Operating method of the pump:
The pumps consist of three main assemblies:
n Housing with driver unit
n Pump head
n Control unit.
The construction has been chosen so that it is very easy to change between the 'EcoPro'
and 'EcoAdd' '' control units.
In addition, the control units can be rotated variably on the housing
unit' on page 183 .
Using the supplied mounting plate, the pump can be fastened to a tabletop or wall without
using tools.

CAUTION!
The use of a suction pipe with an empty signal provision and dirt trap from our
accessory programme is highly recommended to protect the metering system.
The empty signal system causes the pump to cut off if the medium in the
container drops below a certain level.
The pump is available in a number of variants:
n The version that includes complete software control via an operator panel is known as
'EcoAdd' '' .
n An additional Bluetooth PCB (
enables the unit to be controlled and evaluated using the 'Ecolab EcoAPP'
smartphone app.
A low-noise stepper motor moves a metering diaphragm using an
eccentric gear.
During the suction stroke, the return movement of the diaphragm
generates negative pressure and the metering medium is drawn into the
pump head via the suction valve.
During the pressure stroke, the diaphragm is moved forward, creating
positive pressure, and the medium is pressed through the pressure valve
into the metering line.
The delivery rate can be regulated by making an entry on the display.
Reducing the metering rate here means increasing the metering stroke
duration. The duration of the suction stroke remains unchanged. By
selecting a different dosage mode, the suction stroke duration can also
be modified for higher viscosities or challenging suction conditions.
