working principle
POP vortex pump is a
submersible vortex pump,for dirty water,designed mainly for
domestic use.
Their operating principle is that of a
centrifugal pump with a retracted vortex impeller.A large
sized ring chamber with a threaded delivery opening is
machined in the pump body and closed at the front by a
cover,housing the suction opening,which is shaped to prevent
suspended solid over a certain sized from entering the pump.
Since the impeller is retracted with respect to the cover
,water entering the front chamber lying between these two
components assumes a vortex motion and is centrifuged into the
ring chamber,leaving the pump via the delivery opening.This
principle does not require the pumped liquid to pass directly
through the impeller,enabling the pump to handle suspended
solids without risk of clogging.
pump
installation and applications
POP vortex pump is
suitable for lifting dirty water,not chemically aggressive to
the pump components.This pump has been designed for easy use
and it is extremely reliable even when subjected to continuous
use. Since the motor is fully cooled. It is particularly
suited for domestic use,to drain dirty water in all cases
where suspended solids up to 20 mm have to be dealt with.
Recommended applications therefore include emptying of pools
and tanks,disposal of domestic sewage,emptying of sump
pits.
