The full touch screen interface enables the user to quickly create configurations and recall them for ease of use. The TFT colour display presents all the pump operating parameters on an easy to view run screen.

The password feature prevents accidental configuration changes ensuring the program integrity is retained. The pumps are versatile and can be interconnected through the RS485 interface.
