About Submersible Pumps

Submersible pumps are often used in sump drainage and other forms of dewatering. They are commonly used with the whole body of the pump under water, with the pump pushing liquid towards the surface rather than relying on creating a suction lift as would be the case with other centrifugal pumps. This makes them far more efficient when dealing with many applications. The impeller in such a submersible pump often pushes the water around the motor itself which does present the problem of effectively sealing the electronics away from the water flow. Audex Pumps are an example of submersible pump that works on this principle.

There are a number of basic challenges when using industrial submersible dewatering pumps in abrasive and tough applications. Impellers can quickly wear down and particles are often a problem for many submersible pumps as they can quickly clog the inlet. The Audex range almost entirely overcome this with a hardened chrome impeller to give a long lifespan and deal with any small but often abrasive particles travelling through the pump by using a sieve with hole sizes appropriate for the pump inlet. The next problem for submersible pumps is their seals. Audex uses double mechanical seals in oil baths and an elastomer volute liner both again for a long lifespan. This helps keep it a reliable solution to even aggressive applications while maintaining a low downtime working life.
