Either an alternating or a direct current motor can be fur-nished and a suitable intake unloader is provided, assuringefficient regulation. In any case, the motor control is inaccordance with standard practice and specifications coveringthe type of motor used. Additional equipment includes an air receiver, safety valve, drain valves, pressure gage andservice valves to which air hose lines may be Portable Air Compressor with Capacity of 118 Cu. Ft. per Min. Efficient Rotary Piston Type Pump IN the design of the rotary piston pump manufactured bythe St. Louis Pump & Equipment Company, St. Louis,Mo., special attention has been given to the correction ofweaknesses most common to pumping devices used for han-dling volatile and non-volatile liquids. The pump is simple,
