This was part of a warehouse clean out. It was on the shelf in the parts room. It has the power cord cut, which leads me to believe that they saved this from another piece of equipment.... I do not have a way to test this unit, but the pumps do "pump" when the shaft is spun manually. 8Hdm-10-M850X compressor pump untested 110/220 volts M850GX GE 2hp 50hz. Condition is "For parts or not working". Shipped with USPS Parcel Select Ground. Please examine the pics for condition and quality.
