Digital Dosing
Digital Dosing represents state-of-the-art technology.
This patented Grundfos solution sets new standards,
including new principles and methods.
Fig. 2 DME pumps
Precise and easy setting
The operator can easily install and set the pump to
discharge exactly the quantity of dosing liquid required
in the application. In the display, the setting of the
pump is read out directly in ml/h or l/h, pulse or batch,
and the operation mode is easily identified by means
of icons.
Unique technology
A unique drive and microprocessor control ensure that
dosing liquids are discharged precisely and with low
pulsation even when the pump is operating with high
viscosity or degassing liquids. Instead of the
conventional stroke length adjustment, the capacity of
the DME is regulated by automatic adjustment of the
motor speed during the discharge stroke and by fixed
suction stroke speed, ensuring optimal and uniform
mixing.
Fewer variants to cover all needs
The pumps feature a powerful variable speed motor, a
turn-down ratio of 1:800 and a complete control
interface including:
• Full pulse control
• Pulse batch control
• Internal timer batch control
• Analog 0/4-20 mA control
• Level control
• Fieldbus communication module.
This ensures that the DME pumps cover the range
from 60 to 940 litres per hour up to 10 bar. The switch
mode power supply ensures that the same pump is
working precisely, irrespective of the mains supply
(100-240 V, 50/60 Hz).
The DME dosing pumps feature diaphragm dosing
head with integrated vent valve, suction and discharge
ball valves. The pumps are fitted with power cable and
plug.
