Constant Pressure System

The CP Water Subdrive 75 from Franklin Electric provides constant water pressure by continually adjusting the pump speed to meet water demand and also eliminates pressure cycling during long-running applications such as lawn sprinkling and geothermal heat pump operation. The Subdrive 75 uses a standard 3⁄4-HP pump and a 11⁄2-HP, 3-phase motor, and is used on applications including residential water systems, geothermal systems, lawn irrigation systems and water treatment systems.
