    Can we adjust the speed of motor of water pump?
    Sorry I don’t understand that variable speed means variable flow. And what is the purpose of variable?
    Can we adjust speed of the motor and is it a 3 phase motor?
    Is there a drive or can we operate it with a drive?
    Can I call you and which phone number?

    ATO Responded
    Yes, variable speed means variable flow. But the adjustment speed of single-phase water pump is very limited. If you want to adjust the speed and flow of the pump, we recommend that you use a three-phase 220V, 60Hz pump, and then cooperate with our single-phase 220V input and three-phase 220V output VFD.
    Could you please tell us what the head and flow requirements of your pump are? What is the specific flow range required for regulation?
