Anti-Abrasive And Corrosion-Resistant Cr28 A49 For Dredging Boat Use Long Life Sand Dredge Pump

G Sand gravel Pump Features:
1. Easy to Disassembly and Installation, Convenient Maintenance
2. Good Performance on NPSH
3. Good Wear-resistant Performance, Long Service Time of Wet Parts:
4. Reliable Shaft Sealing Without Leakage

Impeller

The impeller generally has three vanes or five vanes and wide application range.It is made of wear-resistant high chromium alloy cast iron(hardness≥58HRC,impact toughness≥9J/cm2).The impeller is fixed on the pump shaft with double thread,and the thread tolerances are inspected according to the pitch diameter of thread.Disassembly rings are installed at the rear of the shaft sleeve to make maintenance eas

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).

Type GH are high head pumps.

1.Application

1)To extract mud and sand for ships,river dredging and mining.

2)For long -distance transmission of big partical or strong corrosive materials

that general slurry pump can't transport.
