ABS Process Fluid Aeration
Application: Aeration of Process Fluids
Pump Details: 115hp ABS Channelaire
Pump Type: Submersible Aerator
Wastewater, which tends to be very corrosive and abrasive, must be cleaned before being discharged into lakes or rivers. Aerators are used to inject air into the liquid to sustain biological growth, enabling bacteria to eat oil and other contaminants in the wastewater.This 115hp aerator experienced abrasive wear of its 316 stainless steel channel ring and motor mount when wastewater entered the motor and shorted the stator. Hydro rewound the stator, weld-repaired the channel ring and motor mount, and installed new cable entry assemblies. In addition, Hydro provided O-rings, grommets, lubricants, upper and lower seal assemblies, upper and lower bearings, a new impeller wear ring and a leak sensor for the junction box.
After checking the sensors and performing a no-load motor test, Hydro returned the repaired unit. Total cost of the repair was only 28% the price of a new unit. The unit was delivered in half the time it would have taken a new unit to arrive.
