishing. If it’s still not up to par, we go back and make corrections.

Repairing and replacing these essential hydraulic piston pump parts is a more economical solution than replacing the entire unit. Although the source of a pump’s failure can come from a multitude of sources, many fall into a few areas, such as:

• Piston assemblies: We service and repair broken and worn piston assemblies.
• Seals: We can swap the faulty seals for new ones.
• Swash plate: We also check and repair the swash plate using a lap machine, or we replace the plate if needed.
• Spring assemblies: We inspect and repair the unit’s spring assemblies.
• Bearing and oil seal replaced: We replace the bearing and oil seal every time, no matter the damage.
• Pressure and return ports: We inspect and repair the pressure and return ports within the pump.

In many cases, wear and tear cause problems. However, excessive heat, cavitation, extreme pressure and contamination can also cause premature failure of your piston pump. Another reason for failure is from incorrect installation — all of which we can fix on the spot.

We use sophisticated software, digital controls and integrated electronics to restore your company’s piston pumps. Kohinoor Hydraulic Pumps works with the increasing complexity of hydraulic systems. Our technicians can inspect, repair, test and calibrate a range of piston pump issues.

We break down the unit and deliver it to you in a “like new” condition.
