Product Lines
NightEye Series
The NightEye Series is Liberty Pumps' connected battery backup sump pump system, designed for residential installations where continuous protection during power outages is the primary concern. NightEye integrates Wi-Fi monitoring with battery backup operation, sending alerts when the primary pump activates or backup power engages. It differs from a high-capacity primary sump pump in that its design priority is outage protection and remote notification rather than maximum gallons-per-minute output.
StormCell Series
The StormCell Series is a high-capacity sump pump system built for residential properties with heavy water intrusion or high water table conditions. StormCell units combine cast iron construction with high-efficiency impellers to deliver elevated GPM performance as the primary defense against flooding. Contractors working on properties where a standard residential sump pump hasn't kept pace with water volume commonly specify the StormCell Series.
LSS-Series Commercial Wastewater Pumps
The LSS-Series is Liberty Pumps' commercial submersible wastewater pump line, engineered for continuous-duty applications in apartment buildings, lift stations, and municipal wet wells. LSS-Series pumps handle higher solids content and heavier duty cycles than residential sewage pump lines. Contractors specifying for commercial drainage infrastructure select the LSS-Series for its construction and extended-run capabilities.
LSG300-Series Grinder Pumps
The LSG300-Series is a commercial grinder pump line that macerates waste solids prior to pumping through small-diameter force mains. The LSG300-Series is appropriate for low-pressure sewer systems, pressure sewage applications, and below-grade installations where gravity drainage to the main sewer line isn't feasible. Where the LSS-Series passes solids through, the LSG300-Series grinds them down for pressure-main compatibility.
LNV-Series Battery Backup and Inverter Systems
The LNV-Series provides inverter-based battery backup engineered to power Liberty Pumps sump systems through utility outages. LNV-Series units integrate with AC-powered primary sump pump installations and provide sustained backup runtime based on cycle frequency and depth of discharge. The LNV-Series functions as a complement to primary sump pump systems rather than a standalone pumping solution.
Why Contractors Specify Liberty Pumps
Liberty Pumps holds ISO 9001 certification and manufactures over 90% of its product line in Bergen, New York. Trade professionals specify Liberty Pumps for the consistency of a domestically controlled manufacturing process and the depth of a catalog that covers residential, light commercial, and industrial drainage applications. The brand has been actively manufacturing in the United States since 1965, and its product line has expanded to meet evolving code requirements across sump, sewage, grinder, effluent, and drain applications. Macerating toilet systems and engineered pump packages are part of the same catalog, making Liberty Pumps a single-source option for plumbing contractors handling full residential drainage scope.
FAQs
- Where are Liberty Pumps products manufactured?
- Liberty Pumps products are manufactured in Bergen, New York. The company is a family and employee-owned domestic manufacturer, with over 90% of its product line produced in the United States.
- What warranty does Liberty Pumps offer on its sump and sewage pumps?
- Liberty Pumps warranty terms vary by product line. Specific warranty documentation is available through Liberty Pumps' official product pages, installation manuals, and their wholesale warranty policy.
- What's the difference between the NightEye Series and the StormCell Series?
- The NightEye Series is a battery backup sump pump system designed for outage protection, with Wi-Fi monitoring that sends alerts when the primary pump or backup engages. The StormCell Series is a high-capacity primary sump pump system built for heavy water intrusion that demands higher GPM output. NightEye protects against power outages; StormCell addresses high-volume primary pumping requirements.
- What size Liberty Pumps sump pump is right for a residential installation?
- Residential pump sizing depends on water intrusion volume, pit depth, and discharge line height. Standard Liberty Pumps submersible sump pump models cover typical residential drainage loads. Properties with persistent flooding or high water table readings may benefit from the higher-capacity StormCell Series.
- Are Liberty Pumps sewage pumps compatible with 4-inch discharge piping?
- Discharge connection sizing for Liberty Pumps sewage pump models depends on the specific unit. Installers should confirm discharge port sizing and plumbing compatibility against the product specification sheet and installation manual for the model being installed.
- What size grinder pump is right for a below-grade bathroom application?
- Grinder pump sizing for below-grade bathroom applications using the LSG300-Series depends on the number of fixtures, the discharge run length, and the total required head. Liberty Pumps' engineering documentation and pump curve reference materials provide model-specific guidance for these calculations.
