ELECTRONIC PUMP CONTROLLER
PRESFLO is a device that
®
starts and stops the pump to
which it is fi tted, thus replacing
traditional pressure switch /
surge tank systems.
The pump is started when, as
a tap is turned on, the pressure
within the system drops below
the "start-up pressure" (Pm),
and is stopped when the fl ow

Operating conditions
A. Compatible/non compa-
tible fl uids
PRESFLO is suitable for use
®
with clean water and chemical-
ly non-aggressive liquids. If the
fl uid contains impurities, a fi lter
should be fi tted upstream.
B. Environmental conditions
PRESFLO should not be used
®
where there is the risk of an
explosion. The temperature
of the location should range
between 0°C and 40°C, and
the humidity should not exceed
90%.
C. Power supply
Make sure that the variation
rate required is zero or less
than the "shut-off fl ow rate"
(Qa).
The electronics of PRESFLO
protects the pump against
abnormal running conditions
such as dry running, repeated
start-ups due to leaks in the
system or overcurrents.
