1. Product Overview

This product isLiebherr LPVD series axial piston pumpsofCore internal moving partsLPVD series pumps are widely used in high-pressure systems such as construction machinery and mining equipment. When a pump experiences internal leakage, decreased efficiency, or abnormal noise due to prolonged use, replacing this core assembly (cylinder block, plunger, and spindle) is the key maintenance method to restore its performance.

2. Core Features

• Precision fitThe cylinder block and plunger are fitted with high precision to ensure sealing and wear resistance under high pressure and high speed conditions; the spindle, as the core of power input, bears complex alternating loads, and its bearing positions and splines must maintain high precision.

  
  

• High wear-resistant materialThe cylinder block is usually made of high-strength alloy cast iron or steel, the plunger head is made of special wear-resistant material (such as copper-based or iron-based powder metallurgy), and the spindle is made of high-strength alloy steel and undergoes heat treatment such as tempering and high-frequency quenching to extend its service life.

  
  

• Recovery performanceReplacing worn cylinder blocks, plungers, and spindles can effectively solve problems caused by internal wear.Insufficient pressure, decreased flow rate, excessively high oil temperature, increased noiseThese issues significantly extend the service life of the pump.
