The Vaughan Conditioning Pump is a submersible chopper pump mounted on a portable stand and fitted with a high-velocity mixing nozzle. The Conditioning Pump recirculates the contents of wet wells by chopping and mixing to produce a homogeneous slurry that is more easily pumped out. Floating mats are removed and solids that have accumulated on the floor are re-suspended. The pump is mounted on a portable stand so it can easily be used in multiple locations at a single job-site, facility or municipality. Applications include: lift station conditioning, basin conditioning, influent station/channel conditioning, holding tank conditioning, and digester cleanout/homogenization.
