Grundfos Alldos DDI-209 Digital Dosing Pump 2.5L/hr

These pumps appear to have had very little if any use.

"DDI 209 dosing pumps are very reliable even for pumping rates as low as 0.005 l/h. Simplicity is evident immediately. 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 users own specific process requirements. The calibration process is also particularly straight forward. The integrated microelectronics calculates 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.

1. Very consistent, finely tuned, and consequently, virtually continuous dosing.
2. 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.
3. Slow-Mode particularly for viscous media with low vapor pressure: This is an operating function where the suction stroke can be decelerated specifically.
4. User-friendly batch programming with timer function. Simply enter batch start, batch duration and dosing flow, the pump will regulate the necessary dosing speed.
5. Contact signal control: Input in ml per contact with ingeniously regulated continuous dosing.
6. Current signal control: 4–20 mA with display of the current dosing capacity.
7. Total service-hours counter and total dosing flow counter.
8. Code function for protection against non-authorized access.
9. The memory function saves non-processed contact signals so that the pump can process them later."

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.

		User-friendly batch programming with timer function. Simply enter batch start, batch duration and dosing flow, the pump will regulate the necessary dosing speed.
		Contact signal control : Input in ml per contact with ingeniously regulated continuous dosing.
		Current signal control: 0(4) – 20 mA with display of the current dosing capacity.
		Total service-hours counter and total dosing flow counter.
		Code function for protection against non-authorised access.
		Memory function : Saves non-processed contact signals so that the pump can process them later.
