Constant Pressure Controls offer the user “city” like pressure on remote locations, and offer consistent coverage on irrigation systems. They operate the pump at the most efficient point to facilitate the demand, and create cost savings in the electrical operation of the pump. Constant Pump Controls also prolong the life expectancy of a pump and motor, by not operating at full speed when it is not required. Constant Pressure Controls can be applied to both submersible and above ground applications. They are also available in single phase and three phase configurations.
