Diaphragm pumps

Serfilco Air operated Double Diaphragm Self-priming pumps AODD. All models offer non-metallic solution contact and will handle any product that pours, from clear water to highly viscous, abrasive and chemically aggressive materials.Diaphram pump models available Polypropylene 'PP', Nylon 'N', TFE 'K' or SS filled Nylon & certain models are molded of non-pigmented, non-reinforces polymers, eliminating product contamination. Compressed air or any non-flammable compressed gas activates these pumps. The pumping stroke begins as air is delivered by the air distribution system, putting pressure on one diaphragm and then the opposite one. A common shaft links the two diaphragms. The diaphragm pump pumping stroke on one side is simultaneously the suction stroke on the opposing diaphragm, automatically drawing fluid in one side while discharging fluid from the other. All models can rum dry & flow rates can be controlled to produce from zero to maximum flow simply by increasing or decreasing air flow or pressure.
