Groz AODD/15/BPS/N Air Operated Double Diaphragm Pump, 1/2 inch, 55 LPM

The Groz AODD/15/BPS/N is a self-priming, air-operated double diaphragm pump with a 1/2 inch polypropylene casing and a Santoprene diaphragm, suited to abrasives, acids and caustics. It runs on an air inlet pressure of 29-100 PSI (2-7 bar) through a 1/4 inch air inlet, delivering up to 55 LPM through a 1/2 inch NPT(F) inlet and outlet, with a discharge volume of up to 190 ml per cycle. Dead-head capability keeps discharge pressure from exceeding air inlet pressure, and the design tolerates dry running and fluids with high solid content, making it suited to waste-oil transfer and similar workshop duties.
