Functional description
4.1
Mechanical functions
The metering pumps
ELADOS
®
EMP II E60
and
E60
PLUS
are diaphragm metering pumps
driven by an electrical motor only suitable for use in commercial ranges.
The metering pumps are suitable for use with clean, non-abrasive metering media with a
viscosity of up to 200 mPas (measuring manner: Brookfield).
They are powered by a synchronous motor which is jam-proof and runs at a continuous RPM.
An eccentric drive moves the diaphragm and thus drives the metering medium over the
pressure valve (see chapter
, Pos.
6
).
The diaphragm is repositioned by means of a retaining spring. In this way, the metering
medium is sucked through the suction valve (see chapter
, Pos.
1
) into the pump head
, Pos.
4
).
The discharge flow can be sleeplessly regulated during operation via the stroke setting
(see chapter
, Fig. 5.5, Pos.
1
). In this way, the resetting motion of the diaphragm is
limited.
WARNING
To protect the metering device, the use of a suction pipe with an empty reporting device
and dirt arrestor (available from our range of accessories) is highly recommended! The
empty reporting device switches off the pump if it falls below a certain level (in container).
4.2
Electronic functions
The pump is operated using four keys (see chapter
, Fig. 5.5, Pos.
2
,
3
,
4
and
5
and also
chapter
The operating indicator is shown on a graphical display (see chapter
, Fig. 5.5, Pos.
6
).
4.2.1
Operation modes
The pump may be used in three different operation modes:
INTERNAL
Manual metering function (factory setting)
EXTERNAL
pulse control
EXTERNAL
standard signal control (mA)
The Configuration menu item can also be used to set batch metering (a specific quantity is
metered on each start pulse).
