Application The JET Self-priming Pump combine functions and advantages of centrifugal pump and self-priming pump, It is suitable for pumping clean water without impurities and non-corrosive liquid. The major advantages of this pump are high discharge head, high suction head, high efficiency, and the self-priming time is quite short. Therefore, it is widely applied for irrigating garden, farmland and supply water to high-rise buildings. In addition, the pump must be installed in enclosed place or keep it away from inclement weather. Performance High heads with respects to power requirements Flat operating and power absorption curves, giving moderate curve variations with respect to large variations in deliver demand High tolerance of the presence of entrained air in the fluid to be pumped Operating limits Max. suction:9m Max. medium temperature+40°C Max. ambient temperature+40°C Max. pressure: 6 bar Transport medium: PH 6-8.5 Material and working limits 100% copper wire Pump body: Cast iron Motor housing: Aluminum Impeller: PPO Front cover: Aluminum Mechanical seal: Ceramic &Graphite Shaft: 45#steel/stainless steel Insulation class: B Protection class: IP44
