Yamada AD-50ST Pulsation Damper

Description:

The Yamada AD-50ST is a pulsation damper used in fluid handling systems to smooth pressure fluctuations and reduce vibration caused by reciprocating pumps. It is commonly installed in diaphragm pump systems, chemical transfer lines, and dosing equipment where consistent flow and reduced pulsation are required. Maintenance teams, OEMs, and integrators purchase this unit for system stability, protection of piping and instruments, and retrofit of pump systems experiencing pressure spikes.

Applications:

The Yamada AD-50ST pulsation damper is used in industrial fluid handling environments where pressure stabilization is critical. It is commonly deployed with air-operated double diaphragm (AODD) pumps in chemical processing, wastewater treatment, coating systems, and fluid transfer applications where it minimizes pressure surges, reduces noise, and extends system component life.
