Air-operated diaphragm pumps

Air-operated diaphragm pumps

Self-priming pumps also for pumping abrasive media

FLUX air-operated diaphragm pumps are self-priming and protected against dry running. The pumps are distinguished for their versatility and can be used for virtually all types of media. Available in heavy duty (RFM) or injection-moulded/cast (FDM) version for a huge diversity of applications they are designed for high pressures of up to 8 bars and in addition to other properties they are outstanding for their ease of handling.

The 100 % start-up guarantee in every shut-down position guarantees reliability and safe operation. The flow is infinitely variable via the air pressure. In addition the flow rate is easy to calculate. As a result of the integrated silencer the compressed air-operated diaphragm pumps are low noise. In addition the pumps are low-maintenance, in particular if used for pure media.

How is a Air-operated diaphragm pump constructed?

FLUX Air-operated diaphragm pumps are 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 especially 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.

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