Dosistar Grainy 230V

For flow control of three-phase pumps

The DOSISTAR GRAINY 230V is intended for controlling pumps with 3-phase asynchronous motors of low to medium powers. It is connected stationary to the 230V power supply. The current throughput of the pump (l/h) is measured with an external flow meter and then adjusting the flow setpoint. Operating modes are continuous flow control and batch dosing.

Area of application

  • Flow control of liquids
  • Batch dosage with remote control function
  • Quantity logging
  • Feed preservation
  • Grain preservation
