Technology: Compressed air operated double-diaphragm displacement pump
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.
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.

From China to the United Arab Emirates, strong partners rely on our expertise for crude oil exploration applications.More Details
Natural gas, oxygen, and nitrogen are odorless but potentially dangerous. This is why these gases are "odorized" with as strong a smelling substance as possible. For more than 40 years, LEWA has been developing systems for the odorization of gases such as natural gases, biogases, and liquefied gases. This process is enormously important, so the odorizing system has to operate precisely and reliably.More Details
Crude oil must be cleaned, separated, and converted (refined) until the final products suitable for sale are made (e.g., gas, diesel, heating oil, lubricants, propane, butane). LEWA supports you with pumps and metering systems, which are used in the refining process during chemical metering. Application with our products are distillation plants, coker, cracker, or visbreaker, for example. Ask our experts for more information!More Details
We have supplied durable pumps and metering systems for applications such as the hydrocracking process for over 50 years. Petrochemicals generate starting products for the manufacture of plastics, pharmaceuticals, colorants, detergents, and other products. Contact our experts and allow us to provide you with detailed information about metering and pumping solutions for the hydrocracking process!More Details
When critical, environmentally hazardous, toxic, or flammable fluids and suspensions need to be reliably conveyed or metered in high-pressure processes, there is no alternative to hermetically sealed metering pumps, process diaphragm pumps, and metering systems from LEWA. Hermetically sealed LEWA pumps with pressures up to 1200 bar are the first choice for the production of chemical intermediate and end products. Contact our experts and let us advise you about your individual chemical pump or system solution!More Details
