Abstract: The present invention is a pump control and distribution system consisting of a pump and reversing flow control valve with a single-handle to control flow direction and flow rate of a liquid. The system can be operated at a rate of 0 to 300 gallons per minute and the flow reversed or stopped with a single motion of the operating handle. The flow rate of the liquid can be precisely controlled in either direction, along with the liquid pressure. This allows the use of a constant speed pump turning in one direction and gives the operator the ability to control the product transfer regardless of viscosity or volume. A purge valve connected to the outlet of the pump is used to remove substantially all retained liquid in the system after transfer of liquid is complete. The system can be mounted to a vehicle for delivery of bulk liquids.
