The Pumpac pump is activated by compressed air or any non-flammable compressed gas. The pumping stroke begins as the air is delivered by the air distribution system, putting pressure on one diaphragm and then the opposite diaphragm. The two diaphragms are linked together by a common shaft. The pumping stroke on one side is simultaneously the suction stroke on the opposing diaphragm alternately drawing fluid in one side while discharging fluid from the other side.
Discharge pressures relate directly to air inlet pressure and desired flow rate.
Non-Stalling Air Valve Pumpac's air distribution valve provides continuous operation at all speeds. Even extremely slow speeds and intermittent operation will not cause stalling. New, patented design remains lube free eliminating the need for an air-line lubricator. The lube-free design also means no contamination of product if there is a diaphragm rupture. Wide Ranges of Uses Pumpac's pumps handle any product that can pour, from clear water and thin volatile fluids to highly viscous, abrasive and chemically aggressive materials.
