slurry pump submersible

Slurry pumps can also simply axially adjust the clearance between the impeller and the adjacent throat casing sealing surface. This helps to maintain pump performance when internal components begin to wear.

The first major requirement for >slurry pumps is to provide adequate service life. The erosive and corrosive effects of slurries, such as the impact of high velocity flow of liquid/solid mixtures, can be really challenging. In many applications, some of the solids in the mixture are larger than the particles normally specified; therefore, the pump should be able to pass through them without causing any damage or operational problems.

A quench plan, as the name indicates, is designed to quench or cool the seal. It is normally used if short periods of dry running are expected. As illustrated bellow, the fluid is introduced into the area between the back of the seal faces and the close fit exit on the drive side of the pump.

To reduce component wear, most centrifugal slurry pumps run at fairly low speeds - typically less than 1200 rpm. Find the optimum position that allows the pump to run as slowly as possible but fast enough to prevent solids from settling out of the slurry deposit and clogging the lines.

Compared to standard centrifugal pumps, centrifugal pumps optimized for slurry pumping typically have the following features.

Firstly, analysing your duty helps us to determine whether you are using the type and size of pump best suited to your needs. Cavitation can occur due to surges; a very effective way to solve this problem is to install a choke on the pump head to increase the pressure on the casing, which then absorbs the surge, or to add a choke to the output to reduce the surge.
