GRUNDFOS DME/DMS DIGITAL DOSING

Digital Dosing represents innovation in its purest form! No more complicated calculations In the past, traditional dosing equipment forced you to resort to complicated calculations to find the right setting. The exact dosage required to ensure that your dosing system was economical and safe had to be found by trial and error. And you would have to do it all over again whenever you needed to make adjustments. That all changed when Grundfos brought you Digital Dosing. Now, you simply specify the dosage you want and let the pump do the rest – with perfect confidence that you will get what you...

- what you set is wh Fieldbus Grundfos dosing pumps can be equipped with a fieldbus communication module. This lets you benefit from many types of information sharing. For example, the Digital Dosing pump can supply performance data and status information to be used for quality control, preventive maintenance, and future reference. You can monitor and control pumps from your PC, and you will receive immediate on-screen warnings if something should go wrong in the system. Fewer models cover all needs Grundfos covers the vast majority of all dosing needs with just seven Digital Dosing models....

cutting line only Pressure Time The advantages of the variable speed motor used in Grundfos dosing pumps are immediately evident when you compare them with standard pumps. The gold curve shows the pressure conditions in a traditional solenoid pump. Here, pressure peaks can be as high as 2.5 times the counter-pressure. Grundfos dosing pumps give you far better control of the process. As shown by the blue curve, pressure in a Digital Dosing unit builds up to the level of the counter-pressure and is controlled throughout the suction and discharge phases. Variable speed for smooth dosing The...
