Diaphragms are the two flexible seals between spaces that contain liquid and air which move back and forth, both drawing and expelling fluid through the pump. Being the separation wall between the medium being used and the pressure. Unlike a piston and rod seal, there is no drag leakage.

Thanks to PTFE's excellent chemical resistance, PTFE Diaphragms is widely used in different pumps as a reliable separator between different media or space with different pressures.

PTFE diaphragms are commonly used in metering devices or process systems within the pharmaceutical, food and beverage, industrial and paint industries.

PTFE Diaphragms with Advantages: 

• • Absolute chemical resistance
  • Good reverse bending strength
