MP 1, SQE-NE, SPA-NE, SP-NE - SCL Water

Technical dataSubmersible pumpsSQE-NETechnical dataSQE-NE pumpMains supply to pump1 x 200-240 V – 10 %/+ 6 %, 50/60 Hz, PE.StartingSoft starting.Stopping Soft stopping when stopped via the CU 300.Run-up timeMaximum: 3 seconds.No limitation to the number of starts/stops per hour.Built into the pump.Protection against:Motor protectionDry runningOvervoltage and undervoltage; the motor cuts out below 150 V and above 280 VOverloadOvertemperatureSound pressure levelThe sound pressure level is lower than the limiting values stated in the EEC Machinery Directive.Radio noiseThe SQE-NE complies with the EMC Directive 89/336/EEC.Standards: EN 50081-1 and 50082-2.Reset functionSQE-NE pumps can be reset via the CU 300 (possibly with the R100).Power factor PF = 1.Operation via generatorEarth-leakage circuit breakerPipe connectionBorehole diameterCU 300 control unitIt is recommended that the generator output is equal to the motor input power P 1 [kW] plus 50 %; min. P 1 + 10 %,however.If the pump is connected to an electric installation where an earth-leakage circuit breaker (ELCB) is used as anadditional protection, this circuit breaker must trip out when earth fault currents with pulsating DC content occur.SQE 2-NE: Rp 1 1/4.SQE 5-NE: Rp 1 1/2.Minimum: 76 mm.Maximum: 150 m below static water table (15 bar).For horizontal installation, a flow sleeve is recommended.Installation depthInstallation depth below dynamic water level:Vertical installation with/without flow sleeve: 0.5 m.Horizontal installation with/without flow sleeve: 0.5 m.NPSH Maximum 8 m.StrainerHoles in the strainer: ∅2.3 mm.Liquid temperaturePumped liquids30 °C: Flow velocity past the motor, 0.0 m/s (free convection).40 °C: Flow velocity past the motor, min. 0.15 m/s.pH: 2 to 13.Sand content: Maximum 50 g/m 3 . A larger sand content will considerably reduce the life of service parts.Supply voltage1 x 200-240 V –10 %/+6 %, 50/60 Hz, PEPower consumption5 WCurrent consumptionMaximum 130 mAEnclosure class IP 55Ambient temperatureIn operation: –30 °C to +50 °CIn store: –30 °C to +60 °CRelative air humidity Maximum: 95 %Pump cableMaximum cable length between CU 300 and pump: 200 mBack-up fuseMaximum: 16 ARadio noiseMarkingSensor inputLoadThe CU 300 complies with the EMC Directive 89/336/EEC.Standards: EN 55 014 and 55014-2.CE0-20 mA4-20 mA0-10 VDC2-10 VDCMaximum: 100 mA38
