Experimental evaluation of the hydraulic and energy performance of three electric water pumping equipments

Abstract

The present work consists of testing three pumping groups used for
the supply of drinking water, to the test bench, to demonstrate the
behavior of the pumps used after repair and maintenance by the
SONEDE of Megrine (Tunisia). The experimental device of the test
bench is use to measure pressure, flow, power consumption and
efficiency. The experimental study of the hydraulic and energetic
performance of these three equipment revealed that the repaired
pumps had characteristics equivalent to the characteristics
announced by the manufacturers, with a slight lag of about 5%,
essentially due to the lifetime of the Pump tested. Compared to
SONEDE, maintenance of the operating pressure caused a slight
decrease in flow; this was corrected by a longer operating time.
