The DDI AR series has an innovative drive technology. It combines a powerful stepper motor with integrated contact signal control to bring you smoother, more accurate dosing. The user interface gives you a full range of options for customising the dosing process.

The DDI range eliminates the need for extensive calculation work associated with other dosing equipment. You will not need to work out how many strokes per minute are necessary to give you the desired dosing rate – simply enter the figure you want in the user interface, and the DDI does the work for you.

It has an ingenious stepper motor that extends the discharge phase throughout the full period between suction phases. In other words, it automatically adjusts the dosing speed to provide the right amount of additive at all times.

The DDI range is designed to give you superior flexibility and accuracy with as few product variants as possible. That is why you can adjust dosing rates within a 1:100 scale without any loss of dosing accuracy: the DDI series can dose additive in quantities down to 0.025 l/h with perfect precision – and evidence of this precision can be provided at any time while the pump is running.

DDI pumps can be used worldwide within the range of 100-240 VAC, 50/60 Hz. and available materials include PVC, PVDF, polypropylene and stainless steel.
