12V Battery Back-Up Sump Pump System w/ Alarm

The 441 from Liberty Pumps is a Battery Back-Up Sump Pump System w/ Alarm, 12V.  It is designed only as a temporary means of pumping when a primary sump pump has problems with normal operation. The Liberty 441 is not intended to be used as the main sump water removal pump. The Liberty Pump 441 is a high output, submersible pump with an automatic, mercury-free switch. It comes equipped with a control panel, battery box, 12V charger and 1-1/2" or 1-1/4" connections.

The Liberty 441 features an advanced 5-stage charging system. This system tests the battery and maintains a maximum charge without running the battery down or self-discharging. A sophisticated charging algorithm continuously tests the charging process from start to finish. The frequency of pump cycle, length of running time and pumping head will vary the lifetime of battery operation. Under a continuous-run situation, the battery will last up to 4 hours and up to 30 hours in intermittent operation.

This backup sump pump system is not to be used on flammable liquids or chemicals, only use to pump clear water. The battery charger for the Liberty Pump 441 must be kept dry and away from damage.
