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.

I receive many calls from end user’s telling me that their pump has failed from dry running . Upon further investigation I find out that their problem is with a competitor’s piston pump, not an air operated double diaphragm pump.


For these applications we have suggested using our DRD-100 Dry Run Detector and have been receiving great results. So remember, dry run can be controlled on our pumps or the competition.
