Flux Air Operated Diaphragm Pumps Type FDM
FLUX air-operated diaphragm pumps are genuine all rounders for the safe, reliable and careful (no shearing) transfer of high viscosity products, even with solids in suspension, as well as abrasive, high flammability or aereated liquids. Each pump model is available in different versions because of a great variety of possible material combinations of the wetted component parts.

Special features:
- self priming even from a dry start
- variable delivery rates by simply adjusting air pressure to the pump
- no need of by-pass control
- no leakage due to absence of a shaft seal
- pumps are submersible
- unbalanced air valve design eliminates stalling
- ideal for use in hazardous locations
- no overloading; pump will stop in case of closed outlet
- suitable for dry operation
