All-Flo is committed to the pursuit of designing and manufacturing the highest quality product available to the industry. Every pump is performance engineered and quality built to provide trouble-free service under the toughest conditions.

Why All-Flo Double Diaphragm Pumps?

• 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 diaphragm 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. Fewer parts and less down time keep maintenance costs low.
• All pumps built with PTFE elastomers have back-up Santoprene diaphragms. Santoprene is a highly resistant EPDM and polypropylene compound.
• Conductive models available.
• FDA and USDA rated materials are available.Five year warranty against defects in material and workmanship. Parts ship within 24 hours after receipt of order. Next day shipments on pumps and parts are available for a minimal expediting charge.
• Modular design in both band clamp and bolted models means that breakdown or rebuild of the pumps can be accomplished in 20 minutes or less.
