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, 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.

Air-Operated Diaphragm Pumps RFM 40

The air-operated diaphragm pumps RFM/RFML is almost completely diffusion resistant due to the thick-surface structure. Available are versions with flap valves, FDA-certified and conductive versions (RFML) for use in hazardous areas.

The FLUX air-operated diaphragm pump RFM/RFML 40 is self-priming and protected against dry running. The pump is distinguished for its versatility and can be used for pumping low to high-viscosity media with solid particles, abrasive media, highly flammable media or liquids with high gas content.

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. FLUX air-operated 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.
Other main features of FLUX air-operated diaphragm pumps are their high-cost efficiency and a very low noise level. Each pump can be easily dismantled for optimum cleaning. A comprehensive range of accessories such as pulsation dampers, pressure controllers with filter units, stroke counters, and fittings guarantee the safe use of the pumps.

FLUX air-operated diaphragm pumps are positive displacement pumps consisting of two pump housings and one control valve part. Diaphragms within the pump housings securely separate the liquid section (red) from the air section (blue). Both diaphragms are connected by a selector shaft which is located in the control valve part. Compressed air inflating alternately the air sections causes a movement of the diaphragms (1st and 2nd cycle). The subsequent transfer operation is controlled by a control valve which is easy to dismantle. Due to their solid construction, the pumps are designed for continuous operation and do not require any special
maintenance.
