The CR is renowned for its reliability. And rightly so. The CRdesign has all the durability that customers expect from ahigh-quality multistage pump – and then some. We haveadded unique features to ensure unsurpassed reliability:dry-running protection, a unique cartridge seal and a fulltitanium 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.
• Efficiency Class 1 motors – the best efficiency you can get The Grundfos CR makes a real different. All 3-phase 50Hz motors used in the CR range bear the EFF1 mark; clear proof that they are as efficient as pump motors can get. See the table below to find out just how much electricity you can save
• Other benefit of EFF1 pumps. While energy savings are the main benefit of EFF 1 motors, it’s worth noting that they are also quieter than standard motors –they require less cooling, so their fans are smaller and less noisy.The lower motor temperature also means that EFF1 motors tolerate higher ambient temperatures up to 60°C.
