Submersible Pump
WORKING PRINCIPLE
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 rotaing
blade channel via the suction strainer,where it moves radially from the
centre outwards,acquiring energy both in the form of pressure 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
Pumps
are suitable for lifting clear water not containing abrasive
substances.These pump 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 seal. The motor and the pump are easily removed,making
maintenance and repair more simple.
THESE PUMPS
ARE PARTICULARLY SUITABLE FOR DRAINING FLOODING IN CONFINED AREAS
(BASEMENTS,GARAGES,ETC.),EMPTYNG SWIMMING POOLS.TANKS AND
AQUARIUMS,WASTE HOUSEHOLD WATER DISPOSAL(DISHWASHERS,WASHING
MACHINES),SUPPLYING GAREDN FOUNTAINS SMALL-SCALE IRRIGATION FOR GARDENS
IN GENERAL FROM COLLECTION TANKS AND EMPTYING SUMP PITS.
PERFORMANCE
When designing performance levels for pumps,special attention was given to typical requirements for domestic usage.
1.performance curves specially designed for high delivery rates at the low installed power rating.
STRUCTURAL CHARACTERISTICS
1.DELIVERY
BODY made from fibre glass reinforced technopolymer,particularly to
mechanical stress,knocks and corrosion,fitted with 11/4" gas threaded
vertical delivery opening.
