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.
