Like a conventional pump system, a constant pressure system requires a pump, a pressure tank, and a pressure switch or sensor. The pressure sensor monitors a system’s pressure and sends a signal to the control panel for the pump. A controller then signals the pump to perform at a rate required to maintain an optimized pressure and volume. The pressure setting may be adjusted at either the pressure sensor or motor controller depending on the system.
The pressure tank in a constant pressure system is typically much smaller than in a conventional system. It stores very little water, acting primarily as a buffer to prevent pressure fluctuations.
The pumps used are similar to those in a submersible system. The difference is the motor attached to the pump runs at variable speeds depending on water demand. The motor speed is controlled by a variable frequency drive controller.
