vertical centrifugal immersion pumps - SONDERMANN Pumpen + ...

THE PERFECT PUMP-DRIVEThe advantages of the variable-speed drive integrated in the motor:• Energy saving• Fluid control to suit your requirements• Space-saving drive• No power loss in the switch cabinet by the FC• Less installation work• The pump is delivered ready to connectand pre-programmed• No long, cost-intensive, shieldedmotor cables• No separate EMC filter• Gentle pumping of the medium• No heating-up of the pumpedmedium by energy dissipation• No external motor circuit breakersthanks to integrated motor protection functionsINTERNATIONAL MAINS VOLTAGES AND FREQUENCIESWest Europa East Europa Middle East Far East North America Central America South America Africa50 Hz 50 Hz 50 Hz 50 Hz 50 Hz 50 Hz230/400 V 230/400 V 220/380 V 230/400 V 220/380 V 220/380 V500 V 690 V 230/400 V 220/380 V 127/220 V690 V 240/415 V 200/346 V 240/415 V240/415 V100/200V60 Hz 60 Hz 60 Hz 60 Hz220/380 V 120/240 V 115/200 V 220/380 V254/440 V 265 /460 V 220/380 V 277/480 V110/120 V 277/480 V 254/440 V 115/ 200 V575 V600 VInstallation instructionsIn order to guarantee safe operation of vertical centrifugalimmersion pumps, the following instructions must be followedduring the planning and installation phases:A Thread length, suction side (for screwing onan extension pipe)L Immersion depthVL Extension pipe, suction side (max. 500 mm)X Minimum distance between the suction connectorand the tank bottomY Lowest permissible liquid level during any pumpstart-up. If a tank is emptied, it must be refilled toabove the minimum liquid level before being startedup again. While the pump is in operation, the liquidlevel can be reduced until the screwed-on extensionpipe is still below the level, without the pumpingflow being interrupted.Z Highest permissible filling levelRT – Vertical centrifugalimmersion pumpRT – Vertical centrifugal immersionpump with screwed-on extensionpipe on the suction side8
