SQ Flex Advantages

  • SQ Flex Pumps can run on both DC and AC input voltages without any modification at site.
  • SQ Flex Pumps have inbuilt dry run Protection.
  • SQF Motors have high efficient permanent magnet rotors and can operate over a wide input voltage i.e. 30-300 V DC and 90-240V AC.
  • Built in MPPT in the Moto.r
  • Built in over voltage and under voltage Protection – The Pump will cut off if the voltage falls outside the Permissible voltage range. The Motor will automatically cut in when the voltage is again within the permissible voltage range.
  • Built in overload Protection –The overload Protection Prevents burnout of Motor. In case the upper load limit is exceeded, the Motor will automatically compensate for this by reducing the speed. If the speed falls below 500 rpm, the motor will be cut out automatically.
  • Over temperature protection- The electronic unit has built in temperature sensor when the temperature rises above 850C, the motor will automatically cut out. When the temperature dropped to 750C, the motor automatically cut in again.
