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. Don’t be lured by online retailers offering pumps and parts at a discount. The merchandise that you receive may not be the quality products you come to expect from your “Yamada Guy”.

For example, a long time Yamada customer purchased the following balls for their 2″ pumps from an overseas online store. After just a few days of service, the results obviously weren’t very pretty.

it started with a fitting

By: Paul Rainer, VP Sales & Marketing of Yamada America, Inc.

In 1905, the late Jujiro Yamada established a factory in Minato-ku, Tokyo and began the manufacturing of valves and fittings. His son, Shotaro Yamada, took over from his father in 1923 and began to make hand operated grease guns. During his 49 year career, the company incorporated as Tokyo Yamada Yuki Seisakusyo and later changed its name to Yamada Yuki Seizo. It wasn’t until 1990 before it became the name it is today, Yamada Corporation.

Mr. Shotaro Yamada

Ultimately, hand operated grease guns evolved into pneumatically operated grease pumps and automotive equipment. Further development in pneumatics lead to the design and manufacturing of air operated diaphragm pumps.

Yamada remains in the forefront on development of quality, long lasting pumps for the industrial marketplace with locations in the USA, Europe, China, and Thailand. To think, it all started with a fitting!
