Liberty Pumps LCU-N220ST 230V Neutralizing Condensate Pump With Safety Switch and Tubing

Liberty Pumps LCU-N220ST Neutralizing Condensate Pump

The Liberty LCU-N220ST is a high-voltage neutralizing condensate pump designed for international and commercial applications requiring 230V power. It safely neutralizes acidic condensate from high-efficiency furnaces, boilers, and water heaters using a replaceable magnesium oxide media cartridge, while also handling non-acidic condensate from A/C units, dehumidifiers, or ice machines via dedicated inlet ports. With its built-in overflow safety switch and included 20 ft tubing, the LCU-N220ST provides a complete, code-compliant solution.

Key Features & Benefits

• 230V Power — suited for international installs and commercial systems requiring higher voltage.
• Neutralizer Cartridge — granular magnesium oxide media elevates pH of acidic condensate for safe disposal. 
• Multiple Inlet Paths — three 1" inlets for non-acidic condensate; dedicated 1" and ¾" inlets for acidic lines. 
• Overflow Safety Switch — protects against pump failure or blocked discharge lines.
• Removable Check Valve — simplifies maintenance and replacement. 
• Compact & Quiet — thermally protected motor with vibration isolation pads. 
• Includes 20 ft Tubing — flexible setup straight out of the box.

Applications & Use Cases

• Neutralizing acidic condensate from high-efficiency boilers, furnaces, or water heaters (up to 500,000 BTU input)
• Pumping non-acidic condensate from A/C units, dehumidifiers, and ice machines
• Commercial or international installations requiring 230V operation

Maintenance & Replacement

• Replace neutralizer media cartridge (part # K001898) annually or when condensate pH drops below safe levels.
• Inspect check valve, inlet fittings, and overflow safety switch during routine service.
• Always install with proper air gap and per local code for condensate drainage.
