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.
