1/4 inch Diaphragm pumps

Double diaphragm pumps are operated by compressed air or any non-flammable compressed gas. The pumping stroke begins as 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 rod. 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

This pump is ideal for low flow applications involving the transfer of inks, machine tool coolant, DEF Urea and waste oil. Diaphragms in Nitrile, EPDM, and Viton. Next size is 1/2" to 17gpm.Drum Pumps for DEF Click here
