Yamada^® Proximity Sensors are inductive switches that are installed to a pump and used to send a signal each time the pump completes a cycle. The signal can be used to count cycles for preventative maintenance, as well as monitoring flow rate. When used for one of these purposes, the signal is usually sent to a basic digital counter that has no control capability.

The Yamada^® DM-2 Diaphragm Monitoring System (DMS) is designed to prevent damage to your pump due to pumping corrosive, aggressive, or otherwise harmful fluids. Powered by a standard AC line current, the DM-2 automatically disrupts air supply pressure to the pump and/or activates an indicator (whistle or alarm) the moment a diaphragm leak is detected.

During some extreme conditions, the air valve of an air operated diaphragm pump can experience spool centering, causing equalization of pressure behind each diaphragm. To solve this, Yamada engineered an SVT retrofit kit designed to pneumatically activate the air valve to instantly start the pump operation, therefore ensuring continued productivity.

The Yamada DRD-100 Dry Run Detector provides protection to your air operated diaphragm pump from excessive cycling once it senses an increase in air volume, due to the loss of prime or dry running, and will automatically deactivate the pump. This will not only save air consumption but also your diaphragms.

Yamada^® Air-Operated Diaphragm #sanitarypumps are ideal for use in #dairy, #beverage, #pharmaceutical and personal-care applications. The proof's in the pump^®!
