Operating instructions Peristaltic Pump ISI Series
8.4 Adjusting the roller pressure
- The peristaltic pump is equipped with
shims, in order to adjust the precise
distance from the axis of rotation to
the roller for correct hose compression
(also dependent on speed and
operating pressure).
- In order to achieve optimal life of the
pump hose, the compression force
of the pump hose can be adjusted
by placing a number of shims under
the pressing rollers. The shims (2) are
fitted between the rotor (1) and the pressing roller (3).
The number of shims will vary for each counter pressure situation.

Hose compression
1 Hose without compression
2 Insufficient compression (back flowing
media in the cavity will destroy the hose
within a short period of time)
3 Optimum compression
4 Excessive compression (increased wear
and tear to the pump and the hose)
