SANY Hydraulic Pump Seal Kit

Guide for purchasing hydraulic pump seals for excavators

1.The material of hydraulic pump seals should have high wear resistance, corrosion resistance, and high temperature resistance. Generally, materials such as polyurethane, nitrile rubber, and fluororubber are used.
2. The size of the hydraulic pump seal should match the structure and working conditions of the pump to ensure the sealing effect.
3.The sealing performance of hydraulic pump seals is a key factor in selection, and products with good sealing performance should be selected to ensure the normal operation of the hydraulic system.

The material of the excavator hydraulic pump seal should have high wear resistance, corrosion resistance, and high temperature resistance.
Commonly used materials include:
1. Polytetrafluoroethylene (PTFE): It has excellent wear resistance, corrosion resistance, and high-temperature resistance, suitable for high-speed, high-temperature, and high-pressure hydraulic systems.
2. Rubber: such as Nitrile rubber, FKM, etc., with good wear resistance and corrosion resistance, it is suitable for general hydraulic systems.
3. Polyether ether ketone (PEEK): It has excellent wear resistance, corrosion resistance and high temperature resistance, and is suitable for high-speed, high-temperature and high-pressure hydraulic systems.
4. Metal materials: such as stainless steel, titanium alloy, etc., have high wear and corrosion resistance, and are suitable for hydraulic systems under special working conditions.
The selection of suitable materials should be comprehensively considered based on factors such as the working conditions of the hydraulic system, the properties of the liquid medium, and the working environment of the sealing components.
