LIBERTY PUMPS

Liberty Pumps is a US-based manufacturer of pumps and pump control systems, founded in 1965 and headquartered in Bergen, New York. The company produces submersible sump, sewage, effluent, and grinder pumps, along with a range of control panels, floats, and switches. Its product line is used in residential, commercial, and industrial fluid-handling applications, including wastewater transfer, dewatering, and sewage ejection. Liberty Pumps is known for its vertical integration, with in-house engineering and manufacturing of key components such as motors, castings, and controls. The brand's control panels are designed for single-phase and three-phase operation, with voltage ratings from 120V AC up to 575V AC and current ranges spanning 0–20 A and beyond. Many panels feature tether floats for level sensing, demand dose scheduling, and audio or visual alert outputs. Enclosures are available in plastic or metal, with outdoor-rated options for exposed installations. 3G Electric supplies Liberty Pumps control panels and related accessories globally. The panels we stock include simplex and duplex configurations, alternating or non-reversing operation, and compatibility with a range of pump sizes. These panels are used in applications where reliable pump cycling and fault notification are required, such as wastewater treatment, sump pits, and industrial process water. Our inventory includes models with 120/208/240V AC, 200/230V, 208/240/480V, and 575V AC ratings, covering current ranges from 0–14.9 A up to 18.5 A. We also carry panels with demand dose dosing schedules, which allow for controlled effluent dosing in systems with timed or volume-based requirements. For technical buyers, Liberty Pumps control panels offer selectable alternation, float-based level control, and alert outputs that can be tied to building management or alarm systems. The panels are designed for indoor and outdoor use, with plastic enclosures that resist corrosion in damp environments. 3G Electric supports the Liberty Pumps line by maintaining stock of control panels and providing specification assistance for voltage, current, and enclosure requirements. Our team can help match a panel to a specific pump or system configuration, ensuring compatibility with existing floats and alarm circuits. We ship globally, serving plant engineers, maintenance managers, and procurement specialists who need documented, spec-ready components. Whether you are replacing a failed panel or specifying a new installation, we can provide the technical data needed to select the correct model. Liberty Pumps also manufactures pumps, but our current focus for this line is on the control panels and accessories that support sump, sewage, and grinder pump systems. For applications requiring duplex alternation, demand dosing, or high-voltage operation, the Liberty Pumps control panel range provides a structured set of options. We encourage buyers to review the voltage, current, and enclosure ratings carefully, as these determine compatibility with the pump and the installation environment. 3G Electric can supply datasheets and wiring diagrams upon request to aid in verification.

Frequently asked questions

Common questions about LIBERTY PUMPS from 3G Electric.

What voltage and current ratings are available in Liberty Pumps duplex control panels?

Liberty Pumps duplex control panels are available in several voltage and current configurations. Common ratings include 120/208/240V AC with 0–14.9 A or 15–20 A, 208/240/480V AC with 1.6–2.5 A or 2.5–4 A, and 575V AC with 2.5–4 A or 4–6.3 A. These panels manage two pumps with alternating operation, and many include tether floats for level sensing. The current range determines the maximum pump load the panel can handle. When selecting a panel, match the voltage to the site supply and the current range to the pump's full-load amperage. 3G Electric stocks these configurations and can provide spec sheets for verification.

How does the demand dose feature work on Liberty Pumps simplex control panels?

Demand dose is a dosing schedule used in Liberty Pumps simplex control panels to control effluent pumping based on demand. The panel uses a tether float to sense liquid level and activates the pump when a set level is reached. The demand dose logic allows the pump to run for a calculated period or until the level drops to a lower setpoint, depending on the model. This is common in applications where timed dosing or volume-based dosing is required, such as septic effluent systems. The panel may include an audio or visual alert output for fault conditions. 3G Electric supplies simplex panels with demand dose, including models rated 120/208/240V AC at 15–20 A and 200/230V at 18.5 A.

What enclosure types are used for Liberty Pumps control panels?

Liberty Pumps control panels are available in plastic and metal enclosures. Plastic enclosures are common for outdoor-rated models, providing corrosion resistance in damp or exposed environments. Some panels are specifically marked for outdoor use, while others are intended for indoor installation. The enclosure type affects the panel's suitability for a given location, so it is important to verify the rating against the installation site. For example, a panel with a plastic outdoor enclosure can be mounted in a sump pit area or wastewater treatment room where moisture is present. 3G Electric stocks panels with both indoor and outdoor plastic enclosures, and can advise on the appropriate choice based on the environment.

Can Liberty Pumps control panels be used with grinder pumps?

Liberty Pumps control panels are designed for use with a range of pump types, including grinder pumps. The panel's current rating must be compatible with the grinder pump's full-load amperage. For example, a panel rated 0–14.9 A or 15–20 A at 120/208/240V AC can control single-phase grinder pumps within that current range. Duplex panels with alternating operation are often used in systems with two grinder pumps for redundancy. The panel's float type and alert output should also match the system requirements. 3G Electric supplies Liberty Pumps panels that are commonly paired with grinder pumps in wastewater and sewage applications. Always confirm the pump's electrical characteristics before selecting a panel.

What is the difference between simplex and duplex Liberty Pumps control panels?

Simplex Liberty Pumps control panels control one pump, while duplex panels control two pumps. Duplex panels typically include alternating operation, which switches the lead pump on each cycle to distribute wear evenly. They may also have demand dose scheduling and multiple float inputs for level control. Simplex panels are used in single-pump systems and can include demand dose for timed or volume-based dosing. Both types are available in various voltage and current ratings, and with audio or visual alert outputs. The choice depends on the system design: simplex for single-pump installations, duplex for systems requiring redundancy or higher capacity. 3G Electric stocks both configurations.

What alert output options are available on Liberty Pumps control panels?

Liberty Pumps control panels offer audio and visual alert outputs. Audio alerts provide an audible alarm for fault conditions such as high water level or pump failure. Visual alerts use an indicator light or display to signal the same conditions. Some panels include both, while others have one type. The alert output can often be connected to a remote alarm panel or building management system for monitoring. When selecting a panel, consider whether the installation requires local notification or remote signaling. 3G Electric supplies panels with audio, visual, or combined alert outputs across the range of voltage and current ratings.
