Motors
General informationThe Grundfos standard range of motors meets a widevariety of application demands. For special applicationsor operating conditions, Grundfos offers custom-builtmotors such as

• explosion-proof motors

• motors with anti-condensation heating unit

• low-noise motors

• motors with multi-plug connection

• efficiency class 1 motors

• motors with thermal protection.

Explosion-proof motorsGrundfos offers explosion-proof or dust-ignition-proofmotors. Grundfos can supply ATEX approved motors in 2G EExe IIT3 , 2G EExd IIB T4, EEx 2D T125° and EEx 3D T125° version.All Explosion-proof motors has angular contact bearingsand PTC.

VEM 2G EExe II T3 is only available up to 28 kW as EExemotors are derated.

Reference numbers

Motors with anti-condensation heating unitHigh humidity may cause condensation in the motor.Slow condensation occurs as a result of low temperatureat night; rapid condensation occurs as a result of shockcooling caused by direct sun followed by tropical rain.

Designed to IP 65, Grundfos motors are capable of oper-ating continuously in applications with up to 85%humidity and temperatures up to 25°C and short-time upto 95% humidity at temperatures up to 40°C.

In applications with constantly high humidity levels above85%, the drain holes in the drive-end flange should beopen. This changes the motor protection level to IP 44.

If IP 55 protection is required due to operation in dusty envi-ronments, it is recommended to fit an anti-condensationheating unit on the stator coil ends.

The heating unit keeps the motor temperature constantduring nights and prevents condensation.

Grundfos motor types available with anti-condensationheating unit:

1 x 220-250 V, 50 or 60 Hz

Reference numbers

Low-noise motorsGrundfos offers low-noise Siemens motors with a noiselevel 7-8 dB below that of standard motors.

Note: The 15 kW and 18.5 kW standard motors for the CRseries are low-noise types.

Reference numbers

Calculation example showing energy savings of a high-efficiency motor:

Esaving = Energy savings per year

P2 = Nominal power output (4.0 kW)

toperating = Operating time (2,500 h/year)

Pload = Percentage of full load (90%)

ηnew = Efficiency of new motor (0.89)

ηold = Efficiency of old motor (0.86)

Esaving = P2 x Pload x toperating x (1/ηold – 1/ηnew)

Example:

Esaving = 4.0 x 0.90 x 2,500 x (1/0.86 – 1/0.89) = 353 kWh/year.

Motors with thermal protectionGrundfos offers motors with built-in bimetallic thermalswitches or temperature-controlled PTC sensors (ther-mistors) incorporated in the motor windings.

Grundfos motors from 3 kW and up have PTC sensors(thermistors) as standard.

Thermal switches

Examples of trade names are Klixon® and Thermik.

The thermal switches must be connected to an externalcontrol circuit to protect the motor against slow over-heating. The thermal switches require no tripping unit.

Protection according to IEC 34-11: TP 111 (slow over-heating). As protection against seizure, the motor mustbe connected to a motor starter.

Thermal switches tolerate the following maximumloads:

Umax = 250 VACIn = 1.5 AImax = 5.0 A (locked-rotor and breaking current).

The figure below shows an example of a typical circuit ofa three-phase motor with built-in bimetallic thermalswitches.

Double seal (back-to-back)

General information

Double seals mounted "back-to-back" are recommendedfor use with toxic, aggressive or explosive liquids. Theback-to-back double seal protects the surrounding envi-ronment and the people working in the vicinity of thepump.

This type of seal is the optimum solution for handlingabrasive or sticky liquids which would either wear out,damage or block a mechanical shaft seal.


• Paint industry

• Distilling plants

• Petrochemical industry.

Pump range

The back-to-back type of seal is available for thefollowing Grundfos pumps:


The back-to-back double seal consists of two shaft sealsmounted in a back-to-back arrangement in a separateseal chamber.

The pressure in the seal chamber must be higher thanthe pump pressure. The pressure in the seal chamber canbe generated by

• a pressure intensifier when the operating pressure is above 16 bar (see page 13)

• a separate pump, e.g. a dosing pump, when the oper-ating pressure is less or equal to 16 bar (see page 13) or

• an existing, separate pressure source. Many applica-tions incorporate pressurized systems.

The back-to-back double seal arrangement with pressu-rized seal chamber prevents the pumped liquid fromleaking through the shaft seal to the environment.

Air-cooled top (high temperatures)

General information

The unique Grundfos air-cooled top shaft seal solution isrecommended for applications involving high tempera-tures from 120°C to 180°C.

The following air-cooled top solutions are available:

• 120-150°C - EPDM rubber parts

• 120-180°C - FXM rubber parts.


• Boiler feeding

• Temperature control, e.g. in moulding processes

• Circulation of transmission oils.

Pump range

The air-cooled top is available for the followingGrundfos pumps:

120-150°C and 120-180°C


The air-cooled top separates the seal chamber from thepump by an air-cooled chamber, generating an insu-lating effect similar to that of a thermos.

Via the narrow passage between the pump and the air-cooled top, a small quantity of the pumped liquid recir-culates by natural circulation.

Temperatures above 120°C normally result in a substan-tial reduction of seal life due to poor lubrication of theseal faces.

As the temperature in the seal chamber does not exceed120°C during operation, a standard Grundfos shaft sealcan be used.

The Grundfos air-cooled top does not require anyexternal cooling.

An automatic air vent is required to vent the pump sealchamber.

Air-cooled top with bearing flange

For applications involving pumping of water up to180°C, the pump requires a net positive inlet pressure,according to the vapour pressure of water.

To prevent the axial thrust generated by the inlet pres-sure from being transmitted to the motor shaft andbearings, a bearing flange is fitted between pump andmotor.

A bearing flange is incorporated in the followingGrundfos pump types:

The max. permissible operating pressure of pumps withair-cooled top for temperatures up to 180°C is 25 bar.

Custom-built pumpsMAGdrive

Magnetic-drive pump (MAGdrive)

General information

The zero-leakage, custom-built pump with magneticdrive (MAGdrive) is recommended for the pumping ofhazardous or aggressive liquids.

Grundfos MAGdrive protects the surrounding environ-ment and the people working in the vicinity of the pump.


• Chemical industry (aggressive or toxic liquids)

• Petrochemical industry (volatile liquids)

• Pharmaceutical industry.

Pump range

The following Grundfos pumps are available withMAGdrive:


In 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.

Custom-built pumpsLiqTec

LiqTec dry-running sensor

General information

The Grundfos LiqTec dry-running sensor stops the pumpimmediately if

• there is no liquid present in the pump,

• the liquid temperature exceeds 130±5°C.

• the sensor, sensor cable, electronic unit or power supply fails

When 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.


Any application involving a risk of dry running.

Pump range

The LiqTec is available for the following Grundfospumps:


The 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 imme-diately to prevent damage. The risk of pump breakdownis thus further reduced by up to 50%.

The LiqTec also prevents excessive liquid temperaturesfrom damaging the pump. If the LiqTec senses a liquidtemperature above 130°C, it cuts out the pump immedi-ately. 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.

Restarting after a pump cut-out can be done automati-cally or manually when liquid in the pump is againdetected by the sensor.

Remote restarting is possible via a 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.

For installation of the Grundfos LiqTec, see the installa-tion example in the right column.

Pumps with bearing flange

General information

A bearing flange is used in two situations:

• A standard motor with standard ball bearing configu-ration is required: The bearing flange absorbs the hydraulic load from the pump, ensuring an acceptable motor bearing life.

• The pump is required to run at a higher inlet pressure than the maximum pressure recommended:The bearing flange prevents movement of the angu-lar contact bearing in the motor.


High-pressure applications such as

• cleaning

• boiler-feed water treatment

• reverse osmosis.

Pump range

The following Grundfos pumps are available withbearing flange:

Also avaiable for CRT 2, 4, 8, 16.


A bearing flange is an additional flange with an oversizeball bearing to absorb axial forces in both directions. Thecoupling is part of the bearing flange fitted in order toobtain optimum alignment.

The bearing flange requires a standard motor withkeyway.

Note: For motor sizes above 11 kW, the bearing flange isequipped with grease nipples and must be lubricatedregularly. Please follow the instructions on the bearingflange.

Belt-driven pumps

General information

A belt-driven pump is designed to operate in places withlimited space or where no electrical power is available.


Diesel-engine-driven or steam-turbine-driven applica-tions such as:

• applications in remote/distant areas

• mobile applications

• fire protection.

Pump range

The following Grundfos pumps are available as belt-driven pumps:



An additional bearing has been added on top of anexisting bearing flange. The two bearings are mountedback-to-back. This bearing design makes it possible towithstand the extra radial forces caused by a pulley.

A pulley wheel is attached to the end of the shaft.

By means of pulley belts, the pump can be driven by amotor mounted next to it rather than on top of it.

The pump can be mounted horizontally or vertically byusing the extra support plates.

The pulley head is positioned on the motor stool wherethe motor would normally be fitted. Using the existingholes in the motor stool, the pulley head can be securedto the motor stool with bolts, washers and nuts. Thepulley wheel is then attached to the shaft using anappropriate bush and key.

For extended bearing life, the following pulley wheelsizes are recommended:
