What is Gravel pump?

Views:1     Author:Site Editor     Publish Time: 2020-07-13      Origin:Site

Gravel pump is a single-stage, single-suction, cantilever, horizontal centrifugal slurry pump. It is mainly used for the

transportation of strong abrasive materials that are too large to be transported by the slurry pump, such as granular coal transportation and digging. Mud dredging, river dredging, mining and metal smelting blasting, and transportation of root crops. The pump is especially suitable for high flow, high concentration, high lift conditions, and has good cavitation performance and abrasion resistance.

Gravel pump Performance characteristics:

① The high-strength bracket and cartridge bearing assembly are bolted for easy installation and removal and easy to adjust the impeller clearance. The water outlet can be installed at any angle and is easy to maintain.

② Over-flow parts such as pump body, impeller, front and rear guard plates are made of high-chromium anti-wear alloy material to ensure service life.

③ The single pump casing and wide flow channel design ensure the passage of large particles, good cavitation performance and strong anti-abrasive ability.

④ Packing seals or counter impeller seals can be selected according to different needs.
