The RD1 uses Charles Austen's revolutionary patented rotary diaphragm pumping principle. Giving extremely high performance from a compact unit, the unique reinforced diaphragm provides ten times the service life of a peristaltic pump.

The RD1 has no valves, no clogging and will even pump jellies and dissolved solids. Its self-priming and reversible pumping action is also suitable for both hot and cold liquids, making it a versatile pump suitable for a range of applications.
