NPSH-Conditions
As the internal circulation from discharge to suction, doesn’t rise temperature in the pumped liquid the handling of boiling liquids is possible without an increase of NPSH-required.Balanced thrust loads
The thrust loads of the closed impellers are totally balanced by back vanes. Minimum residual forces that act in suction flange direction, are beared by strong silicon carbide, spring mounted, thrust bearings.Outer ball bearings
The outer magnet shaft is fitted in generously dimensioned anti-friction bearings. The bearings are L10 rated for an average life in excess of 5 years. The oil bath is protected against atmosphere by a lip seal (labyrinth oil seal on request).The oil level is controlled by a constant level oiler and additionally by a bull’s eye sight glass.Rear containment shell protection
The clearances between the outer rotating magnets and the stationary shell and between the rotating magnet holder and bearing bracket prevent magnets from rubbing on the rear containment shell in case of ball bearing failure.Internal circulation, pressurized containment shell area
When the pump is operating the heat generated in the containment shell and inner magnet area by eddy currents, is dissipated by an internal flow circulation from the discharge directly behind the impeller.
The pressure is increased by the rear impeller back vanes circulation, and come back to discharge.

maintenance.
Closed impeller statically and dinamically balanced. The axial thrusts are balanced by back vanes, for the best axial balancing independently from suction pressure.
Rear shell is made of one single piece, no welding, ellipsoidal profi le that has been studied to withstand higher pressures than the traditional one. Hastelloy® C276 is standard isolation shell material – providing a safe and effi cient solution – system pressure max 16 bar. Hybrid rear casing technology available for energy saving confi guration. Titanium Alloy is an upgrade when higher pressure ratings and increased effi ciency are required.
Double rear shell on request.
High power synchronous magnetic coupling designed by
our Technical Office and with rare earth magnetic elements
mechanically locked.
The high performance magnets can operate at liquid temperatures
of up to 662 °F (+350 °C) without external cooling. Transmittable
horsepower exceeds 520 kW / 700 HP.
