- 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
- Various possibilities for individual customer applications, e.g. contact or analogue signal control, batch or timer dosing
