Industries

Design Features:

Horizontal ring section, multistage, centrifugal pumps with closed impellers and diffusers in end suction design.
7 Models from DN 40 up to DN 150 discharge flange diameter.
Suction nozzle flanges conform to EN 1092 - 2/PN 16 and discharge nozzle flanges conform to EN 1092 - 2/PN 40 (PN 63) (For steel or stainless steel casing pumps, flanges conform to related pressure class ratings defined in EN 1092 - 1).
Discharge flange is on top for standard production, upon request different discharge flange positions can be applied.
All impellers are balanced dynamically or statically according to ISO 1940 class 6.3.
Axial thrust is balanced by impeller balancing holes system.
Direction of rotation is always counter clockwise viewed from drive end. That is why these pumps can not be accouppled directly with diesel engines.
Bearings of S-EMP type pumps are grease lubricated.
Journal bearing used in the suction side is lubricated by the pumping liquid.

Shaft Sealing

The standard shaft seal is a mechanical Carbon/Silicon carbide with EPDM.
Different seal variants are available depending on customer requests and liquid types.
