Liberty's LCU-N20ST is an LCU-Series neutralizing condensate pump — pairs the standard condensate pump with a neutralizer cartridge that raises the pH of acidic condensate from high-efficiency condensing furnaces and boilers before it's discharged, as required by some local codes. Fully automatic with a built-in safety switch, wired for 115V, and includes 20' of discharge tubing. It has a high-impact ABS tank, a stainless steel shaft, permanently lubricated bearings, and a hermetically sealed, thermally protected, quiet-running motor.
