DDI Series

Grundfos Dosing DDI series is well established on the dosing pump market with its combination of innovative drive technology and integrated microelectronics. Users appreciate how they can simply enter the required dosing rate in liters per hour and let the DDI handle the rest.

Compact design - DDI pumps are smaller and quieter than conventional pumps in their class, making them easy to install anywhere. Order your DDI with the control and display interface on the side or front as you wish.

Turndown ratio 1:800 - The DDI 222 AR has a turndown ratio ten times better than that of traditional equipment, allowing us to create a complete pump series with just one motor, one gearing system, and two pump head sizes. You get the precision you want every time - and need only a minimum of spare parts and storage capacity.

Full stroke length every time - The DDI series use a full stroke length every time - a feature unique to Grundfos dosing pumps. Each stroke is carefully timed to bring you even concentrations in the system and optimal priming throughout the entire operating range.
