WORKING PRINCIPLE
POP pumps are open impeller centrifugal submersible drainage
pumps,designed for automatic use.The impeller,mounted on the
end of the drive shaft,consists of a back disk and blades.The
fluid enters the rotating blade channel via the suction
strainer,where it moves radially from the center
outwards,acquiring energy both in the from of disk and
increased speed.when it leaves the impeller the fluid is
conveyed into the volute.Here part of the kinetic energy is
transformed into pressure energy, and the fluid leaves the
pump via the vertical delivery opening in the pump body
.Correct motor cooling is ensured by the fluid being pumped.
PUMP INSTALLATION AND
APPLICATIONS
POP pump are
suitable for lifting clear water not containing abrasive
substances.These pumps have been designed for easy use and are
extremely reliable even when subjected to continuous use (e.g
in fountains),since the motor is fully cooled and has an ample
reserve of power plus a double mechanical seal.The motor and
the pump are easily removed,making maintenance and repair more
simple.
These pumps are particuarly suitable for draining
flooding in confined areas (basements, garages, etc.),
emptying swimming pools, tanks and aquariums, waste household
water disposal(dishwashers, washing machines),supplying garden
fountains, small-scale irrrigation for gardens in general from
collection tanks and emptying sump pits.
PERFORMANCE
When designing performance
levels for POP pumps, special attention was given to typical
requirements for domestic usage.
¡ù performance curves
specially designed for high delivery rates at the low
installed power rating.
STRUCTURAL CHARACTERISTICS
¡ù delivery body made from fiberglass reinforced
technopolymer, particularly resistant to mechanical
stress,knocks and corrosion,
¡ù suction
strainer made from fiberglass reinforced
technopolymer, providing the support base for the pump.
¡ù
Technopolymer hose joint with screw
fitting.
¡ù general electric Noryl gfn2v technoplymer open impeller.
¡ù external float
switch for automatic pump operation.
¡ù stainless steel motor shaft.
¡ù double mechanical seal carbon/alumina on the
pump side and sealing ring on the motor side(with barrier oil
chamber to lubricate and cool
the sealing surfaces in the
absence of water).
¡ù sealed induction motor,suitable for continuous duty with
built-in thermal cutout relay(motor protector).Insulation
Class F(provides the
motor with a considerable overload
tolerance and substantially increases the service life of
motor itself).Cooling of motor assured by the
liquid in
which the pump is immersed.
