Especially when the dredging depth reaches 20m or more, the above situation will be more obvious. The use of underwater pumps can effectively improve the above situation. The lower the installation position of underwater pumps, the smaller the suction resistance and vacuum, which can obviously reduce the losses during the work and improve the working efficiency. The installation of underwater pump can effectively increase the dredging depth and improve the ability to transport sediment.

Fine-grained sand can be extremely abrasive and typically wears slurry pumps quickly. Characteristics of coarse aggregates that can affect pump performance are size, shape and surface texture, as well as gradual changes in particle size, while fine materials can create excessive friction in the pipe.

In this article, we will present practical guidelines and rules for slurry centrifugal pumps. We will also discuss key operating characteristics, material selection and other considerations.

From an operational point of view the stuffing box is different as it requires some leakage to ensure lubrication and to prevent heat build up. The mechanical seal box should be leak free.

Types of slurry pumps

Submersible slurry pump pumps offer many advantages over dry and semi-dry (cantilever) mounted pumps.
