Description
High efficiency self-priming centrifugal pumps with built in
large capacity prefilter. Extremely quiet runningand
great reliability, developed for water circulation and
filtration in domestic and residential swimming pools.
Suitable also for special applications that call for
handling of aggressive liquids, in fish farms, agriculture
and industry. Pump body in fibreglass reinforced
technopolymer. Strainer cover in clear antioxidant
polycarbonate to guarantee constant visibility through
time. Nylon strainer. Impeller in fibreglass-reinforced
technopolymer developed to ensure total coverage and
isolation of the motor shaft from the pumped liquid.
Diffuser in reinforced technopolymer. Mechanical seal
in carbon / alumina / NBR / AISI 316. Pump body O-rings
in NBR, threaded fasteners and reinforcing rings in AISI
304. Butterfly drain plugs that can be removed and
refitted without tools.
Asynchronous continuous duty 2-pole motor (S1)
with generous range of power ratings from 0.5 HP
to 3 HP, single phase and three-phase (see technical
specifications). Motor casing in die cast aluminium with
electrophoresic surface treatment to prevent oxidation
even in aggressive environmental conditions. Baseplate
supplied as standard with rubber mounts to reduce
vibration transmission.
Single phase version with integral thermal and
overcurrent protection and permanent split capacitor
(PSC), assembled inside the terminal box for all versions. -
