Examples of MTRE applications

An MTRE pump is the ideal solution in a number of applications characterized by a need for variable flow at constant pressure.

Depending on the nature of the application, the pump offers energy-savings, increased comfort or improved processing.

MTRE pumps in the service of industry

Industry uses a large number of pumps in many different applications. Demands on pumps in terms of pump performance and mode of operation make speed control a must in many applications.

Some of the applications in which MTRE pumps are used are mentioned below.

Constant pressure

• Washing systems etc.

Example:

Within industrial washing systems, MTRE pumps connected to a pressure sensor ensure a constant pressure in the pipework. From the sensor, the MTRE pump receives input about changes of pressure resulting from changes in the consumption.

The MTRE pump responds to this input by adjusting the speed and thus the pressure. The constant pressure is stabilized once more on the basis of a preset setpoint.

Constant temperature

• Industrial cooling systems etc.

Example:

In industrial cooling systems, MTRE pumps connected to a temperature sensor will ensure a constant temperature and lower operating costs compared to pumps without speed control.

An MTRE pump continuously adapts its performance to the changing demands reflected in the differences in temperature of the liquid circulating in the cooling system. Thus the lower the demand for cooling, the smaller the quantity of liquid circulated in the system and vice versa.

Constant level control

• Condensate systems etc.

Example:

In a condensate system, it is important to monitor and control pump operation to maintain a constant level of condensate in the system.

An MTRE pump connected to a level sensor mounted in the condensate tank makes it possible to maintain a constant liquid level.

A constant liquid level ensures optimum and costefficient operation as a result of a stable production.

Pumped liquids

MTR(E) pumps are designed to pump non-explosive liquids that do not chemically attack the pump materials.

When pumping liquids with a density and/or viscosity higher than that of water, oversized motors may be required.

Whether a pump is suitable for a particular liquid depends on a number of factors of which the most important are the chloride content, pH-value temperature and content of chemicals, oils, etc.

Please note that aggressive liquids may attack or dissolve the protective oxide film of the stainless steel and thus cause corrosion.

Pumping of solid particles

MTR(E) pumps are fitted with a suction strainer. The strainer prevents large solid particles from entering and damaging the pump.

The table below describes the size of the passage in the strainer and the impeller.

If the pumped liquid contains solid particles larger than the size of the holes in the strainer, the passage of the strainer may be blocked. In such situations the performance will drop as a result of a reduced flow through the pump.

Note:

If the strainer is removed from the suction port, solid particles may enter the pump and cause a seizure or even damage the pump.

In grinding applications Grundfos recommends that the pumped liquid is screened for abrasive particles before entering the pump. When pumped, abrasive particles reduce the life of the pump components.

Wear of the pump components caused by abrasive particles starts when the concentration exceeds 20 ppm.

List of pumped liquids

A number of typical liquids are listed in the following table.

Other pump versions may be applicable, but those stated in the list are considered to be the best choices.

The table is intended as a general guide only, and it cannot replace actual testing of the pumped liquids and pump materials under specific working conditions.

The list should, however, be applied with some caution as factors such as concentration of the pumped liquid, liquid temperature or pressure may affect the chemical resistance of a specific pump version.

Safety precautions must be made when pumping dangerous liquids.

MTR(E) product introduction

MTR(E)

MTR(E), MTC, MTA

MTRE

(Pumps with built-in variable frequency drive)

Fig. 1

Grundfos MTR pumps

MTR(E) pumps are vertical multistage centrifugal pumps designed for pumping of cooling lubricants for machine tools, condensate transfer and similar applications.

The pumps can be used for applications involving spark machine tools, grinding machines, machine centers, cooling units, industrial washing machines, filtering systems etc. The pumps are designed to be mounted on top of tanks with the pump stack immerged in the pumped liquid.

Grundfos MTR(E) pumps come with various pump sizes and numbers of stages to provide the flow, the pressure and the length required.

The pumps consist of two main components: The motor and the pump unit. The motor is a Grundfos standard ML motor or Grundfos specified motor designed to NEMA standards.

The pump unit consists of optimized hydraulics, a variety of connections, a motor stool, a given number of chambers and various other parts.

Fig. 2

Grundfos MTRE pumps

MTRE pumps are built on the basis of MTR pumps.

The difference between the MTR and the MTRE pump range is the motor. MTRE pumps are fitted with an

E-motor, i.e. a motor with built-in variable frequency drive (VFD).

The motor of the MTRE pump is a Grundfos MLE motor designed to NEMA standards.

Frequency control enables continuously variable control of motor speed, which makes it possible for the motor to adjust to varying conditions and save energy in the process. Continuously variable control of the motor speed enables adjustment of the performance to a given requirement.

The pump materials are the same as those of the MTR pump range.

Why select a MTRE pump?

Select a MTRE pump if

• controlled operation is required, i.e. consumption fluctuates;

• constant pressure is required

• communication with the pump is required.

Adaptation of performance through frequencycontrolled speed control offers obvious advantages:

• Energy savings

• Increased comfort

• Control and monitoring of the pump performance.

MTR(E) operating conditions

Ambient temperature and altitude

Maximum ambient temperature +104 °F (+40 °C).

If the ambient temperature exceeds +104 °F (+40 °C) or if the motor is located 3280 ft (1000 m) above sea level, the motor output (P

2

) must be reduced due to the low density and consequently low cooling effect of the air. In such cases, it may be necessary to use a motor with a higher output.

MTR 1s, 1, 3, 5 can pump up to 50 cst. MTR 10, 15,

20, 32, 45, 64 can pump up to 100 cst.

The pumping of liquids with densities or kinematic viscosities higher than those of water will cause a considerable pressure drop, a drop in the hydraulic performance and a rise in the power consumption.

In such situations the pump should be equipped with a larger motor. If in doubt, contact Grundfos.

Calculation of the reduced head of a pump with empty chambers

Calculation of pressure loss in empty chambers

From the pressure loss curves and the pump performance curves, it is possible to calculate the reduced head of a pump with empty chambers.

The calculation can be made as shown below.

Example:

Pump type

Flow Q (duty point)

Head (duty point)

MTR 5-18/7

25 [gpm]

180 [ft]

The selected pump is an MTR 5-18/7 with 11 empty chambers. From the above pressure loss curve of

MTR 5, it appears that the pressure loss of each empty chamber at 25 [gpm] is 0.46 [ft]. This results in a total pressure loss of:

Total pressure loss = 0.46 11 = 5 [ft]

The reduced head of the MTR 5-18/7 pump including pressure losses caused by empty chambers is:

Head = 185 5 = 180 [ft]

The head 185 ft is read from the performance curve for an MTR 5-7.

Control of MTRE pumps

Control options for MTRE pumps

Communication with MTRE pumps is possible by means of

• a control panel,

• remote control (Grundfos R100),

• external digital or analog control signals,

• an RS485 bus interface.

The purpose of controlling a MTRE pump is to monitor and control the pressure, temperature, flow or liquid level of the system.

Control panel

The control panel of the MTRE pump terminal box makes it possible to change the setpoint settings manually.

Light fields

MTR(E), MTC, MTA

External control signals

Communication with the MTRE pump is possible even though the operator is not present near the MTRE pump. Communication is enabled by connecting the

MTRE pump to an external control or monitoring system allowing the operator to monitor and change control modes and setpoint settings of the MTRE pump.

Control modes of MTRE pumps

MTRE pumps can be connected to an external sensor enabling control of pressure, differential pressure, temperature, level, differential temperature or flow.

MTRE pumps can be set to two control modes — controlled or uncontrolled operation.

In controlled operating mode the pump is automatically operating according to the desired setpoint of the control parameter. The illustration below shows a pump with flow control as an example of controlled operation.

In uncontrolled operating mode the pump operates according to the constant curve set.

MTR(E) selection and sizing

Selection of pumps

Selection of pumps should be based on

• the duty point of the pump

• sizing data such as pressure loss as a result of height differences, friction loss in the pipework, pump efficiency etc.

• minimum inlet pressure - NPSHR.

1. Duty point of the pump

From a duty point it is possible to select a pump on the basis of the curve charts shown in the chapter of

2. Sizing data

When sizing a pump the following must be taken into account:

• Required flow rate and pressure at the point of use.

• Pressure loss as a result of height differences

(H geo

).

• Friction loss in the pipework (H f

).

It may be necessary to account for pressure loss in connection with long pipes, bends or valves, etc.

• Best efficiency at the estimated duty point.

• NPSHR value.

For calculation of the NPSHR value, see "Minimum

inlet pressure - NPSHR" on page 23.

Efficiency

Before determining the point of best efficiency the operation pattern of the pump needs to be identified.

Is the pump expected always to operate at the same duty point, select an MTR pump which is operating at a duty point corresponding to the best efficiency of the pump.

Dimensional data

Normally, MTRE pumps are used in applications characterized by a variable flow rate. Consequently, it is not possible to select a pump that is operating constantly at optimum efficiency. In order to achieve optimum operating economy, the pump should be selected on the basis of the following criteria:

• The maximum duty point should be as close as possible to the QH curve of the pump.

• The required duty point should be positioned so that

P

2

is close to the max. point of the QH curve.

Between the minimum and maximum performance curves, MTRE pumps have an infinite number of performance curves each representing a specific speed. Therefore it may not be possible to select a duty point close to the max. curve.

Min. and max. performance curves

In situations where it is not possible to select a duty point close to the max. curve, the affinity equations following can be used. The head (H), the flow rate (Q) and the input power (P) are all the appropriate variables you need to be able to calculate the motor speed (n).

Note:

The approximated formulas apply on condition that the system characteristic remains unchanged for n and that it is based on the formula H = k x Q

2 n

and n x

where k is a constant.

The power equation implies that the pump efficiency is unchanged at the two speeds. In practice this is not quite correct.

Finally, it is worth noting that the efficiencies of the frequency converter and the motor must be taken into account if a precise calculation of the power saving resulting from a reduction of the pump speed is wanted.

WinCAPS and WebCAPS

WinCAPS and WebCAPS are both selection programs offered by Grundfos.

The two programs make it possible to calculate an

MTR(E) pump’s specific duty point and energy consumption.

By entering the sizing data of the pump, WinCAPS and

WebCAPS can calculate the exact duty point and energy consumption. For further information see page

106 and page

Minimum inlet pressure - NPSHR

Calculation of the inlet pressure "H" is recommended when ....

• the liquid temperature is high,

• the flow is significantly higher than the rated flow,

• inlet conditions are poor.

To avoid cavitation, make sure that there is a minimum pressure on the suction side of the pump. The maximum suction lift "H" in feet of head can be calculated as follows:

H = p b

– NPSHR – H f

– H v

– H s p b

= Barometric pressure in feet absolute.

(Barometric pressure can be set to 33.9

feet).

In closed systems, p b

indicates the system pressure in feet.

NPSHR = Net Positive Suction Head in feet of head.

(To be read from the NPSHR curve at the highest flow rate the pump will be delivering).

H f

= Friction loss in suction pipe in feet of head.

(At the highest flow rate the pump will be delivering.)

H v

= Vapor pressure in feet.

(To be read from the vapor pressure scale.

"H v

"T m

" depends on the liquid temperature

").

H s

= Safety margin = minimum 2.0 feet.

If the "H" calculated is positive, the pump can operate at a suction lift of maximum "H" feet of head.

If the "H" calculated is negative, an inlet pressure of minimum "H" feet of head is required.

Note:

In order to avoid cavitation, never select a pump whose duty point is too far to the right on the NPSHR curve.

Always check the NPSHR value of the pump at the highest possible flow rate.

Guidelines to performance curves

The guidelines below apply to the curves shown on the following pages:

1. Tolerances to ISO 9906, Annex A, if indicated.

2. The motors used for the measurements are standard Grundfos motors (ML or MLE).

3. Measurements have been made with airless water at a temperature of +68 °F (+20 °C).

4. The curves apply to a kinematic viscosity of

υ = 1 mm

2

/s (1 cSt).

5. Due to the risk of overheating, the pumps should not be used at a flow below the minimum flow rate.

6. QH curves of the individual pumps are based on current motor speeds.

QH curve for the individual pump. The bold curves indicate the recommended performance range for best efficiency.

The eff curve shows the efficiency of the pump.

The eff curve is an average curve of all the pump types shown in the chart.

The efficiency of pumps with reduced-diameter impellers is approx. 2% lower than the curve shown in the chart.

The NPSH curve is an average curve for all the variants shown.

When sizing the pumps, add a safety margin of at least 2 feet.

The curve below shows the minimum flow rate as a percentage of the nominal flow rate in relation to the liquid temperature. Only pumps with EPDM elastomers in the shaft seals can run in the temperature range from +194 °F to +248 °F (+90 °C to +120 °C). Closed strap nuts with o-rings and plugging of the shaft seal drain hole, may also be required at temperatures above +212 °F (+100 °C) (see page

20 ).

Notes:

1. The information in this chart applies to Grundfos

ML motors and Grundfos specified Baldor® motors.

ML motors:

Three-phase, 0.33 Hp to 7.5 Hp

Baldor motors:

Single phase, to 10 Hp; and

Three-phase, 10 Hp to 60 Hp.

Grundfos MTR pumps are supplied with heavy-duty

2-pole, NEMA C-frame motors built or selected to our rigid specifications. All MTR pump motors have heavy-duty bearings in them for maximum thrust requirements.

It is not recommended that an off-the-shelf standard Baldor motor be used on a Grundfos pump. Ideally, the best motor choice would be the Grundfos specified motor.

Baldor motor

ML motor

2. Other motor types are available (i.e., Explosion proof, Mill and Chem duty, High Efficiency, etc.), consult local Grundfos company for more information.

3. Pumps supplied by Grundfos Canada are normally supplied with motors from other manufacturers.

575 volt motors meet EPAct/NRC efficiency standards. Dimensions and data will vary, contact local Grundfos company for more information.

4. All values are subject to change without notice.

MP 204 motor protector

Fig. 32

MP 204

The MP 204 is an electronic motor protector and data collecting unit. Apart from protecting the motor, it can also send information to a control unit via GENIbus, like for instance:

• trip

• warning

• energy consumption

• input power

• motor temperature.

The MP 204 protects the motor primarily by measuring the motor current by means of a true RMS measurement.

The pump is protected secondarily by measuring the temperature with a Tempcon sensor, a Pt100/Pt1000 sensor and a PTC sensor/thermal switch.

The MP 204 is designed for single- and three-phase motors.

Note:

The MP 204 must not be used together with frequency converters.

MP 204 features

• Phase-sequence monitoring

• indication of current or temperature

• input for PTC sensor/thermal switch

• indication of temperature in °F or °C

• 4-digit, 7-segment display

• setting and status reading with the Grundfos R100 remote control

MTC product introduction

MTC pumps are vertical multistage centrifugal pumps designed for pumping of cooling lubricants for machine tools, condensate transfer and similar applications.

Fig. 33

Grundfos MTC pumps

The pumps can be used for applications involving spark machine tools, grinding machines, machine centers, cooling units, industrial washing machines, filtering systems etc. The pumps are designed to be mounted on top of tanks with the pump stack immerged in the pumped liquid.

Grundfos MTC pumps come with various pump sizes and numbers of stages to provide the flow, the pressure and the length required.

The pumps consist of two main components: The motor and the pump unit. The motor is a Grundfos standard ML motor or Grundfos specified motor designed to NEMA standards.

The pump unit consists of optimized hydraulics, a variety of connections, a motor stool, a given number of chambers and various other parts.

 The pump is suitable for this application.

Pumped liquids

MTC pumps are designed to pump non-explosive liquids that do not chemically attack the pump materials.

When pumping liquids with a density and/or viscosity higher than that of water, oversized motors may be required.

Whether a pump is suitable for a particular liquid depends on a number of factors of which the most important are the chloride content, pH-value temperature and content of chemicals, oils, etc.

Please note that aggressive liquids may attack or dissolve the protective oxide film of the stainless steel and thus cause corrosion.

Pumping of solid particles

MTC pumps are fitted with a suction strainer. The strainer prevents large solid particles from entering and damaging the pump.

The table below describes the size of the passage in the strainer and the impeller.

3.6

Impeller passage

[in.]

0.10

0.11

If the pumped liquid contains solid particles larger than the size of the holes in the strainer, the passage of the strainer may be blocked. In such situations the performance will drop as a result of a reduced flow through the pump.

Note:

If the strainer is removed from the suction port, solid particles may enter the pump and cause a seizure or even damage the pump.

In grinding applications Grundfos recommends that the pumped liquid is screened for abrasive particles before entering the pump. When pumped, abrasive particles reduce the life of the pump components.

Wear of the pump components caused by abrasive particles starts when the concentration exceeds 20 ppm.

MTC features and benefits

MTC pumps

MTC pumps are fitted with an integrated Grundfos motor where the rotor shaft is used as pump shaft.

This gives the pump a compact design.

Motors for MTC pumps

MTC motors are totally enclosed, fan-cooled, 2-pole

Grundfos standard motors.

Ambient temperature

Maximum ambient temperature +104 °F (+40 °C).

If the ambient temperature exceeds +104 °F (+40 °C) or if the motor is located 3280 ft (1000 m) above sea level, the motor output (P

2

) must be reduced due to the low density and consequently low cooling effect of the air. In such cases, it may be necessary to use a motor with a higher output.

MTC installation

MTC must be installed vertically.

MTR(E), MTC, MTA

Terminal box positions

As standard MTC pumps have their terminal box mounted in position 6 o’clock of the pump; however other positions are possible.

Note:

On MTC pumps it is not possible to mount the terminal box in position 12 as the terminal box does not fit in that position.

Fig. 37

Installation of an MTC pump

To enable a low liquid level of 1.6 inches above the bottom of the strainer, a priming screw is fitted below the bottom chamber. This helps to protect the pump against dry running down to 1 inch above the bottom of the strainer.

The distance between the pump and tank bottom must be minimum 1 inch.

MTC selection and sizing

Selection of pumps

Selection of pumps should be based on

• the duty point of the pump

• sizing data such as pressure loss as a result of height differences, friction loss in the pipework, pump efficiency etc.

• minimum inlet pressure - NPSHR.

1. Duty point of the pump

From a duty point it is possible to select a pump on the basis of the curve charts shown in the chapter of

"Performance curves/Technical data starting on page

2. Sizing data

When sizing a pump the following must be taken into account:

• Required flow rate and pressure at the point of use.

• Pressure loss as a result of height differences

(H geo

).

• Friction loss in the pipework (H f

).

It may be necessary to account for pressure loss in connection with long pipes, bends or valves, etc.

• Best efficiency at the estimated duty point.

• NPSHR value.

For calculation of the NPSHR value, see "Minimum

inlet pressure - NPSHR" on page 70.

Efficiency

Before determining the point of best efficiency the operation pattern of the pump needs to be identified.

Is the pump expected always to operate at the same duty point, select an MTC pump which is operating at a duty point corresponding to the best efficiency of the pump.

Example of an MTR pump’s duty point

As the pump is sized on the basis of the highest possible flow, it is important always to have the duty point to the right of the optimum efficiency point (see fig.

WinCAPS and WebCAPS are both selection programs offered by Grundfos.

The two programs make it possible to calculate an

MTC pump’s specific duty point and energy consumption.

By entering the sizing data of the pump, WinCAPS and

WebCAPS can calculate the exact duty point and energy consumption. For further information see page

Minimum inlet pressure - NPSHR

Calculation of the inlet pressure "H" is recommended when ....

• the liquid temperature is high,

• the flow is significantly higher than the rated flow,

• inlet conditions are poor.

To avoid cavitation, make sure that there is a minimum pressure on the suction side of the pump. The maximum suction lift "H" in feet of head can be calculated as follows:

H = p b

– NPSHR – H f

– H v

– H s p b

= Barometric pressure in feet absolute.

(Barometric pressure can be set to 33.9

feet).

In closed systems, p b

indicates the system pressure in feet.

NPSHR = Net Positive Suction Head in feet of head.

(To be read from the NPSHR curve at the highest flow rate the pump will be delivering).

H f

= Friction loss in suction pipe in feet of head.

(At the highest flow rate the pump will be delivering.)

H v

= Vapor pressure in feet.

(To be read from the vapor pressure scale.

"H v

"T m

" depends on the liquid temperature

").

H s

= Safety margin = minimum 2.0 feet.

If the "H" calculated is positive, the pump can operate at a suction lift of maximum "H" feet of head.

If the "H" calculated is negative, an inlet pressure of minimum "H" feet of head is required.

QH curve for the individual pump. The bold curves indicate the recommended performance range for best efficiency.

The eff curve shows the efficiency of the pump.

The eff curve is an average curve of all the pump types shown in the chart.

The efficiency of pumps with reduced-diameter impellers is approx. 2% lower than the curve shown in the chart.

The NPSH curve is an average curve for all the variants shown.

When sizing the pumps, add a safety margin of at least 2 feet.

Guidelines to performance curves

The guidelines below apply to the curves shown on the following pages:

1. Tolerances to ISO 9906, Annex A, if indicated.

2. The motors used for the measurements are standard Grundfos ML motors.

3. Measurements have been made with airless water at a temperature of +68 °F (+20 °C).

4. The curves apply to a kinematic viscosity of

υ = 1 mm

2

/s (1 cSt).

5. Due to the risk of overheating, the pumps should not be used at a flow below the minimum flow rate.

6. QH curves of the individual pumps are based on current motor speeds.

The curve below shows the minimum flow rate as a percentage of the nominal flow rate in relation to the liquid temperature. Only pumps with EPDM elastomers in the shaft seals can run in the temperature range from +194 °F to +248 °F (+90 °C to +120 °C). Closed strap nuts with o-rings and plugging of the shaft seal drain hole, may also be required at temperatures above +212 °F (+100 °C) (see page

68 ).

MP 204

The MP 204 is an electronic motor protector and data collecting unit. Apart from protecting the motor, it can also send information to a control unit via GENIbus, like for instance:

• trip

• warning

• energy consumption

• input power

• motor temperature.

The MP 204 protects the motor primarily by measuring the motor current by means of a true RMS measurement.

The pump is protected secondarily by measuring the temperature with a Tempcon sensor, a Pt100/Pt1000 sensor and a PTC sensor/thermal switch.

The MP 204 is designed for single- and three-phase motors.

Note:

The MP 204 must not be used together with frequency converters.

MP 204 features

• Phase-sequence monitoring

• indication of current or temperature

• input for PTC sensor/thermal switch

• indication of temperature in °F or °C

• 4-digit, 7-segment display

• setting and status reading with the Grundfos R100 remote control

• setting and status reading via the Grundfos

GENIbus fieldbus.

Tripping conditions

• Overload

• underload (dry running)

• temperature

• missing phase

• phase sequence

• overvoltage

• undervoltage

• power factor (cos ϕ)

• current unbalance.

Warnings

• Overload

• underload

• temperature

• overvoltage

• undervoltage

• power factor (cos

ϕ)

• run capacitor (single-phase operation)

• starting capacitor (single-phase operation)

• loss of communication in network

• harmonic distortion.

Learning function

• Phase sequence (three-phase operation)

• run capacitor (single-phase operation)

• starting capacitor (single-phase operation)

• identification and measurement of Pt100/Pt1000 sensor circuit.

MTA(H) applications

The MTA(H) pumps are suitable for these applications:

• boring

• sawing

• milling

• grinding

• filtration.

Multiple applications

The compact MTA pumps efficiently transport liquid containing chips, fibers and abrasive particles to the filtering unit. Semi-open impellers allow the passing of chips up to 0.40 inches (10 mm), making the pumps ideal for removing liquid from machining processes.

MTA(H) product introduction

Fig. 47

Grundfos MTA

Grundfos’ MTA range of single-stage immersible pumps has been designed especially for transfer of liquids containing chips, fibers and abrasive particles in filtering systems in the machine tool industry.

These low-pressure pumps are available in nine different variants and come with a choice of top suction or bottom suction.

The pumps are designed to be mounted on top of tanks with the pump part immersed into the pumped liquid.

The pump is designed to be maintenance free, and therefore does not contain shaft seals or other wear parts.

• product photos

• dimensional drawings

• wiring diagrams

• quotation texts, etc.

Literature

In this section you can access all the latest documents of a given pump, such as

• product guides

• Installation and operating instructions

• service documentation, such as Service kit catalog and Service kit instructions

With a starting point in different application areas and installation examples, this section gives easy step-by-step instructions in how to

• select the most suitable and efficient pump for your installation

• carry out advanced calculations based on energy consumption, payback periods, load profiles, life cycle costs, etc.

• analyze your selected pump via the built-in life cycle cost tool

• determine the flow velocity in wastewater applications, etc.

Replacement

In this section you find a guide to select and compare replacement data of an installed pump in order to replace the pump with a more efficient Grundfos pump.

The section contains replacement data of a wide range of pumps produced by other manufacturers than Grundfos.

Based on an easy step-by-step guide, you can compare

Grundfos pumps with the one you have installed on your site.

After having specified the installed pump, the guide suggests a number of Grundfos pumps which can improve both comfort and efficiency.

CAD drawings

In this section it is possible to download 2-dimensional (2D) and

3-dimensional (3D) CAD drawings of most Grundfos pumps.

The following formats are available in WebCAPS:

2-dimensional drawings

• .dxf, wireframe drawings

• .dwg, wireframe drawings.

3-dimensional drawings

• .dwg, wireframe drawings (without surfaces)

• .stp, solid drawings (with surfaces)

• .eprt, E-drawings.

WinCAPS is a Windows-based Computer Aided

P

roduct Selection program containing detailed information on more than 220,000 Grundfos products in more than 22 languages.

The program contains the same features and functions as WebCAPS, but is an ideal solution if no Internet connection is available.
