Wilden - Standard Compressed Air Diaphragm Pump
As the inventor of the compressed air-operated double-diaphragm pump, Wilden Pump & Engineering Co. introduced the first pump of this design in 1955. No other manufacturer of compressed-air diaphragm pumps can draw from so many years of experience. Development of this technology has continued. Today, Wilden has a comprehensive product line. The right solution is always available for general applications as well as for customized requirements.

Pro-Flo™ technology
The Pro-Flo™ patented air control system has only three moving parts: The asymmetric control piston, the pilot valve and the piston rod/diaphragm unit.
The small surface of the control piston is continually supplied with compressed air, while the larger surface is ventilated or bled via the pilot valve.
An air control system with maximum reliability.
Pro Flo X
The Pro-Flo X air control system is a further development of the proven Pro-Flo and Pro Flo V controls.
With the new type of effectiveness management system (EMS), the Pro-Flo X offers a flexibility that was previously unknown with compressed air diaphragm pumps.
The patented EMS is simple and easy to operate. By turning the EMS adjustment wheel, the metered quantity and air consumption can be adjusted - to the maximum metered quantity or the highest efficiency to reduce production costs. Pro-Flo X delivers a higher energy efficiency and a flexibility comparable to the industry standard, at lower cost.
Accu-FloTM
The Accu-FloTM air control system uses a 2/4-way solenoid valve with a spring-loaded piston. The control of the stroke frequency is done externally via an electrical pulse. The Accu-FloTM pump moves similarly to a conventional compressed air diaphragm pump through alternating presence or absence of a signal.
