Pumps for hazardous materials GUP 3-1,5 and GP 20/10Ex
Attach the lifting tackle so that the pump
for hazardous materials can be safely lifted
(Fig. 2).
Either fold out the carrier handles and carry
the pump by these handles
or
attach carrier belts or ropes to the eyelets
on the carrier frame and lift the pump with a
hook.
In order to avoid slipping of the
sling the rope (belt) must be
crossed over at the hook.

The priming properties of the peristaltic
pump are based on the vacuum backed
restoring forces of its hose. Due to its paten-
ted design a vacuum is permanently gene-
rated inside the hose on the suction side of
the pump. This vacuum always restores the
hose to its original size.
The abutment 2 (Fig. 3) is an elastomer part
and is installed in the pump section where
the hose is squeezed to maximum extend.
This "soft contact base" of the hose pro-
longs its lifetime considerably.
At the same time this abutment protects the
pump housing against damage caused by
solid particles in case of a hose breakage.
In case of wear the abutment can be easily
replaced.
