Yamada's air-powered double diaphragm (AODD) pumps feature a unique, patented air-valve design that ensures stall-free operation throughout product life.
Yamada AD-10 to AD-50
(Pulsation dampener for AODD pumps)
The Yamada Pulsation Dampener, AD series are used to prevent pulsation intrinsic to double diaphragm pumps. The AD is installed in the discharge line and decreases the pulse action of the fluid caused by the reciprocating action of the pump. The AD will prevent vibration and protects pipes, filters, metering gauges and flow meters. Bolted construction and common component replaceable parts maximise uptime and increase profitability.
