Spare Parts for PV270 Pump (Detailed Overview)

1. Core Components

• Piston: A critical moving part that directly impacts the pump’s displacement and pressure output.

• Retainer Plate: Supports the pistons and ensures stable reciprocating motion.

• Port Plate: Distributes hydraulic fluid flow to enable suction and pressure functions.

• Cylinder Block: Houses the pistons and forms sealed working chambers.

• Pump Liner Set: Protects the cylinder block and reduces wear.

• Piston Sleeve: Works with the piston to form a sliding friction pair.

• Vane(if applicable in pump design): Used for flow regulation in variable-displacement pumps.

2. Seals and Auxiliary Parts

• Shaft Seal: Prevents hydraulic fluid leakage and protects the pump shaft.

• O-Ring: Used for static sealing to stop fluid escape.

• Gasket: Fills gaps in flange connections to ensure tightness.

• Bearing: Supports pump shaft rotation and reduces friction.

• Drive Shaft: Transmits power to the pump’s internal components.

• Rotor & Stator Set(if applicable): Controls flow in variable-displacement pumps.

3. Technical Features & Compatibility

• Material: High-strength cast iron or steel for wear resistance and pressure tolerance.

• Compatibility: Designed to strictly match PV270 pump specifications (e.g., displacement, pressure rating) for direct replacement.

• Performance Optimization: Some parts (e.g., port plates, pistons) use advanced technologies like pre-compression volume design to reduce flow pulsation and enhance pump rigidity.

4. Applications

• Construction Machinery: Driving systems for excavators, road rollers.

• Agricultural Machinery: Hydraulic steering or drive systems for combine harvesters, forage harvesters.

• Industrial Vehicles: Lifting systems for forklifts and stackers.

• Specialized Equipment: Heavy-duty braking in mining machinery or drilling platforms.

5. Maintenance Recommendations

• Regular Replacement: Replace seals and wear parts based on operating hours or fluid cleanliness.

• Fluid Management: Use L-HM32, 46, or 68 low-freeze, high-pressure anti-wear hydraulic fluid. Maintain oil temperature at 15–65°C and kinematic viscosity at 27–43 mm²/s.

• Cleanliness Control: Keep fluid cleanliness within NAS 10 grade to prevent accelerated wear from contaminants.
