ECV Variable Speed Fire Pump Controllers
- Product Information
The Variable Speed Controller works by varying the speed of the motor depending on the demand of the pump. It
is best thought of as cruise control: if you encounter a hill, the car automatically speeds up to compensate for it.
The opposite is also true, and this is exactly how a VFD Drive works.
Through precise and careful engineering we are able to set the pressure setting to anything you want, and keep it
there within 1 psi.
- You may be thinking, "How well does this really work?" Watch the Overview of Variable Speed video to
see our Variable Speed Controller in action.
The reliability of our Variable Speed Controller is also phenomenal. It will normally start
with the Variable Frequency Drive, but as a precaution, if it does not turn on within a set amount of time the controller switches
over to bypass mode. If your Variable Speed Fire Pump Controller has a reduced voltage starting method, it will
use this first, and then go across the line. This means our Variable Speed Controller has 3 entirely separate
starting methods, while normal reduced voltage controllers only have 2!
