G (A) type dredging pump belongs to international advanced scientific and technological products. The pump adopts single-stage single-suction cantilever horizontal centrifugal pump with single pump shell structure linked by tape or screw. It has the advantages of light weight, good cavitation performance, strong abrasion resistance, wide passage, easy installation and use. It can continuously transport large particles of strongly abrasive mud and sand, and is suitable for dredging and dredging rivers by dredgers.

　　The pump is composed of pump head, sealing assembly, bearing assembly, bracket (or gearbox assembly), etc. The bearing lubrication mode is grease lubrication, thin oil lubrication.

　　The impeller, pump body, front guard plate and rear guard plate in the flow passage parts are all made of strong wear-resistant alloy cast iron or wear-resistant alloy steel with hardness no less than 58HRC.
