High capacity centrifugal sand gravel pump for dredging
Application
Gravel sand pump is designed for continuously handing the most difficult higher abrasive slurries which contain too big solids. The gravel sand pump is suitable for delivering strong abrasive slurry containing bigger particles in mining, explosive sludge in metal melting, dredging and so on. The advantages of the pump are heavy flow, easy installation and operation, good performance of NPSH and abrasion resistance.
Features
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 .
Applicable to: sand dredge pumping , dredge river, mining and transport metal smelting .Flow range: 36-3800 m 3 / h Head range: 3.5-80 m. Maximum through particle size: 254 mm .Maximum efficiency: 72% Cavitation allowance: 2-8 NPSH (r).
