Description of operation

4.1

Mechanical functions

The ELADOS
frequency convertor for use in commercial application.
The pump is designed to meter clean, non-abrasive metering media.
An eccentric worm gear (Item 4) moves the diaphragm (Item 2) and conveys the metering
medium via the pressure valve (Item 1). The suction valve (Item 5) is closed. The diaphragm
is reset by a return spring (Item 3). As a result, the metering medium is sucked into the pump
head via the suction valve. The pressure valve is closed.
The suction and metering stroke can be set at different lengths through the combination of
the integrated frequency convertor and corresponding control electronics.
The duration of the metering stroke and thus the metering quantity can be set within a range
of 1-100, whereby the suction stroke duration remains unchanged.
4.1.1

Electronic functions

The pump is operated via four buttons (Fig. 5.2, pos. 3, 4,
The operating display is shown in graphics mode (Fig. 5.2, No. 2).
4.1.2

Operating modes

The pump can be used in three different operating modes:
INTERNAL
EXTERNAL
EXTERNAL
The Configuration menu item can also be used to set batch metering (a specific quantity is
metered on each start pulse).
4.1.3

Metering modes

By selecting different metering
modes, the pump's motor speed and
suction stroke speed can be flexibly
adapted to high product viscosities or
difficult suction conditions.

• Oval gear meter connection
• Oval gear meter evaluation
• Metering control using an oval gear meter, OGM
• Possibility for automatic calibration through the use of the oval gear meter, OGM

If an appropriate length of metering stroke
duration is selected, metering which is virtually
pulsation-free can be achieved.
In addition, the suction duration can be adapted
flexibly to high product viscosities or difficult
suction conditions through the selection of
different metering modes.
