Wilton Corporation of the United States developed the world's first pneumatic diaphragm pump. Through continuous process improvements and technological innovations over the past fifty years, Wilton's products holdaglobal market share of55%, making it the largest manufacturer of pneumatic diaphragm pumps and accessories. Wilton Pumps currently offers eight specifications (1/4inch--4inch inlet), with a flow rate of up to275GPM(1040L/Min), an output pressure of up to125Psig(8.6Bar),and a temperature of up to176.7℃ (350℉). Structural materials include: aluminum alloy, cast iron,316stainless steel, corrosion-resistant nickel-based alloy, polypropylene, polyvinylidene fluoride, carbon-filled acetal, and Teflon. Suitable for industries such as paint, mining, chemical, pulp and paper, wastewater treatment, electroplating and surface treatment, oil and gas, ceramics, semiconductors, food and pharmaceuticals, and marine. Due to the absence of tightly fitted components, particles can pass through the pump without damage. Abrasive and viscous materials can also be easily pumped without altering the liquid's properties. The pump can run dry and self-prime in many process and waste applications without risk. With no packing or mechanical seals, Wilton pumps are suitable for handling flammable liquids.
