DescriptionThe FPUDT1500 Series injector pumps feature a heavy-duty cartridge valve pumphead made of injection-molded polypropylene. The pump includes double-sealed PVDF cartridge valve fittings, FKM O-ring seals, ceramic ball checks, Hastelloy C valve springs, and a PTFE/EPDM diaphragm. Units with the optional built-in electronic percentage 5 second cylce timer allow the user to adjust the feed rate with just the timer or to adjust both the stroke of the diaphragm and the timer for precise feed control. The pump can also be purchased as part of a tank system. See FPUTS1500.
