Hydraulic Piston Pump Parts & Replacement Components

High-performance replacement parts for variable-displacement axial hydraulic pumps and motors. Rivato Philippines supplies durable, OEM-compatible components to rebuild your pumps, restore pressure, and prevent machinery downtime.

Core Internal Pump Components

• Piston Shoes / Assemblies: Reciprocate within the cylinder block and maintain smooth sliding contact with the swashplate to generate fluid flow.

• Cylinder Blocks: House the piston assemblies under high pressure, maintaining tight tolerances to prevent fluid bypass.

• Valve Plates: Distribute high-pressure fluid flow in and out of the cylinder block with built-in anti-cavitation slots.

• Retainer Plates: Hold the piston shoe set securely in place against the swashplate during high-speed rotation.

• Swash Plates & Cradles: Control the piston stroke angle to regulate fluid displacement, output flow, and system pressure.

Applications

• Applications: Fits excavators, hydraulic power units (HPUs), industrial machinery, and heavy equipment pumps.
