Grundfos® DMI
SIMPLE AND COST-EFFICIENT DOSING
Variations on the synchronous motor theme
The Grundfos DMI range comprises several variants for general or specific dosing purposes. Dosing heads and valves are available in different materials to suit a wide range of general water treatment and industrial applications.
 Although it appears to be a solenoid pump, the DMI is actually MOTOR DRIVEN. Whichever model you choose, you get a sturdy, cost-efficient pump based on a well-proven synchronous motor design. The DMI range can handle feed rates from 0.08 to 4.8 GPH (0.3 to 18 l/h) and pressures up to 232 psi(16 bar).
Silent operation
Regardless of model, the DMI pump is among the quietest pumps of its type available on the market today. It keeps its noise emission down to just 45 dB(A).
Flexible installation
The Grundfos DMI is suitable for both horizontal and vertical installation. If installed horizontally, the control elements are located on the unit’s top for easy access. Pump head materials include: PVC, PP, PVDF, and 316 SS.
Gentle dosing — less maintenance
The synchronous motor technology used in the Grundfos DMI range combines accuracy and reliability. Unlike solenoid pumps, pulsation spikes are limited, reducing vibration, wear, and tear on pump and system components.
Manual or external control
The DMI is offered in two control versions: variant B for simple manual control, or variant A which will operate manually or from an external contact generated pulse.
