At the foot of the ejector must be installed a foot valve or a check valve. Installed the pump, fill completely both pipes and pump body with clean water. To preserve an efficient priming it is necessary a certain pression in the circuit, therefore it is recommended to install a membrane tank at the delivery of the pump.OPERATING LIMITS-Total suction lift up to 9 mt. with foot valve -Max. operating pressure: 8 bar. -Max. ambient temperature: 40ºC -Lliquid temperature up to: 60ºC -Max. altitude: 1000 m.DESIGN FEATURES-Pump body:cast iron-Impeller: Brass -Ejector union:PPO -Internal thermal protector -Motor shaft: AISI1045 -Mechanical seal: NBR/Graphite/CeramicMOTOR-Single phase power supply with capacitor permanently activated-Insulation class: B -Protection: IP44 -Speed of rotation: 2850rpm -Continuous duty: S1SPECIAL FEATURES ON REQUEST-Stainless steel welding shaft. -PPO or SUS304 impeller -FPM/EPDM/SIC/WC mechanical seal -Other voltage and frequency-Three phase power. -Electrophoresis anti-rust treatment
