WORKING PRINCIPLE
TOP 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 centre outwards, aquiring energy both in the form of presure 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 insured by the fluid being pumped.

PUMP INSTALLATION AND APPLICATIONS
TOP pumps 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 particularly suitable for draining flooding in confinced areas (Basements, Garages, ETC.), emptying swimming pools, anks and aquariums, waste household water disposal (Dishwashers, Washing machines), supplying garden fountains, small scale irrigation for gardens in general from collection tanks and emptying sump pits.

PERFORMANCE
When designing performance levels for TOP pumps, special attention was given to typical requirements for domestic usage.
- Performance curves specially designed for high delivery rates at the low installed power rating.
Curve tolerance according o ISO 2548
