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

General dataSubmersible pumpsSQE-NEApplicationsSQE-NE pumps are suitable for the followingapplications• sampling• remedial pumping• withdrawal of contaminated water at– dumps– chemical depots– industrial sites– garages and filling stations• pumping in water treatment systems• pumping of industrial process water• water quality monitoring.SQE-NE pumps are built for both continuous andintermittent operation.Note: For other applications, please contact Grundfos.Pump and motorSQE-NE pumps offer the following features:• dry-running protection• high efficiency of pump and motor• wear resistance• protection against upthrust• soft starting• overvoltage and undervoltage protection• overload protection• overtemperature protection• variable speed• electronic control and communication.The submersible SQE-NE pump is fitted with a singlephaseGrundfos MSE 3-NE motor, which is available inthree sizes with a maximum power P 2 of 1.7 kW.The MSE 3-NE permanent magnet motors are based onstate-of-the-art technology, which is the main reasonfor their high efficiency. The integrated electronic unit ofthe motors comprises a frequency converter for softstarting.The SQE-NE pump features variable speed which isoffered through frequency control. Consequently thepump can be set to operate in any duty point in therange between the min. and max. pump performancecurves.The SQE-NE pump features communication with theGrundfos CU 300 control unit, which can be operatedwith the Grundfos R100 remote control.The SQE-NE pump can also operate without theCU 300.The CU 300 provides full control of the SQE-NE pump.In case of a pump fault, an alarm will be indicated on thefront of the CU 300.The R100 enables monitoring of the installation andchanging of the factory settings.Pump and motor rangeProduct Description MaterialSQE-NE pump 2 and 5 m 3 /hMSE 3-NE motorPipe connectionType keyPumped liquidsThe SQE-NE pump is suitable for use with slightlyaggressive liquids such as contaminated groundwaterand groundwater containing hydrogen carbonate.SQE-NE pumps can pump liquids with a sand contentof up to 50 g/m 3 . A higher content of sand will reducethe pump life.Operating rangeFlow: 0.3 to 7.5 m 3 /hHead: Max. 153 m.Single-phasemax. 1.7 kWStainless steelDIN 1.4401, AISI 316Stainless steelDIN 1.4401, AISI 316Pump typeThreaded connectionSQE 2-NE Rp 1 1/4SQE 5-NE Rp 1 1/2Example SQ E 2 -50 NEPump rangeE = Electronic control and communicationRated flow [in m 3 /h]Head at rated flow [in mm]Material code:N = Stainless steel DIN W.-Nr. 1.4401E = Environmental.The pump is suitable for pumping of polluted liquids14
