Gorman-Rupp self-priming centrifugal power take-off pumps are ideal for handling aircraft fuels, fuel oil, gasoline and other petroleum derivatives. These pumps have no check valve which provides better suction performance when handling solvents, petroleum products and similar liquids. O Series PTO pumps can also be used for water wagon applications. The pump volute and impeller are offered in lightweight aluminum with a bronze replaceable wear ring. Helical gears provide quiet operation. These units are available with left or right hand rotation. Designed for truck mounting.
