Grundfos CR | Innovation Inside
The Inside Story

Grundfos motor
Grundfos makes its own motors to ensure maximum per¬formance. The MG
motors are remarkably silent and highly efficient. They are also available in the
self-regulating MGE configuration, featuring an integrated frequency converter.

Cartridge seal
The specially designed cartridge seal increases reliability, en¬sures 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, double seal and magnetic drive configurations.
Handles temperatures from -40°C to 180°C.

Connection options
The Grundfos CR can be connected to any 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 maximised by state-of-the-art hydraulic design and carefully
crafted production technology.

Durable bearings
The CR bearings are remarkably long-lived thanks to hard¬wearing materials
and a wide range of options for difficult liquids.

Material options
The CR is available in four different materials: titanium, stain¬less steel AISI
316, stainless steel AISI 304 and AISI 304/cast iron.

Wide range of sizes
The CR comes in 11 flow sizes and hundreds of pressure sizes, ensuring that
you can always find exactly the right pump for the job.
The complete Grundfos CR range:
The last word in multistage pump technology
Grundfos was the first pump manufacturer ever to create a multistage 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 cus¬tomers worldwide. We know this, because we
asked you first. All development work at Grundfos is carried out with the end-users in mind; never for its
own sake. The latest improve¬ments provide:

> Superior reliability
> Unmatched cost efficiency
> The most extensive range on the market

The new generation of Grundfos CR pumps features a full range of sizes and limitless scope for
combinations to suit your specific needs. At Grundfos, innovation is about mak¬ing things better. And we
focus our effort where it matters: INSIDE.
The boiler feeding process reads like a shortlist of extreme pump conditions: high
temperatures, long operating hours, frequent starts/stops, pressure pulsing, and poor inlet
conditions. This makes it even more remarkable that the Grundfos CR is the first choice for
such operations worldwide.
Reliability in real life
The CR is renowned for its reliability. And rightly so. The CR
design has all the durability that customers expect from a high-
quality multistage pump – and then some. We have added
unique features to ensure unsurpassed reliability: dry-running
protection, a unique cartridge seal, and a full-titanium variant.

Extreme conditions call for extreme reliability. Less
demand¬ing applications need fewer special features. The
virtually endless range of standard and customized CR pumps
means that you can always find the right pump, no matter
what your requirements may be.
