Vortex Wastewater Pumps

By A. W. Chesterton Corporation

Vortex pumps are primary sewerage pumps used to transport are sewerage through the wastewater treatment plant process. Because these pumps are required to handle the raw sewerage including grit and associated storm water runoff debris the abrasion rate is quite high. In this plant the pumps were lasting less than 1 year before severe abrasion caused reduction in tolerances leading to re-circulation. As the sewerage was no longer being efficiently transported to treatment the plants capacity was effectively reduced. Plant was considering replacement after 1 year a t a cost of $8,500.00.

As an alternative ARC ceramic composites were used to rebuild critical tolerances and a new abrasion resistant impellor design was installed. Afterwards a low maintenance Chesterton S10 cartridge seal was installed to improve pump life as well. Pump has been in service for over 36 months without failure.
