Often, we get a request for a Pulsation Dampener with ANSI Flanges, rather than the standard NPT port. Yamada only offers the ANSI Flange port option on the AD-25 and AD-40 series dampeners.

In addition to our standard product line, Yamada offers a variety of surface finishes for our stainless steel pumps. These finishes are primarily used for food, pharmaceutical and high purity applications.

Yamada makes an automatic pulsation dampener, known as the AD Series Dampener. The AD Series Dampener is self adjusting and runs off the same regulated air supply that powers the pump.

The installation of a Yamada high pressure pump is the same as a standard Yamada Air-Operated Double Diaphragm pump. The bottom port is the liquid suction; the top port is the liquid discharge, etc. The main difference is the pumps ability to generate twice as much discharge pressure as air pressure, a 2 to 1 ratio.

With the introduction of the XDP Series pumps we needed to use a proximity sensor other than the P1 and P2 sensors used on the rest of the Yamada product line, which sense the position of the C-Spool to count the cycles of the pump.
