WORKING PRINCIPLE
The QSA is a single open impeller centrifugal submersible drainage pump designed to function either partly or totally submerged. The impeller, mounted on the end of the drive shaft, consists of a back disk and blades. The fluid enters the rotating blade channel through the suction, where it moves radially from the center outwards, acquiring energy, and the fluid leaves the pump via the side delivery opening in the pump body. Correct motor cooling is ensured by the fluid being pumped.
PUMP INSTALLATION AND APPLICATIONS
QSB is designed to pump clear or slightly dirty water not containing abrasive substances.
IT IS RECOMMENDED FOR SMALL EMPTYING JOBS SUCH AS FLOODED BASEMENTS AND GARAGES, HOLIDAY HOMES, TUBS AND USED DOMESTIC WATER DISPOSAL.
A purposely built pit with minimum dimensions 350 ˇÁ 350 ˇÁ 350h mm is recommended for fixed installation, to provide total drainage and allow correct operation of the float switch. This system automatically starts the pump when the fluid reaches a preset level, stopping it once the fluid has been emptied. Installing a suitable non return valve on the delivery pipe prevents reverse flow when the pump stops.
PERFORMANCE
When designing performance level for the QSA pump, special attention was given to typical requirements for domestic usage. ¨CPerformance curve specially designed for high rates at the low installed power rating.
