Using high-quality cyanide rubber, good sealing performance, no oil leakage, and long service life.
The use of high-strength gears has high hardness, wear resistance and high machining accuracy.
The of the pump adopts wear- phosphating process, which improves the hardness and has good wear resistance; it does not rust and has a beautiful appearance.
Main function: Generally used as a valve; mainly for pressure overload protection.
The hardness can reach HRC40-45, and the high-precision centerless grinding is used to the cylindricity of the shaft.
