A Pulsation Dampener That Suppresses Pulsation and Prevents Pump Damage

A PTFE-specification pulsation dampener dedicated for F series. A pulsation dampener with a wetted part made of fluorine resin, which uses compressed air to suppress pulsation of liquid transported by the diaphragm pump.
Use at plants where pulsation is not acceptable, such as for protection of filters and one-shot spraying.

[Note]
1. Install the damper within 1 m of the pump discharge port. It will have no effect even if installed at the end of the piping.
2. An even greater effect can be achieved by attaching and adjusting a regulator separately from the pump, in front of the dampener air supply port.
3. The dampener may consume air due to the pulsation condition.
4. Similarly to the pump, the diaphragm needs periodic replacement of PM.
5. The dampener will not function without back pressure. At least around 0.1 MPa of back pressure is required.

The maximum supply air pressure of a type with resin-made pump body depends on the liquid temperature. The water discharge is provided as a rough approximation only. The discharge will differ depending on factors such as the liquid to be transferred and the piping conditions.
