Abstract

The invention relates to a pumping system for applying heat sensitive chemical liquids. It is known to use piston pumps to transfer liquid chemicals, for example to supply paint to spray equipment. The operation of some known piston pumps generates heat through friction where seals interface with cylinders or rods. It can be a problem that some chemicals, for example UV paint, are heat sensitive and so may be damaged by heat caused by the operation of the piston pump, or heat cured. The system comprises a fluid inlet, a piston pump having a piston, a first diaphragm pump having a first diaphragm and a load chamber, a second diaphragm pump having a second diaphragm and a delivery chamber, valve means, and a fluid outlet. The system is arranged such that a first stroke (for example, an upward stroke) of the piston causes the first diaphragm to create a vacuum to draw the fluid into the load chamber via the inlet, and the second diaphragm to drive the fluid from the delivery chamber via the outlet. A return stroke (for example, a downward stroke) of the piston causes the first diaphragm to drive the fluid from the load chamber into the delivery chamber, and the second diaphragm to displace the fluid from the load chamber into the delivery chamber, and the valve means opens and closes the load and delivery chambers.
