4 Function description
The 'EcoPro' diaphragm metering pump is driven by an electric motor and is intended for
conveying clean, non-abrasive dosage media.
The step motor technology used means that both the suction stroke duration and the
metering stroke duration can be varied.
This results in a variety of benefits such as a large setting range, virtually continuous and
low-pulsation metering, and even the option to respond to high viscosity or challenging
intake conditions.
The pumps consist of three main assemblies:
n Housing with driver unit
n Pump head
n Control unit.
The selected construction makes it very easy to change between the control units for the
'EcoPro' and 'EcoAdd' '' .
In addition, the control units can be rotated variably on the housing
unit' on page 78 .
Using the supplied mounting plate, the pump can be fastened to a tabletop or wall without
using tools.See also

.
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 delivery rate can be regulated by a trimming
potentiometer. A reduction in quantity means an extension in
the metering stroke duration. The duration of the suction stroke
remains unchanged (see also
rate' on page 50 ).
A low-noise stepper motor moves a metering diaphragm via an
eccentric gearbox (in type 00510X) or via an eccentric piston
rod (in all other types).
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.
