What is Pneumatic Dry Run Protection Device (PDRN) for?
The pneumatic dry run protection device system turns off your Tapflo Air Operated Diaphragm Pump if the discharge pressure rises to a pre-determined set point, protecting the pump from working inefficiently.
To prevent damage to the bearings and shaft seal if the pumps run dry, It is always recommended to install dry-running protection on all Tapflo Air Operated Diaphragm Pumps.
By using this dry run protection system, the lifetime of the pump’s diaphragm can be extended. Moreover, the consumption of the compressed air can be reduced. After the pump has been turned off, it will need to be restarted manually.
