Operating Principle and Applications of Air-Driven Diaphragm Pumps [Explanatory Material]

The diaphragm pump of the tap flow is suitable for harsh industrial applications.

Diaphragm pumps are operated using compressed air as the driving source. Two diaphragms are fixed to each other by a single diaphragm shaft, and by periodically supplying pressure to the air chamber behind the diaphragm through an air valve switching mechanism, each diaphragm repeats a push-pull motion. The simple, compact, and highly reliable structure of the Taphflow diaphragm pump adapts to various applications in the industrial sector that require durability. 【Features】 ○ Capable of dry operation ○ Wide flow adjustment range ○ Few components, robust, strong, and long-lasting design ○ Oil-free air mechanism, air-driven ○ No power supply required For more details, please contact us or download the catalog.
