Liberty Pumps Automatic 12V Emergency Sump Pump System
The Liberty Pumps 441 Battery Back-Up Emergency Sump Pump System provides essential, round-the-clock protection against basement flooding during a power outage or primary pump failure. This 12-volt system automatically activates the moment your 120V primary pump loses power, ensuring your sump pit continues to be emptied. The system includes a high-output 12V submersible pump, a control panel with an audible alarm and warning light, and a smart 1.5A switch-mode charger.
Designed for reliability, the 441 features a compact, mercury-free vertical float switch for automatic operation, making it ideal for most sump pits. The innovativo charger maintains your battery (sold separately) at peak condition without overcharging. For a complete flood-prevention setup, explore our full range of battery backup sump systems.
