Sulzer submersible propeller pumps VUPX series

Sulzer submersible propeller pumps of the VUPX series are used where larger water volumes must be pumped up to relatively low heads (up to approx. 10 m). They are ideal for storm water pumping stations, for polder dewatering, for storm water protection, for irrigation and dewatering, for cooling and process water and for a multitude of other applications.

Construction

• The water-tight fully flood-proof motor and the pump section form a compact and robust unit.
• Water pressure sealed connection chamber, with two stage cable entry, protected against excessive cable tension and bending.

• Bimetallic thermal sensors in the stator which open at 140 °C.
• Rotor and rotor shaft dynamically balanced, upper and lower bearings lubricated-for-life, maintenance-free.
• Optimum motor cooling by directing the medium being pumped over the motor.
• Double shaft sealing.
• Lower sealing by means of a silicon carbide mechanical seal, independent of the direction of rotation.
• Upper mechanical seal in silicon carbide in case of motor size ME4 and in carbon/chrome steel in case of motor size ME5 and ME6, independant of direction of rotation.
• Separation chamber for ME4 and ME5 and oil chamber in case of ME6 with seal monitor sensor to indicate water leakage through mechanical seal.
• Hydraulic parts with axial propeller with 3 or 4 adjustable pro- peller blades or 3-blade propeller in the new Skew design and inlet diffuser on discharge side.
• These pumps are available both in standard and explosion-proof versions in accordance with international standards e.g. Ex d IIB T4/ATEX II 2Gk.

Motor
