Linde HPR 075 100 105 130 160 Accessories, Cylinder Block, Plunger, Swash Plate, Distribution Plate,

1. Product Overview

This product isThe complete set of core internal accessories for the Linde HPR series heavy - duty axial piston pumpsofThe complete set of core internal accessories. The HPR series pumps are known for their high pressure, high efficiency, and reliability, and are widely used in large - scale construction machinery, mining equipment, and industrial hydraulic systems. When the pump experiences internal leakage, reduced efficiency, or abnormal noise due to long - term use, replacing this complete set of core accessories is a key maintenance measure to restore its performance and extend its service life.

2. Core Features

• Complete set of precision components: It includes all key moving and sealing components inside the pump:

  • Cylinder block and pistons: They form the working chambers for oil suction and pressure, and their matching clearance directly determines the volumetric efficiency of the pump.

    
    

  • Swashplate shoes (Slippers): They connect the pistons and the swashplate, converting the reciprocating motion of the pistons into rotational motion. The matching between the ball heads and the piston sockets is crucial.

    
    

  • Valve plate: It is responsible for distributing high - pressure oil to the cylinder block holes and collecting low - pressure oil. Its surface flatness and wear resistance directly affect the pump's starting characteristics and impact resistance.

    
    

  • Return plate: It ensures that the slippers always cling to the swashplate, maintaining a stable oil film thickness and mechanical contact.

    
    

  
  

• High wear resistance and high precision: All accessories are made of high - strength alloy materials and processed with precision machining technology, ensuring wear resistance, fatigue resistance, and dimensional stability under extreme high - pressure and high - speed working conditions, and restoring the original performance of the pump.
