Vertical, radially split volute casing type, single stage, end suction centrifugal pump with enclosed impeller made for your process
Handled Liquids type pumps are suitable for clean or slightly contaminated liquids with low viscosity. Technical Data Suction Flange Discharge Flange Capacity Head Speed Operating Temperature Casing Pressure (Pmax) DN 50... DN 300 mm DN 32... DN 250 mm up to 1700 m³/h up to m up to 2900 rpm -10 C to +10 C * 10 bar (16 bar) * (Pmax : Suction Pressure + Shut off Head) (*) The material of pumps differ according to the type of pumped liquid, operating temperature and pressure. Contact our company for detailed information. The suction and discharge flanges are conforming to EN 1092-2 / PN 16. Due to the back-pull-out design the complete bearing assembly including impeller and casing cover can be dismantled without removing the volute casing from the pipe system. All impellers are balanced statically and dynamically according to ISO 0 class 6.3. Axial thrust is balanced by wear ring / balancing holes system. Design Features Vertical, radially split volute casing type, single stage, end suction centrifugal pump with enclosed impeller. Shaft Seal Depending on liquid and operating conditions mechanical seals can be used. Volute dimensions comply with EN733. Pump Designation 125-315 21
