(*) The material of pumps differ according to the type ofpumped liquid , operating temperature and pressure.Contact our company for deta iled in formation.
In standard production soft packed stuffing boxesare used.
Depending on customer requirement mechanicalseals are available. In this case, pump shaft isalways stainless steel.
Bearings of SNT type pumps are normally “life timegrease lubricated” rolling bearings, except the pumpSNT 200-500 and SNT 250-500 which are always oillubricated.
Depending on customer requirement pumps withoil lubricated or regreaseable bearing are available.
Direction of rotation is clockwise viewed fromdriver end.
The suction and discharge flanges are conformingto EN 1092-2 / PN 16.
Due to the back-pull-out design the complete bearingassembly including impeller and casing cover can bedismantled without removing the volute casing from thepipe system.
All impellers are balanced statically and dynamicallyaccording to ISO 1940 class 6.3.
Axial thrust is balanced by wear ring / balancing holessystem.
Horizontal , radially split volute casing type , singlestage, end suction centrifugal pump with enclosedimpeller.
Dimensionally complies with EN 733.
In addition to 29 basic sizes conforming with EN 733,there are 20 additional sizes. Dimensions of additionalsizes may differ from other suppliers.
