Air-Operated Diaphragm Pumps

The ALL-FLO pneumatic pumps are at the forefront in materials and construction technology: in addition to the traditional materials (Polypropylene, PVDF, Conductive Nylon, Aluminum and 316 Stainless Steel), these pumps are available made in virgin PTFE (Teflon) in order to pump high purity liquids, while the stainless steel pumps are also available in the “All Pure” version, with FDA materials in contact with the pumped liquid. The pumps with wide passage “max pass” valves, allow to treat much more dirty and loaded liquids compared to the pumps equipped with the traditional ball valves, while the construction materials of the compressed air distributor eliminates the problem of stall at low working pressures and the icing of the compressed air.

Ideal pump for transferring clean fluids. The choice of materials of the pump body and membranes allows a wide chemical compatibility with the pumped fluids. Available in plastic materials (PP, PVDF, solid PTFE and Conductive Nylon).

Ideal pump for transferring clean fluids (with ball valves) and fluids also containing impurities (with max pass valves). The choice of the materials of the pump body and the membranes allows a wide chemical compatibility with the pumped fluids. Available in plastic materials (PP, PVDF, solid PTFE and Conductive Nylon).

Ideal pump for transferring clean fluids (with ball valves) and also fluids containing impurities (with MAX PASS valves). The choice of the materials of the pump body and the membranes allows a wide chemical compatibility with the pumped fluids. The plastic air valve ensures stall-free operation at low pressures and the absence of icing of the exhaust air. Available in metallic materials (aluminum and stainless steel AISI 316) and plastics (PP, PVDF, PTFE and Conductive Nylon).
