A.Y. McDonald 6195-003, Model 325075SL, Air Powered Pump-SludgeMaster, 3" NPT Discharge, Aluminum

A.Y. McDonald Air Powered Pump-Sludgemaster

The SludgeMaster air powered pump is to be used for immediate use: simply hook up compressed air supply, lower through manhole or into sump or fluid to be pumped. No fuel tanks to run empty, no gas cans to carry, no electrical connections, no electric motors to overload. High capacity, low head operation to meet nearly every emergency or daily-use application. Keeps pumping without clogging on most problem jobs. Won’t choke up on small trash. Can run dry with no damage. Self-draining to prevent damage in below freezing weather. Sturdily built for rough handling and long-life endurance on land, at sea or offshore: cast iron & steel for wear, aluminum for weight-saving. 

-To accurately determine air consumption, please refer to the attached brochure to review curve. 

-Use a compressed air pressure supply between 60-100 psi for the best performance of the pump.
