Operating instruccions Peristaltic Pumps
8.4.
Adjusting the roller pressure
- The peristaltic pump is equipped with shims, in order
to adjust the precise distance from the axis of rota-
tion 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 ro-
ller. 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.

1.
Hose in normal shape.
2.
Insufficient squeezing (back flowing media in the cavity will destroy the hose
within a short period of time).
3.
Perfect squeezing.
4.
Excessive squeezing (increased wear and tear to pump and hose).
