  • Double diaphragm with leakage alarm device is available.

Motor Optional

  • Power supply: standard in 3 phase/50Hz/380, 4 poles motor.
  • 60Hz/440V or other voltage motor available.
  • Enclosure of protection, IP55, Insulation, class F, IEC standard.
  • Other motor options: explosion proof motor and variable frequency motor.

Flow Adjustment

By the manual micrometer.
By the variable frequency motor together with the inverter or other variable speed drive.


Double Diaphragm with Leakage Alarm Device

When for the toxic & explosive liquid, double diaphragm with diaphragm rupture detecting system is available.
It can always monitor the leakage; once the diaphragm ruptures, it can alarm in 0.2 to 6 second, and stop the pump immediately.
