Impeller
Volute casing
The volute casing is made of wear-resistant and compression-resistant alloy(hardness≥56HRC,impact toughness≥8J/cm2).Advanced smelting technology combined with casting process and heat treatment process guarantees smooth casting surfaces and reliable internal qualiyt.
The bulge test will be carried out after molding,and the test pressure is 2 times of the discharge pressure of the pump.If there no leakage after 20 minutes,strength and tightness,strength and tightness pressure test reports can be issued.
Liner plate
The liner plates are made of wear-resistant high chromium alloy cast iron(hardness≥56HRC,impact toughness≥8J/cm2).
