1/2 Diaphragm Pumps Bolted

Diaphragm pump molded in polypropylene, conductive nylon, Kynar, Alum or 316Stainless. The Air Operated Double Diaphragm (AODD) pump is the most economical choice for all non-aggressive chemicals, water-based liquids and slurries. Water-based inks, paints, adhesives, DEF Urea and ceramic slurries are some common applications. Polypropylene offers excellent abrasion resistance and zero water absorption.
  • Patented, lube-free air valve system means no oil contamination of product and hassle free operation.
  • ALL-FLO’s patented air valve won’t stall at slow speeds
  • The air side of the pump is constructed of non-metallic materials. If a diaphragn ruptures or if fluid is spilled on the pump, these vital parts are not destroyed. Non-metallic air valve components are also much less prone to air valve icing when air lines contain water.
  • No air leakage when fluid discharge valves are closed.
  • All pumps are 100% tested prior to shipment.
  • ALL-FLO pumps are designed with service in mind.
  • ATEX Certified
  • Fewer parts and less down time keep maintenance costs low.
  • Five year warranty against defects in material and workmanship.
  • The Geolast used in the NC and SL models is a nitrile and polypropylene blend. When checking for chemical resistance on Geolast, use the resistance recommendation for nitrile (trade name Buna-N). Santoprene is an EPDM and polypropylene blend. When checking for chemical resistance on Santoprene, use the recommendation for EPDM. Pumps with Santoprene are designated with the suffix "E".
