This 3D animation was created to showcase the Yamada ½” Global Series G15 Aluminum Air Operated Double Diaphragm Pump. This exploded view demonstrates the breakdown and reassembly of the external and internal parts of the diaphragm pump.

I recently began working with a ceramic tile manufacturer in my territory that uses a good number of air operated diaphragm pumps that hadn’t been performing well.

Buyer beware! When you buy a Yamada Air Operated Double Diaphragm Pump from your local authorized distributor, you are not only getting the longest lasting diaphragm pump on the market, but you are getting the service you need to keep your machines operating for years to come.

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.

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.

In August of 2008 the NDP-20 / NDP-25 series pumps came with a new style diaphragm which has an o-ring molded into the air side. This change was made for two reasons: To prevent air leaks where the diaphragm contacts the air chamber. To prevent a diaphragm from pulling out of place if there is excessive air pressure.

Have you ever wanted to switch out your old pump for a Yamada, but faced re-piping issues?
