  • Easy input and display of the dosing rate in l/h or gal/h with perfect calibration for optimum operating convenience and unparalleled levels precision
  • Smooth, nearly continuous dosing ensures a high process quality and optimal mixing of liquids
  • For especially viscous liquids, there are 2 slow mode steps and special valve combinations
  • Hotkey for easy query of the dosed quantity allowing optimal control of the consumption of chemicals
  • Low energy costs thanks to the EC motor technology with maximum efficiency
  • Pump excess pressure control by digital input of the maximum backpressure allowed before the pump stops
  • High process reliability thanks to the double diaphragm system
  • Radical reduction in variants and spare parts: 1 motor, 1 gearing and 2 dosing head sizes fit the complete pump series
  • Adjustment range 1:800
