A Smart Way to Save

COOL AND CONVINCING

Grundfos CRE-pumps are your all-in-one energy saving solution: a pump and motor with an integrated frequency converter, controller and sensor.

Grundfos CRE-pumps offer all the advantages of a total system integration. They come with an integrated frequen-cy converter, PID controller and, in some models, pressure or differential pressure sensor.

The pump, motor, frequency converter, PID controller and sensor are perfectly matched, tested and configured at the factory, which greatly facilitates the subsequent installa-tion and commissioning.

An E-pump solution constitutes the ideal variable-speed solution for all types of industry and building applications.

GRUNDFOS CRE-PUMP FEATURES

> Compact plug-and-pump solution

> Factory configured and tested units

> Limited on-site settings

> Easy installation and commissioning

> User-friendly interface

> Advanced features and functionality

> Remote control and monitoring via bus interface and R100 control

E-PUMP AVAILABILITY

FLEXIBILITY AND FUNCTIONALITY

The Grundfos CUE is your ideal solution: a wall-mounted frequency converter, which has E-pump functionality.

CUE solutions cover most pump types, application areas, and power ranges outside the E-pump range.

A CUE solution is a great fit in situations where an inte-grated solution is either undesirable or prohibited - such as sanitary and hazardous areas.

The CUE solution offers you a space-saving installation, the freedom of choice, and speed-control functionality with new or existing Grundfos pumps.

GRUNDFOS CUE FEATURES

> E-pump functionality

> Start-up installation guide

> Automatic setting of rotation direction during installation

> Integrated display with an easy-to-use R100 style menu

> Constant pressure or level control with stop function

> Dedicated functions for groundwater applications

> Remote control and monitoring via bus interface

UPSIZING ENERGY EFFICIENCY

GRUNDFOS CR SOLUTIONSThe CR range from Grundfos

Grundfos was the first company to develop a multi-

stage in-line pump, and today the CR remains second

to none. It is the most extensive in-line pump program

on the market, matching customer requirements with

many innovative features unique to Grundfos. CR

provides superior reliability and the lowest possible

cost of ownership to customers worldwide.

Impressive as the CR range is, Grundfos offers much

more. Our complete range of pump solutions means

that you can rely on Grundfos know-how and our

Being responsible is our foundation

Thinking ahead makes it possible

Innovation is the essence

> Motor

Grundfos provides many motor solutions depending upon

the application and demand. In addition, Grundfos makes

its own motors to ensure maximum performance. The ML

motors* are remarkably quiet and highly efficient. They are

also available in the self-regulating MLE configuration, fea-

turing an integrated variable frequency drive.

> Cartridge seal

The specially designed cartridge seal increases reliability,

ensures safe handling and enables easy service and access.

> Shaft seal solutions

The cartridge shaft seal configuration comes in a wide

choice of materials. It is available in flushed seal and

double seal configurations as well as a Cool-top version

that can handle temperatures up to +356°F (+180°C).

> Connection options

The Grundfos CR can be connected to any piping system.

> Dry-running sensor

The patented Grundfos LiqTec™ system eliminates the risk

of breakdowns due to dry running. If there is no liquid in the

pump, the LiqTec will immediately stop it.

> High-performance hydraulics

Pump efficiency is maximized by state-of-the-art hydraulic

design and carefully crafted production technology.

> Durable bearings

The CR bearings are remarkably long-lived thanks to

hardwearing materials and a wide range of options for

difficult liquids.

> Material options

The CR is available in four different materials: AISI 304/

cast iron, stainless steel AISI 304, stainless steel AISI 316,

and titanium.

> Wide range of sizes

The CR comes in 13 hydraulic sizes and hundreds of pres-

sure sizes, ensuring that you can always find exactly the

right pump for the job.

> CR, CRN 120 and 150

The newest addition to the CR family nearly doubles our

maximum Hp adding 75 and 100 Hp models. Its maximum

flow is nearly 800 gpm.

Innovation Inside the CR

To many, innovation is just a buzzword. At Grundfos,

innovation is an integrated feature of all our products.

After all, it’s what’s inside that matters.

* Grundfos ML motors are not available in Canada.

Grundfos was the first pump manufacturer ever to create a multi-stage in-line

pump. Known as the CR pump, this innovative design has inspired followers all

over the world. Even so, continuous development and innovation ensure that the

Grundfos CR remains unmatched.

The CR of today reflects the needs and requirements of customers worldwide. We

know this, because we asked you first! Read on to learn about our comprehensive

CR range, including our new extra-large CR featured on pages 6 and 7.

The complete Grundfos CR range: The last word in multi-stage pump technology

Choosing the right pump can be difficult. It may be easy enough to find a pump

that will do the job, but it gets trickier when you want an exact match. There

are many good reasons to avoid over-capacity, with energy conservation at the

top of the list. The CR range lets you choose pumps which exactly match your

system demands.

The CR is available in 13 hydraulic sizes, four basic materials and over one million

configurations. For more information on the many options to provide you with the

right solution for your system demands, see pages 12 and 13.

To meet the growing demand of customers requiring a pump-

ing system to handle higher flow rates for vast system demand,

Grundfos now offers the renowned CR in a “super-sized” capac-

ity. With nearly double the horsepower, the new extra-large

CR offers extended efficiency to meet your high-flow system

demands.

With a maximum flow of nearly 800 gpm, the scope of the

Grundfos CR range now provides the pump industry with the

most comprehensive flow range on the market today. When cou-

pled with CR reliability, the extra-large CR rounds out the range

with a high flow solution second-to-none.

> Nearly double the CR horsepower range

> Flows up to 792 gpm

> Spacer coupling on full range (seal changes without

disturbing motor)

> Standard 22 mm cartridge shaft seal on models up to

60 Hp (32 mm cartridge shaft seal on 75 Hp and 100

Hp models)

> Custom-built solutions
