INSIDE
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 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 maximized by state-of-the-art hydraulic design and carefully crafted production technology.
Durable bearings
The CR bearings are remarkable 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, stainless steel AISI316, stainless steel AISI 304 and AISI 304/cast iron.
Wide range of sizes
The CR comes in 13 flow sizes and hundreds of pressure sizes, ensuring that you can always find exactly the right pump for the job.
RELIABILITY
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.
EFFICIENCY
Reduce the real cost
Electricity is the most expensive part of any pump. This simple fact is often overlooked when pumps and prices are compared, so it is worth repeating here.
It may still surprise some to learn that the purchase price and maintenance costs account for less than 15% of the total lifetime cost of a pump. Obviously, this means that electricity accounts for a staggering 85% or more of the total costs. So if you want to save money, that’s why you should look at.
