    3. GENERAL 3.1 Description of the Pump Alarko Optima is a brand new type of circulation pump which regulates its speed according to the system needs by the ECM (Electronic Commutated Motor) technology and the controller on it, as well as saves energy with its various types of operating mode choices.

  • Page 7: Applications (Intended Use)

    Pump adjustments should be made taking into account this situation. The effect of the water-glycol mixture on pump performance according to the mixture rate is shown in the Alarko Pump Selection Software. To prevent glycol dissolution, do not exceed the maximum allowable fluid temperature in Section 3.4 and minimize operating time at high temperatures.

  • Page 8: Operating Conditions

    3.4 Operating Conditions Alarko Optima pumps are developed for the circulation and pressurization of the water flowing in the heating and air conditioning systems located in the residential, commercial and industrial establishments. Input Voltage: Single Phase 230 Volts AC (± 10%) and 50 Hz (earth protected).
