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.

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!
