I often receive phone calls from end users about diaphragm cycle life and the first few questions I ask are: What pump are they using? What chemicals are they using and at what temperature? Is it a suction lift application or a flooded suction? At what flow rate are they operating the pump? After discussing these questions I find that several customers are running the pump at full throttle…

Proximity Sensors can be provided on almost any Yamada pump. They are used to send a signal every time the pump completes a cycle. This signal can then be used to count cycles for preventative maintenance. It can also be used to monitor flow rate.

There seems to be some confusion regarding what center rod is used with the various diaphragms. Hopefully this article, and the chart below will add some clarity to this issue.

Lightweight, rugged and reliable, our KPL-24 offers maximum portability and dependability in heavy construction machinery and wind turbine applications. The KPL-24 fits onto a standard 5 gallon grease pail and provides a discharge pressure of 4061 psi max. It can be used stand-alone or as a centralized lubrication system.

In the early months of 2008 the aluminum air chamber for the NDP-20 and NDP-25 series pump was modified with a groove in order to accommodate the newly designed diaphragms from Yamada.
