Peristaltic Pumps Series IP 100-800
Since the pump is a positive displacement
pump it must be assured that the discharge
piping has no shut-off elements, pipe tapers or
components that could cause clogging of the
piping.
An On/Off-switch with locking against switching
on (e.g. lockable switch, switch with detachable
switching lever) should be installed near the
pump.
This is a precaution to avoid accidents, e.g.
when inspecting the inside of the pump.
To avoid overloading of the pump we
recommend the installation of a motor
protection switch.
Electrical installations and
connections must only be made by
a qualified electrician.
In order to ease the necessary service work it is
recommended to install approx. 1 - 1,5 m,
3 - 4.5 ft, removable lines (hoses or pipes)
between pump ports and pipe system (Fig. 10).
This provides sufficient working space for
changing the pumping hose.
The pump cover must always be easily
accessible!
Peristaltic pumps are variable displacement
pumps, which produce a pulsating product flow.
In order to prevent these pressure shocks from
being transferred into the piping system, both
pressure and suction sides should be fitted with
expansion joints (Fig. 10). As an additional
measure to minimize pulsation, the pressure
pipe can be fitted with an active pulsation
damper. These must be adjusted to the
respective working range. For optimal results
refer to the installation instructions provided by
the respective manufacturers of expansion
joints and pulsation dampers.

The use of shut-off valves in the pressure line
requires the installation of an overflow valve with
return line (or by-pass or an over-pressure
switch), in order to avoid damage to the peristaltic
pump caused by operating errors (Fig. 11).
Should this not be possible, the pump must be
switched off before closing the valve.
Peristaltic pumps must never be
operated against closed shut-off
elements!
