High Chrome Iron Sand Dredge Pump Centrifugal 8 Inch Dredge Pump
8 Inch Centrifugal Large Capacity Anti-Abrasive Sand Suction High Chrome Iron Material Sand Dredge Pump
Construction of Gravel Pump:
Construction of Gravel Pump is of single casing connected by means of clamp bands and wide wet passage. The wet parts are made of Ni hard and high chromium abrasion-resistance alloys. The discharge direction of punp can be oriented in any direction of 360 degree. This type of pump possesses the advantages of easy installation and operation, good performance of NPSH and abrasion resistance.
Material
The material for standard G series gravel pump is high-chrome alloy. This kind of material is very wear resistant and has excellent performance under erosive conditions. KmTBCr27: hard carbides within its microstructure provides higher abrasion resistance.
Type GH are high head pumps.

The advantage of G sand /gravel pumps
| 1 | Large drdging depth, high density of dredging mud, good NPSH and stronger suction lift ability |
| 2 | Strong through-put. The pump can persistently discharge gravel, high plastic soil lump and so on |
| 3 | The pump can be directly matched with either motor or diesel engine |
| 4 | Wide application. It can be used in various kinds of soil quality. |
| 5 | Little hydraulic loss, high efficiency and low oil-consumption |
| 6 | Little volume, light weight |
| 7 | Steady operating, little vibration, low noise |
| 8 | Simple & reliable construction, easily disassembly & assembly, convenient maintaining |
| 9 | Reliable sealing without leakage |
