Hydraulic Pump Rebuild - Spare Parts and Seal Kits

Hydraulic pumps operate under immense loads and pressures, which inevitably leads to the natural wear and tear of their internal components. Replacing worn hydraulic pump parts is a proven way to restore your machine to full working order, often costing just a fraction of a brand-new unit. However, the key to a successful rebuild is using high-precision aftermarket replacements or OEM parts that can withstand the harsh conditions of construction and agricultural machinery.

Most Common Wear Parts in Piston Pumps

In fluid power systems, elements subjected to continuous friction degrade the fastest. In our warehouse, you will find all the necessary components for a complete pump overhaul:

• Pistons with shoes: The main working elements in axial piston pumps, responsible for displacing the oil.

• Cylinder blocks (barrels): The components housing the pistons, requiring a perfectly smooth surface.

• Valve plates and set plates: Crucial for maintaining proper pressure, sealing, and swashplate angle in variable displacement pumps.

• Seal kits and O-rings: Comprehensive repair sets to prevent external leaks and internal pressure drops.

• Drive shafts and bearings: Responsible for transmitting torque from the engine to the pump assembly.

How to correctly identify pump parts?

To select the right spare parts for a hydraulic pump, you must check the pump's specific nameplate (not just the machine's model). It contains the exact model, series, and part number. Keep in mind that excavators or loaders from the same production year could have been equipped with entirely different pump versions from the factory. If you have any doubts, send our technical team a photo of the nameplate, and we will compile the exact repair kit you need to bring your machine back to life!
