Pump head SP Vario
Pump heads of the type SP vario can be adjusted to different tube wall thicknesses. To
mount tubes on the SP vario pump head, proceed as follows:
➜ Remove the protector from the pump
head.
➜
Remove the clamping lever.
➜ Turn the Vario wheel to the [max.]
position using the adjustment aid
supplied (maximum opening for
maximum tube wall thickness).
➜
Insert the tube into the pump head.
➜
Turn the pump head rotor in such a
way that the inserted tube is prefixed
between the rotor and the housing
(see illustration, several turns may be
necessary!).
➜ Turn the Vario wheel with the
adjustment aid in the direction of the
[min.] position until there is clear
resistance.
➜
Remove the adjustment aid and store
it safely.
➜ Mount the clamping lever.
➜
Slightly tighten the inserted tube: Pull
on both ends with moderate force.
– Pre-tensioning increases the
service life of the tube and ensures
maximum operational reliability.
➜ Mount the protector.
➜
Perform a short test run before
commissioning to ensure continuity of
the mounted tube.
Small tubes
To stabilize small tubes (internal diameter
0.8 to 1.7 mm) in the pump head, use the
two supplied tube pieces (see scope of
delivery, section „Pump heads SP standard
and SP vario" auf Seite 77):
➜ Slide the tube pieces over the inserted
tube.
➜ Place the tube pieces in the two tube
guides and pre-tension the tube as
described.
➜
Mount the protector and perform a
short test run to ensure continuity of
the tube.
