Grundfos DDI digital diaphragm dosing pumpfrom 75 ml/h up to 150 l/h with real setting of the flow rate. The integrated high-performance microelectronics and the innovative speed-regulated drive technology produce a precise and continuous dosing guaranteeing consistent media mixing and process quality. The dosing rate is simply entered in liters per hour – and the pump takes care of the rest.
Digital Dosing
The use of stepper motor/EC drives optimizes control of the stroke speed and makes it extremely accurate. The duration of each pressure stroke varies according to the flow setting. The suction stroke time always remains constant but can be lengthened using the anti-cavitation function and thus adapted to the relevant needs. This way suction always takes place with the full stroke volume. This results in continuous dosing and lower pulsation in the dosing system – important factors in ensuring smooth pumping of outgassing media and in installations requiring longer suction lines.
Cost-effective dosing
DDI keeps energy costs at a record low, thanks to the advanced EC motor technology. Maximum efficiency is also ensured even by flows of 150 l/h
With a high accuracy of +/- 1.5 % repeatability throughout the adjustable range, DDI pumps reduce the consumption of chemicals by precisely dosing the required amount.
