Yamada® AD Series Dampeners
for Yamada® NDP and XDP® Series Air-Powered Double Diaphragm Pumps

Yamada® AD Series Pulsation Dampeners greatly reduce pressure fluctuations in fluid flow when mounted as close to the pump as possible. Yamada® AD dampeners incorporate a completely automatic self-relieving air motor if an increase or decrease in discharge head occurs.

For fluids with high solids content, Yamada® AD dampeners incorporate a flow-through design which keeps solids in suspension, maintaining dampener effectiveness. Yamada® AD dampeners do not restrict fluid flow, or increase fluid pressure, but compensate the voids and pressure fluctuations created by an air-powered double diaphragm (AODD) pump.

Metering/Injection/Dosing
Equalizes discharge pressure spikes, increasing accuracy.

Filter Press/Inline Filters
Increases filter efficiency and life by providing a smooth flow.

Spraying/Filling
Smooth, consistent spray pattern eliminates inconsistent filling and splashing.

Transfer
Eliminates harmful water hammer, preventing pipe and valve damage.
