ALLDOS Inc. DDI 209

DDI 209 very reliable even for pumping rates as low as 0.005 l/h Instead of having to convert the required litre capacity per hour into the corresponding stroke frequency (strokes per minute) of the pump, all you now need to do with DDI is enter the litres per hour. You no longer need either knowledge of equations or a pocket calculator. The stroke adjustment button is thus consigned to history. The pump can, be adapted quickly and easily to the user’s own specific process requirements. The calibration process is also particularly straightforward. The integrated microelectronics calculate the correction factor that is needed and within a few moments the pump is ready for high-precision operation. Even inexperienced operators require only a few minutes to learn the most important steps. DDI 209 – compelling benefits: Very consistent, finely tuned and, consequently, virtually continuous dosing The gentle suction motion reduces gassing of the medium and, in conjunction with the consistently high suction volume, ensures that the processes involved remain highly reliable even when difficult substances are concerned. Slow-Mode particularly for viscous media with low vapour pressure: This is an operating function where the suction stroke can be decelerated specifically.
