Send InquiryChat NowThe 12 / 10G-G gravel pump is a centrifugal pump with a horizontal, single-shell pump structure.
The pump adopts a single pump casing structure connected by a cassette, which is a single-stage single-suction cantilever horizontal centrifugal pump. It has the advantages of light weight, good cavitation performance, strong abrasion resistance, wide flow passage, and easy installation.
The bearing assembly adopts a cylindrical structure, which is convenient for adjusting the gap between the impeller and the pump body, and can be removed as a whole during maintenance.
It can continuously transport strong abrasive abrasive particles with large particles, and is suitable for dredging of dredgers and dredging of rivers.
Flow (Q): 100-420L / S, 360-1520m³ / h
Head (H): 11-58m
Speed (N): 400-850 rpm
Maximum efficiency: 60-72
Cavitation allowance (NPSH) r: 2-4.5
Suction caliber: 300mm
Outlet diameter: 250mm
Maximum passing particle size: 220mm
The 12 / 10G-G grit pump consists of a pump head, a seal assembly, a bearing assembly, a bracket, etc. The bearing lubrication method is grease lubrication.
The impeller, pump body, front shield and rear shield of the overcurrent parts are made of strong anti-wear alloy cast iron or wear-resistant alloy steel, and the hardness is not lower than 58HRC.

Use: Pump flow channel is wide, good cavitation performance, high efficiency, wear resistance. It is mainly used for continuous conveying of abrasive materials that are too large for general slurry pumps to convey. It is suitable for dredging, sand suction gravel, dredging rivers, river sand mining and metal smelting slag transportation.
