the Inside story
Grundfos motor Grundfos makes its own motors to ensure maximum performance. 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, ensures safe handlingand 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 ofbreakdowns 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 hardwearing materials and a wide range of options for difficult liquids. Material optionsThe CR is available in four different materials: titanium, stainless 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.

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.

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 oftoday reflects the needs and requirements of customers 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 improvements provide:

superior reliability Unmatched cost efficiency the most extensive range on the market
The new generation of Grundfos CR pumps features a full range ofsizes and limitless scope for combinations to suit your specific needs. At Grundfos, innovation is about making things better. And we focus our effort where it matters: inside.

RelIabIlIty

It’s reliable. and we can prove it.

The boiler feeding process reads like a shortlist of extreme pump conditions: high temperatures, long operating hours, frequent starts/stops, pressurepulsing, 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 unsurpassedreliability: dry-running protection, a unique cartridge seal, and a fulltitanium variant. Extreme conditions call for extreme reliability. Less demanding applications need fewer special features. The virtually endless range of standard and customised CR pumps means that you can always find the right pump, no matter what your requirements may be. superior dry-running protection Dry running is the mostcommon cause of pump failure. In most pumps, the shaft seal and bearings will burn out almost immediately if liquid stops flowing in the pump. The Grundfos CR is different. As part of our constant dedication to innovation, we have tested new and alternative materials to bring you the best possible solution. This means that we can equip CR pumps with a shaft seal and bearing system that can...
