Flux Air Operated Diaphragm Pumps and Mixers


The FLUX name has been synonymous with pump technology for more than 70 years. It was the invention of the electric drum pump that sparked it all off. In the meantime, of course, the technology has become more sophisticated. FLUX company innovations have markedly improved working routines for filling and transferring fluids. It is often said that medium-sized companies are the engines of progress.

FLUX is an invention. In the year 1950 the first electric drum pump was introduced. It was named FLUX. Out of this core the FLUX-GERÄTE GMBH was established. The medium-sized company based in Maulbronn develops and sells innovative solutions in the field of pump technology.

The air-operated diaphragm pump FDM is available in plastic and as metal version. The design ensures a completely oil-free operation. In addition, the pump is available as version for increased pressure (FDMH 25) and for the use in hazardous areas.

The mixer effect that flows develop depends on the shape of the container, the material and of course the type of mixer. Due to the flexible modular system FLUX is able to offer a wide range of options. This makes it possible to configure the mixer components of motor, shaft and mixing blade optimally for the application’s requirements. If low speed is required slow running versions can be configured which are provided with intermediate gear and special mixing blades. The FLUX mixers are available in various materials and with different mixing blades.

FLUX Air-operated diaphragm pumps are the most versatile and can be used for almost every liquid in all different fields of industry. Be it viscous products, even with solids in suspension, abrasive fluids, high flammability, or aerated liquids: FLUX Air-operated diaphragm pumps meet every application featuring high operation safety and reliability.

Due to their solid construction together with matched diaphragms, these self-priming pumps are specially designed for continuous operation. Diaphragm pumps ensure a very smooth liquid transfer (no shearing), are insensitive to solids in suspension, safe in dry running as well as totally overload-proof.
