1/2 Diaphragm Pumps Bolted
- 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".
