Wilden Accuflo Pumps New Jersey Pennsylvania Delaware
Since 1955 Wilden has been the market leader in air-operated double-diaphragm pumps. Wilden Accu-Flo Diaphragm pump and accessories are designed to be safe in a host of difficult fluid transfer applications ranging from circulation duty in cleanroom environments to municipal sludge pumping. Wilden Accuflo Pumps turn a double diaphragm positive displacement pump into a metering pump by regulating air flow by powering a solenoid valve to control the direction of the air flow going to the pump. The Accu-Flo Air Distribution System uses a two position, four-way solenoid valve to control the flow of air. If you would like to learn how the air distribution system uses the solenoid to control the air flow click on the link to see How It Works. Wilden pumps are intrinsically safe by design, offering a wide range of material and elastomer options. Neoprene and Buna are two of the elastomer options for general applications while Teflon and Wilflex are offered for transferring more volatile liquids.
