C.R.I. Ultima Pump controller is yet another product from the house of C.R.I. having more than 5 decades of immense experience in pumping solutions.ntelligent pump controllers are basically variable frequency drives that gives complete protection to the pump against overloading, under loading, unbalanced voltages, dry run, phase reversal, phase failures etc. It monitors the pressure & flow rate within the system and regulates the pump speed to maintain the pressure level as per preset values. Hence both protection & desired performance can be obtained using this device. It is designed to connect to the discharge pipe using a 5-Way connector & accessories like pressure transmitter, pressure gauge are required for installation. Few models are designed to mount directly on the motor.
