Shaft seal arrangementsCustom-built pumpsCool-Top® (high temperatures)Temperatures above 248°F normally result in a substantialreduction of seal life due to poor lubrication of theseal faces. As the temperature in the seal chamber doesnot exceed 248°F during operation, a standard Grundfosshaft seal can be used.The Grundfos air-cooled top does not require anyexternal cooling. An automatic air vent is required tovent the pump seal chamber.Air-cooled top with bearing flangeFor applications involving pumping of water up to 356°F,the pump requires a net positive inlet pressure,according to the vapor pressure of water.To prevent the axial thrust generated by the inlet pressurefrom being transmitted to the motor shaft andbearings, a bearing flange can be fitted between pumpand motor.General informationThe unique Grundfos air-cooled top shaft seal solution isrecommended for applications involving high temperaturesfrom 248°F to 356°F.The Cool-Top pumps are equipped with FXM rubberparts.Reference applications• Boiler feeding• Temperature control, e.g. in molding processes• Circulation of transmission oils.Pump rangeThe Cool-Top is available for the following Grundfospumps:248-356°FPumpCR 1s CR 1 CR 3 CR 5 CR 10 CR 15 CR 20 CR 32 CR 45 CR 64 CR 90typeCR • • • •CRI • • • • • • •CRN • • • • • • • • • • •GR5228A bearing flange may be required if the application inletpressure exceeds the maximum inlet pressure of thepump.

MAGdriveCustom-built pumpsMagnetic-drive pump (MAGdrive)General informationThe zero-leakage, custom-built pump with magneticdrive (MAGdrive) is recommended for the pumping ofhazardous or aggressive liquids. Grundfos MAGdriveprotects the surrounding environment and the peopleworking in the vicinity of the pump.Reference applications• Chemical industry (aggressive or toxic liquids)• Petrochemical industry (volatile liquids)• Pharmaceutical industry.Pump rangeThe following Grundfos pumps are available withMAGdrive:PumpCR 1s CR 1 CR 3 CR 5 CR 10 CR 15 CR 20 CR 32 CR 45 CR 64 CR 90typeCRCRICRN • • • •Technical descriptionIn the Grundfos MAGdrive pump, the power from themotor is transmitted to the pump shaft by means ofmagnetic force instead of by a traditional coupling. Themagnetic field is generated by two magnets; the outermagnet is driven by the motor and the inner magnet isconnected to the pump. Due to the power loss, theMAGdrive is cooled by the pumped liquid.As all axial forces are absorbed in the MAGdrive, astandard motor with key hole must be used.Grundfos MAGdrive is based on a standard MAK 66magnetic Burgmann coupling.Sectional drawingPump shaft250265CanBearing258Axial bearing 259MagnetsTM02 1721 1901DimensionsStandard motor[Hp]Operating rangePump typeReference numbersMAGdrive motor[Hp]Additional height[in]1/2 3/4 3 1/81/2 1 4 3/41/2 1 1/2 4 3/43/4 1 1/2 4 3/43/4 2 7 1/31 1 1/2 2 7/81 2 5 1/21 1/2 1 1/2 2 7/81 1/2 2 5 1/21 1/2 3 5 1/22 2 2 7/82 3 2 7/83 3 2 7/83 4 54 4 2 3/44 5 1/2 4 3/45 1/2 5 1/2 2 3/45 1/2 7 1/2 47 1/2 7 1/2 27 1/2 10 210 10 2Viscosity range[cp]Max. pressure[psi]Temp. range[°F]CRN 1s, 1, 3 and 5 0.3 - 150 232/362 –22 to +356Pump typeReference numberCRN 1s-2 to CRN 1s-27 98 94 82CRN 1-2 to CRN 1-27 98 97 07CRN 3-2 to CRN 3-25 98 97 05CRN 5-2 to CRN 5-12 98 97 03CRN 5-13 to CRN 5-24 98 97 02The following rubber part solutions are available:• EPDM• FXM• FFKM• FKM.Note: When ordering a Grundfos MAGdrive, pleaseprovide the following:• liquid temperature [°F]• liquid viscosity [cp]• frequency [Hz]• voltage [V].Above information is required for the selection of thecorrect MAGdrive/motor combination.18

LiqTecCustom-built pumpsLiqTec TM dry-running sensorGeneral informationThe Grundfos LiqTec dry-running sensor stops the pumpimmediately if• there is no liquid in the pump (dry-running)• the liquid temperature exceeds 266°F ±9°F• the sensor, sensor cable, electronic unit or powersupply failsWhen connected to the PTC sensors in the motor, theLiqTec also protects the motor against overheating.The sensor is easily inserted through the pump headclose to the shaft seal.TM03 0110 4004Restarting after a pump cut-out can be done automaticallyor manually when liquid in the pump is againdetected by the sensor. Remote restarting is possible viaa digital input.The electronic control unit can also be connected to thepump thermistor measuring the motor temperature. Incase of overheating of the motor, the system cuts outthe pump.Installation exampleL1L2L3NSensorBrown/BlackBlueWhiteExternalrestartT+T+T+M3K1Reference applicationsAny application involving a risk of dry running.Pump rangeThe LiqTec is available for the following Grundfospumps:PumptypeCR 1s CR 1 CR 3 CR 5 CR 10 CR 15 CR 20 CR 32 CR 45 CR 64 CR 90CR • • • • • • • • • • •CRI • • • • • • •CRN • • • • • • • • • • •Technical descriptionThe LiqTec transmits a heat impulse through the sensor,measuring the temperature of the sensor. Liquid in thepump cools the sensor as well as the shaft seal and otherpump parts.If there is no liquid present, the LiqTec detects a hightemperature in the sensor and cuts out the pump immediately.The risk of pump breakdown is thus furtherreduced by up to 50%.The LiqTec also prevents excessive liquid temperaturesfrom damaging the pump. If the LiqTec senses a liquidtemperature above 266°F, it cuts out the pump immediately.Further the LiqTec is a failsafe device, meaningthat the pump stops as soon as the sensor detects anerror on the sensor cable, the electronics or if the powersupply of the control unit is cut off.Dimensions4 5/8 x 3 9/16 in.
