FAQS

Frequently Asked Questions

What is the main advantage of an ECM motor pump?
An ECM motor is significantly more efficient than a standard motor, especially at partial loads where HVAC systems operate most of the time. This translates to massive energy savings. It also allows for precise variable speed control without needing a separate VFD.
Proper sizing requires calculating your system’s required flow rate (GPM) and head loss (feet). Our application engineers can assist you with this analysis, or you can use our pump selection software to find the most efficient model for your calculated duty point.
Our smart pumps offer native support for common protocols like Modbus and BACnet, allowing for direct communication and control with most building automation systems right out of the box.
