Operation manual

A. NOTIFICATIONS FOR DOSING PUMP :

  1. Pump protection devices such as dry-running protection devices, fuses, Y Strainer, over-pressure relief valves must be installed.
  2. Pressure gauge, flow meters for pump control
  3. Pump flow must be set according to flow direction
  4. Power supply to the pump must be stable (3 phase, 380v, 50Hz or 1 phase, 220v, 50Hz), ground must be connected to the motor, the cab must meet the standard, suitable capacity of motor
  5. Rotation of the pump motor, indicated on the pump body.
  6. Insert the inlet and outlet pipes according to the standard of the pump, clean the pipe before connecting to the pump
