Whats New?? Pumps with Electronic Interface

 

ARO Electronic Interface Pumps are air-operated diaphragm pumps with the most accurate, electronically controlled dosing available. With their best-in-class, smart design, ARO Electronic Interface Diaphragm pumps assure consistent flow rates and pinpoint control for a myriad of fluids and applications. Thanks to an internal solenoid valve, the pump offers uperior fluid control and repeatability, plus easy maintenance to keep operations running. Add reliable leak detection, an end-of-stroke sensor and cycle sensing, and you have an electronic interface pump with custom features you need right off the shelf.

ARO Controller Designed for Pump control Variety of Pre Programmed or user directed funtions allow plant manager to Customise the system to suit the Process Need  

Application

  • Ideal for Applications where pump has to be controlled remotely
  • Batching,Proportional Control and Dozing Applications;using a Local PLC. or  by Signals from your process PLC
  • pH control (Pump operates by 4-20mA output of your pH controller ;PLC control Optional)
  • Any other application where the Sensor gives an output ;pump will operate based on inputs from Sensor
