Part of Verder’s Verderair VA series of double-diaphragm pumps, the VA 25 includes a stall-free modular air valve for low pulsation and a smooth changeover. In the standard execution, the diaphragms are overmolded. Features include a one-piece center section; a leak-free operation and even sealing pressure by bolted design; installation flexibility with up to eight ports; and longer diaphragm life, especially for abrasive applications that require PTFE. Many material options can be combined making the diaphragm pump a good fit for several applications including drum fluid transfer, unloading fluids, chemical evacuation, ceramic glaze supply, dewatering and sump evacuation, and repackaging of fluids from original container to smaller receptacles. –
