Chicago Pump Swingfuser®

The Chicago Pump Swingfuser® family of aerator products have been installed in hundreds of wastewater treatment plants around the world for over 60 years. Units have been installed in aeration tanks, aerobic digesters, pre-aeration tanks, post-aeration tank, channels and Aer-degritter units.

These units have been designed to provide consistent, laminar flow at design air rates to minimize head losses throughout the unit as well as the associated power costs to overcome those head losses.

Standard materials of construction include cast iron tees and knee joint assemblies along with galvanized and stainless headers to provide long-term structural integrity of the units.
