Applications
Water supply, irrigation and sprinkler
Water treatment
Air conditioning
Cooling plants
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 1940 class 6.3.
Axial thrust is balanced by wear ring / balancing holes
system.
Bearings
Bearings of SNT type pumps are normally “life time
grease lubricated” rolling bearings, except the pump
SNT 200-500 and SNT 250-500 which are always oil
lubricated.
Depending on customer requirement pumps with
oil lubricated or regreaseable bearing are available.
Food and beverage processing
Paper and cellulose industries
Chemical and petrochemical industries
Fire - fighting
Power plants
Design Features
Horizontal , radially split volute casing type , single
stage, end suction centrifugal pump with enclosed
impeller.
Dimensionally complies with EN 733.
In addition to 29 basic sizes conforming with EN 733,
there are 20 additional sizes. Dimensions of additional
sizes may differ from other suppliers.
Pump Designation
Pump type
Discharge nozzle (DN)
Nominal impeller diameter
Shaft seal
In standard production soft packed stuffing boxes
are used.
Depending on customer requirement mechanical
seals are available. In this case, pump shaft is
always stainless steel.
Rotation
Direction of rotation is clockwise viewed from
driver end.
