ABSTRACT:
Apparatus for pumping a flowable material from a tank disposed on an engine-powered vehicle is the subject of the present invention. The invention is particularly adapted for use with a multiple compartment tank on a petroleum delivery truck. An air pump, which may be the air pump for operating the air brakes of the vehicle, is powered by the vehicle engine and pumps air into a surge tank where the air is held under pressure. A conduit leads from the surge tank to a manifold that is coupled with each of the compartments of the material storage tank. Each of the compartments is coupled with the common manifold through appropriate spur conduits. Appropriate pressure regulator means maintains the pressure on the surge tank and valve means is operable to pass the air under pressure from the surge tank to one or more of the compartments thereby pumping the material from the storage tank.
