What is Pneumatic Dead Head Stop & Automatic Restart Protection Device (PDHR) for?
This pneumatic protection system turns off your Tapflo Air Operated Diaphragm Pump if the discharge pressure rises to a predetermined set point, protecting the pump from working inefficiently.
By using this closed discharge valve protection system, the lifetime of the pump’s diaphragm can be elongated. Moreover, the consumption of the compressed air can be reduced. It also limits the discharge pressure of the pump, which means more safe and reliable operation. When the discharge is open, pump will start automatically.
