CONTRUCTION
CHARACTERISTICS
•
Close-coupled, multiple impeller
submersible electric pump.
The liquid end is located
underneath the electric motor,
which is cooled by the pumped
liquid.
•
Impellers are radial centrifugal type,
made of technopolymer.
•
AISI 304 stainless steel diffusers.
•
Outer sleeve, motor casing, suction
screen and shaft extension are
made of AISI 304 stainless steel.
•
Dry motor .
The electric motor is protected by a
double seal system with an oil
chamber. The silicon carbide
mechanical seal, highly resistant to
abrasion and wear, together with the
second mechanical seal, lubricated
thanks to the special configuration of
the oil chambers, guarantee
long-lasting reliability.
