Product Overview

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.
To many, innovation is just a buzzword. At Grundfos, innova-
tion is an integrated feature of all our products. After all, it’s
