Product introduction  \n3-inch SQ, SQE submersible well pumps for 3-inchand larger wells  \nSQ, SQE pumps are suitable for both continuous and intermittent operation for a variety of applications:  \n• Domestic water supply  \n• light commercial  \n• irrigation  \n• tank applications.  \nFeatures and benefits  \nSQ, SQE pumps offer these features:  \n• Dry-run protection  \n• high efficiency pump and motor  \n• protection against up-thrust  \n• soft-start  \n• over-voltage and under-voltage protection  \n• over-temperature protection  \n• high starting torque.  \nAdditionally, SQE pumps offer these advantages:  \n• Constant pressure control  \n• variable speed  \n• electronic control and communication.  \nSQ, SQE innovative motor technology  \nSQ, SQE pumps feature an innovative motor design incorporating permanent-magnet technology. By combining permanent-magnet motors and a Grundfos micro-frequency converter, we are able to deliver unmatched performance and the ability to control and communicate with the pump in ways never before possible. A few of the features that result from this combined technology are Constant Pressure Control, Soft-Start, and Integrated Dry-Run Protection, but these are just a few of the features these pumps offer.  \nSQ pump models operate at a constant speed much like today’s conventional pumps. The difference is that SQ delivers the benefits of an electronically controlled permanent-magnet motor that cannot be achieved with a conventional induction motor.  \nSQ pumps are available for single-phase power; a simple 2-wire design makes installation easy.  \nSQE pumps are equipped with a Grundfos \"Smart Motor. \" Like the SQ models, SQ pumps have a high efficiency permanent-magnet motor—but we add the ability to communicate.  \nThe \"Smart Motor\" communicates via the CU301 status box through the power leads.  \nIt is not necessary to run any additional wires down the well. Communication with the pump provides Constant Pressure Control and the highly useful ability to change the pump performance while the pump is installed in the well. Like the SQ motor, this is also a 2-wire motor designed for single-phase operation.  \nDry-running protection  \nThe pumps are protected against dry running. A value of P cut-out ensures cut-out of the pump in case of lack of water in the borehole thus preventing a burnout of the motor.  \nP cut-out is factory-set both for the SQ and SQE, SQENE pump","cbCaiub6Cn1cvJM1","https://ap.wps.com/l/cbCaiub6Cn1cvJM1","pdf",10213449,64,"English","# Product introduction\n## Features and benefits\n## Dry-running protection\n## High pump efficiency\n## High motor efficiency\n## Wear resistance\n## Protection against upthrust\n## Excellent starting capabilities","[{\"question\":\"What applications are SQ and SQE submersible pumps suitable for?\",\"answer\":\"They are suitable for domestic water supply, light commercial use, irrigation, and tank applications, and they can operate continuously or intermittently depending on the application.\"},{\"question\":\"How does dry-run protection work for SQ and SQE pumps?\",\"answer\":\"A factory-set P cut-out value switches the pump off when there is lack of water in the borehole, preventing motor burnout.\"},{\"question\":\"What are the key advantages of SQE compared with SQ?\",\"answer\":\"SQE adds constant pressure control, variable speed, and electronic control/communication capabilities, enabling performance changes while installed in the well.\"}]","Product Guide - SQ Series - Product Introduction | PDF",1790031257,161]
