ABSTRACT:
An air operated pump and motor unit with a rotor head assembly, an impeller head assembly, and a spacer tube unit disposed between these assemblies. The impeller head includes a pumping chamber and a liquid impeller assembly, and the rotor head includes a rotor housing, a cover assembly, and a rotor element. The rotor has a hub carrying a drive shaft and the rotor includes a plurality of radially extending blades and a spider unit joining the rotor hub to the blade carrier. The rotor hub and the spider lie adjacent the inner end of the housing and the carrier lies adjacent the cover, so that the rotor subdivides the rotor chamber into upstream and downstream chambers communicating with each other through passages in the spider. In use, the air passes from the upstream chamber to the downstream chamber through the openings in the spider and from the downstream chamber to the atmosphere.
