The JET series are SELF-PRIMING CENTRIFUGAL PUMPS. Self-priming is achieved using an ejector, housed in the pump body. The total delivery produced by the closed centrifugal impeller is sent only party to the delivery opening. The remaining water is recalculated through the ejector, which is connected to the suction chamber and generates the necessary vacuum of self-priming the pump. When first starting the pump is started up the water, without bothering to fill the section piping and eliminate any air pockets. When the pump is started up the water in the pump body circulates through the ejector and transfers any air from the suction to delivery chamber, expelling it through the delivery piping. At the same time the vacuum thus generated causes water to rise in suction piping, thus self-priming the pump. Since the self-priming system operates continuously, these pumps are practically unaffected even by the presence of large amounts of entrained air in the fluid being pumped. The JET series, based on past TOP experience, is designed with particular attention to hydraulic efficiency and choice of materials. The result is a compact, quiet high performance pump
PUMP INSTALLATION AND APPLICATIONS
These pumps are suitable for pumping clean water and fluid which are not chemically aggressive to pump components.
THEY ARE EXTREMELY RELIABLE, ECONOMICAL AND SIMPLE TO USE, BEING PARTICULARLY SUITABLE FOR DOMESTIC APPLICATIONS SUCH AS THE AUTOMATIC DISTRIBUTION OF WATER FROM SMALL AND MEDIUM-SIZE TANKS, WATERING GARDENS, ECT.
These pumps should be installed in a covered area, protected against the weather.
The wide range of pump in the JET series satisfied the most varied the most varied requirement with features such as:
- high heads with respect to power required;
- flat operating and power absorption curves, giving moderate curve variations with respect to large variations in delivery demand;
- high tolerance of the presence of entertained air the fluid to be pumped;
suction capacity up to 9 meters
