Pumps with two diaphragms or membranes, which by the action of compressed air, pumping the liquid produced thanks to a game of ball valves available to them.
They are constructed of plastic materials: PP and PVDF and Stainless Steel..
The membranes in: Buna, PTFE, XL, FPM or EPDM.
Pumps lower performance than the Seria DIA and lower cost. Self-priming pumps without bearings, without mechanical seal, no oil, no electric motor (explosion proof).
They can run dry.
The DIA-R pumps are highly recommended to stop using them as metering, because you can very easily regulate the flow through a valve at the air inlet. Instead of operating the engine are very suitable to raise paints, emptying drums, solvents, dyes, scents and liquid with small particles in suspension.
Also for corrosive chemicals, ceramics, porcelains liquid, liquid food products, oil, caustic soda, lye, hydrochloric acid, etc.
