1.1 Scope of delivery
IMPORTANT!
Please unpack the peristaltic pump and ordered accessories attached with great care, so
that small parts do not remain unnoticed in the packaging. Please compare the scope of
delivery immediately with the delivery note. The reason for any discrepancies has to be
ascertained.
. Proper use
The proper use of the peristaltic pump is with the supply and metering of chemicals under
low pressure.
The appropriate operational conditions in chapter 4 „Technical data“ have to be main-
tained.
3. Function
The peristaltic pump is a positive displacement pump. The rotor’s pressure rolls squeeze
the pump’s hose together and when they roll on the hose they push the medium in the
hose in the direction of the pressure connection.
This functional principle is distinguished by its:
• simple function
• good suitability to media involving gas
The pressure rolls are spring loaded and can avoid possible deposits in the pump hose. As
a result the service life of the pump is increased for media with solid parts.
The delivery rate of the peristaltic pump is controlled by an on/off switch on the power
supply.
