A variety of factors must be considered to ensure a satisfactory service. Here are tips for choosing the right , pump, .xa0, In applications ranging from processing to wastewater treatment, plants often have to handle slurries. Handling this mixture of liquids and solids can be challenging and difficult. Some of the key factors in slurry pumping are the size and nature of the solids in the liquid and the type of wear they cause. Another is the corrosiveness of the liquid or mixture.

Natural rubber is an excellent wear material when handling wet sand slurries. Its strength, resilience and cut resistance have a positive impact on the wear performance of slurry pumps.

Compared to standard centrifugal pumps, centrifugal pumps optimised for slurry pumping usually have the following features.

Slurry pumps with rubber lining are the ideal pump for the mineral sand industry. They have a special rubber lining that makes them heavy duty pumps capable of withstanding high levels of abrasion.

Non-settling slurries consist of very fine particles that do not settle to the bottom of the pipe and do not settle for very long (i.e. weeks).

The basic mechanical seal flushing programme is very simple. It requires that a clear/clean fluid (usually water) is introduced into the space between the actual seal and the impeller side outlet restriction. The flushing fluid is introduced at a pressure higher than the pumping pressure, thus ensuring positive outflow/flushing of the mechanical seal and a clean operating environment.
