AD-25 series

Prevent Pump Damage Due to Pulsation!
Pulsation reducer exclusively for NDP series equipped with diaphragm. Affix to the discharge side of the diaphragm pump to reduce pulsation caused by pump operation.

■ Main Applications
Prevention of piping vibration/Protection of filters/Liquid pumps for metering devices, metering pumps in combination with flow meters, and other applications

[Caution]

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.
