Abstract
An apparatus for pumping fluids comprises a suction pump and an inlet tube extendible into a container containing the fluid. A sealing plate is provided over the liquid surface to form a circumferential seal with the inner wall of the container and the outer wall of the inlet tube. The sealing plate prevents air from entering the lower part of the container and thereby prevents the pump from cavitating once the container is emptied. A pumping system is also provided wherein a plurality of pumping apparatuses is provided on a frame. A dispensing system is also provided wherein a plurality of computer controlled nozzles are each connected to a respective pumping apparatus whereby specific volumes of desired fluids can be dispensed.
