NOTE
IF-Module may only be plugged in when the pump is de-energised
(voltage-free).
The described pumps are single-stage low-pressure centrifugal
pumps in compact design with a coupled motor. The pumps can be
installed both directly as a pipe installation pump in a sufficiently
anchored pipe or placed on a foundation base.
The pump housing has an IN-LINE construction, i.e. the flanges on the
suction and pressure sides lie along a centre line. All pump housings
are provided with a pump base. Installation on a foundation base is
recommended.
The electronic module controls the speed of the pump to a setpoint
that can be adjusted within the control range.
Depending on the control mode, the differential pressure follows dif-
ferent criteria. In all control modes, however, the pump adapts itself
continuously to the changing power requirements of the system,
which is the case especially when thermostatic valves or mixers are
used.
The main advantages of the electronic control are the following:
