Product Specification Sheet Handled Liquids Clean or slightly contaminated low viscosity liquids without solid & fibrous particles. Technical Data Discharge Flange Operating Temperature Casing Pressure (Pmax) Design Type (Pmax: Suction Pressure + Shut off Head) (*) The Material of pumps differ according to the type of pumped liquid, operating temperature and pressure. Contact for detailed information. Design Features •Horizontal , radially split volute casing type , single stage, end suction centrifugal pump with closed impeller. •Suction and discharge flanges conform to EN 1092-2 / PN 16. (EN 1092-1 / PN 16 for steel or stainless steel casing) •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. (With spacer coupling application, also possible to take out the rotor group without dismantling the electric motor.) •All impellers are balanced dynamically according to ISO 1940 class 6.3. •Axial thrust is balanced by impeller balancing holes system. •Direction of rotation is clockwise viewed from drive end. •Bearings of SNT type pumps are normally “life time grease lubricated” ball bearings, except the pumps SNT 200-500 and SNT 250-500 which are always oil lubricated. Shaft Sealing •Dimensionally complies with EN 733. •In standard production soft packed stuffing boxes are used. •In addition to 29 basic sizes conforming with EN 733, there are 17 additional sizes. Dimensions of additional sizes may differ from other suppliers. •Depending on customer request, mechanical seals are available. In this case, pump shaft is always stainless steel.
