applications.
Suction and discharge flanges conform to EN 1092-2/PN 16.
(EN 1092-1/PN16 for steel or stainless steel casing).
If requested, ANSI/ASME flanges can be supplied.
The complete bearing assembly including impeller and casing cover can be dismantled without removing the volute casing from the piping system.
(Take out the rotor group without dismantling the electric motor, with spacer coupling application).
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.
If requested, a wear ring and/or shaft sleeve can be supplied.
Bearings of S-ENP pumps are normally “lifetime grease-lubricated” ball bearings. If requested, oil lubrication or re-greasable bearing can be supplied.

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.
