D-PPC high quality duplex pressure control panel is built to maintain water pressure in various systems. Specifically designed by Northwest Tech-Con Systems, they are part of a booster control panel series, for use with a complete line of pressure pumps to provide maximum protection efficiency for all models. A low voltage control module is used to operate the starting, stopping, and alternation of the pumps, with one pump operating to handle normal pressure. A second pump becomes operational when system pressure is too low. A built-in alarm system in the control module also operates when the suction pressure is low. In the case of a duty pump being switched off under overload, high temperature, seal leakage, etc., the controller will automatically start the lag pump.
