12/10G-G Horizontal Centrifugal Sand Gravel Mining Suction Dredge
Pump Single Casing
1.Introduction of CNSME® SG/250G (12/10G-G) Sand Gravel Pump:
SG Series sand gravel pumps are designed for continuous handling of
the most difficult higher abrasive slurry, containing solids too
large to be pumped by a standard slurry pump.
12/10G-G Sand Pump
1) Total Net Weight— 4450kg
2) Wet parts— Impeller (diameter: 864mm),Bowl, Back liner
3) Shaft seal— Packing seal, Expeller seal, Mechanical seal
Product features and application of the gravel sand pump:
1. the gravel pump is horizontal, single pump casing structure
centrifugal pump.
2. Use special clamp clamping pump body and pump cover, the pump
outlet can be adjusted in the any direction of 360 degrees, easy to
install and use.
3. The bearing components with cylindrical structure, easy to
adjust the gap between the impeller and the pump body to keep long
working life .
4. Bearing with grease lubrication.
5.Gravel pump has three kinds of shaft seal including packing seal,
vice impeller seal, mechanical seal.
6. Wide flow channel , good cavitation performance, high
efficiency, abrasion resistance.
7.Transmission methods are: V-shaped V-belt driven, flexible
coupling driven, gearbox transmission, hydraulic coupling driven,
thyristor speed control speed and so on.
8.Over-flow components Material: nickel-containing high-chromium
wear-resistant alloy.
9.Using variety speed and variants, making the pump running in the
best conditions .
10. Long working life and high operating efficiency can meet a
variety of bad working conditions.
