DGFLOW PRESFLO V00101101 User Manual

EN
PRESFLO
®
is a device
that starts and stops the
pump to which it is fitted,
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 flow rate
required is zero or less than
the “shut-off flow rate” (Qa).
PRESFLO
®
’s electronics
protect the pump against
unsuitable operating
conditions such as dry
running or repeated start-
ups due to leaks.

è un
apparecchio che avvia ed
arresta l’elettropompa su
cui è installato sostituendo
i tradizionali sistemi a
pressostato / autoclave.
La pompa viene avviata
quando, all’apertura di un
rubinetto, la pressione
dell’impianto scende sotto
la “ pressione di marcia “ (
Pm), e viene fermata
quando la portata richiesta
si azzera o scende al di sotto
della “ portata di arresto “
(Qa).
L’elettronica di PRESFLO
®
protegge la pompa da
condizioni di funzionamento
anomale come la marcia a
secco o gli avviamenti
ripetuti dovuti a perdite
nell’impianto.

La pompe démarre lorsque,
après ouverture d’un
robinet, la pression de
l’installation descend sous
la « pression d’exercice »
(Pm), et s’arrête lorsque le
débit requis est effacé ou

d’arrêt”(Qa).
L’électronique de PRESFLO
