CP150 constant pressure pump systems.
3 HP Constant Pressure Systems for Irrigation and Deep Well Applications
The Commander Pro 150 series of pre-packaged constant pressure water systems is designed specifically for demanding applications. Seven models engineered to provide a constant pressure water supply from as deep as 1200' or at flows from 2.7 to 73 gpm at 50 psi. These system packages are ideal for use in residential and light commercial applications, including large homes, deep wells, ground source heat pumps, lawn irrigation systems and water features. Features include dependable 4" submersible pump technology, single-phase power input and the innovative Franklin Subdrive 150 variable speed controller. These systems are designed to reduce total equipment costs, as large bulky tanks, external motor protection devices and complicated adjustments are no longer required.
