How does a dredge pump work?

As the slurry is collected at the bottom of the tower, more rubber lined pumps are required to transfer the slurry to storage tanks, tailings ponds, waste treatment facilities or filter presses. Depending on the type of FGD process, other pump models are available for slurry discharge, pre-scrubber recovery and catch basin applications.

The impeller is considered the heart of the dredge pump and is similar to a fan that expels air and creates centrifugal suction. At the suction pipe, this vacuum absorbs the slurry and transports the material through the discharge line.

It is often used if a short period of dry running is expected. Fluid is introduced into the area between the back of the seal face and the tight-fitting outlet on the drive side of the slurry pump.

- Hydraulic efficiency is as important as the material, as efficiency is related to wear. The swept-back design of the impeller blades minimises the separation of solids from the carrying fluid, resulting in a more uniform flow. This results in a slower wear rate.

As described below, there are several >types of pumps that are suitable for pumping slurries. However, before considering which technology to use, we must address several key issues.
