This controller provides constant water pressure using state of the art electronics to drive and enhance the
performance of a standard submersible pump. The pressure in a well system is monitored and regulated by
the pressure sensor to continually adjust the pump motor speed to meet water supply demands. It eliminates
the pressure cycling associated with a conventional well system. SubDrive can deliver dependable constant
pressure to provide water well owners with a premium water system.
