Special Application

•Horizontal , radially split volute casing type , single stage, end suction centrifugal pump with closed impeller.

•Dimensionally complies with EN 733.

•In addition to 24 basic sizes conforming with EN 733, there are 8 additional sizes. Dimensions of additional sizes may di�er from other suppliers.

•ECO SNT 40-315, 50-315, 65-315, 80-315, 100-315, 125-250 pumps are given with 2900 rpm only for fire fighting application.

•Suction and discharge flanges conform to EN 1092-2 / PN 16. For steel or stainless steel casing is EN 1092-1 / PN 16. In case of request, ANSI/ASME flanges can be supplied.

•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 or statically according to ISO 1940 grade 6.3.

•Axial thrust is balanced by impeller balancing holes system.

•Direction of rotation is clockwise viewed from drive end.

•In case of request, wear ring and/or shaft sleeve can be supplied.

•Bearings of ECO SNT type pumps are normally “life time grease lubricated” ball bearings. If there is a demand, oil lubrication or re-greasable bearing can be supplied.

•For ECO SNT drawings, please look at below adress www.standartpompa.com.

•In standard production, soft packed stuffing boxes are used.

•Depending on customer request, mechanical seals are available. In this case, pump shaft is always stainless steel.
