Paper Information :

Submersible wastewater pumps in the 2-8 kW range are mature products typically consisting of a close-coupled pump and induction motor integrated in a enclosure that can withstand continuous submergence. Different pump technologies are used and these products have typically been on the market for some 10-20 years with little or no design innovation.

Small wastewater pumps are commonly found in duplex wastewater pump stations in sewage collection systems and at wastewater treatment plants at municipalities and private operators around the world. Pump station design code ensuring adequate capacity for peak flow situations always leads to a significant oversizing of the pumps resulting in excessive energy usage and unnecessarily high equipment wear.

By employing an increased level of component integration it is possible to add a variable speed drive and specialty software inside the enclosure of a submersible wastewater pump. This technological breakthrough might seem small, but when explored in depth several valuable pump system functions and customer values can be derived. Examples are electrical control panels which are up to 50% smaller, energy savings up to 70%, pump sump cleaning costs reduced by up to 80 % and an inventory reduction of up to 80%!

Add to this remote communication capability, SCADA connectivity and data management.

The technical possibilities and functional values identified in this technology development have been verified in prototype installations, pilot project and at customer sites.
