NBS / NBSE, END-SUCTION SPLIT-COUPLED
NBS, NBSE are split-coupled end-suction pumps that are part of the N-series that offers a Lifetime Alignment Guarantee and a revolutionary hard-faced seal.
Lifetime Alignment from Grundfos Saves You Money
Did you know that only 7% of measured machines fall within acceptable alignment tolerances, leaving 93% of machines experiencing problems caused by misalignment, including:
- Increased energy consumption: As little as a 1.25mm offset can cause an 8% increase in energy consumption.
- Premature seal and bearing failure: Even just a 0.05mm offset reduces the seal wear life by 90%.
That is why Grundfos has engineered pumps like this to include a Lifetime Alignment Guarantee which will save you money and time over the lifetime of equipment.
See Why The Right Innovation Means Less Complexity
We’re designing smarter HVAC pumping solutions that use data to control, optimize and adapt your entire system, without your intervention. And we’re delivering it in a complete, simplified setup that saves you time and energy.
Controls are the key to making sure the commercial heating system is operating properly. With intelligent controls from Grundfos, you will find it easy to collect and analyse data from across the system and use that data to control the energy used to run the system against real-time demand.
By using this approach, you can make sure that every dollar you spend on your commercial heating system is well spent. And just as importantly, you can operate the system with greater efficiency than ever before, so you may find that you make real savings during the lifetime of the system.
Our approach is simple with:
- Advanced design
- Precise control
- Ongoing optimization
