Liberty Pumps Simplex Pump Control Panel 120/208/240V

The Liberty Pumps Simplex Control Panel is designed for single-pump applications on 120/208/240V, 1 phase, with a NEMA 4X enclosure and a 15-20 amp range. Its across-the-line magnetic contactor and a straightforward Test/Auto switch support simple operation and quick troubleshooting. This option is best for homeowners or small facilities that need a reliable, weatherproof control panel with easy wiring through a terminal block.
Who it’s best for: residential basements or light commercial settings where a durable, easy-to-wire control panel is valued. Why selected: robust enclosure and simple, direct control features suit non-technical installers seeking dependable operation. Limitation: limited to the specified voltage and amperage range; not ideal for higher-current pumps.
Pump Control Panel with High Water Alarm (Model 50B010 WHAP)

This panel adds a high-water alarm to a standard pump control setup, making it well-suited for basements, crawl spaces, or other flood-prone areas. It includes circuit breakers for both pump and alarm circuits, an accessible terminal block, and an externally mounted run/mute/test switch with a UV-resistant sealing boot. It’s a solid fit for users who need audible or visual alerts and simple maintenance access.
Who it’s best for: environments requiring proactive flood alert capabilities and rapid service access. Why selected: the alarm integration and external switch improve safety in vulnerable locations. Limitation: the external components may require careful weatherproofing in extreme conditions.
Single Phase Simplex Pump Control Panel SAS-S-1PH-30

From Sasquatch Controls Store, this UL-listed single-phase control panel supports 120/208/240V with a 0.0-25.0 FLA range and includes motor and control circuit breakers. It is suitable for installations where UL listing and a compact, integrated control solution matter. Choose this if you require formal listing and a compact design for constrained spaces.
Who it’s best for: installers and facilities needing UL-listed protection and a compact footprint. Why selected: UL listing provides an extra layer of compliance, and the wide voltage compatibility helps in mixed electrical environments. Limitation: capacity is driven by FLA range and may not suit high-load pumps.
208/240/480V Simplex Control Panel (3 Float)

This model supports higher voltage options (208/240/480V) for single-phase systems with three float sensors and a 35 ft. cord, ideal for larger sumps or basins requiring float-based control logic. It’s best for facilities that need automatic shutoff and level sensing across multiple points. Choose this if you operate at higher voltages or require additional float redundancy. Limitation: higher voltage panels may demand more complex wiring and installation considerations.
Dayton Simplex Control Panel (2PZF8)

The Dayton panel provides a United States–made option for simplex control with standard enclosure features. It suits budget-conscious projects that still require reliable single-pump management. Best for: straightforward, cost-effective pump control setups in residential or light commercial contexts. Limitation: fewer advanced features compared to higher-end models.
Buying Guide
What to consider when choosing a simplex pump control panel:
- Voltage and current range: Ensure the panel supports your pump’s voltage (120/208/240V) and full-load amps (FLA). Some models are optimized for specific ranges.
- Enclosure type: NEMA 4X enclosures provide weatherproof protection; consider where the panel will be installed and potential exposure to moisture or dust.
- Control features: Look for run/mute/test switches, external alarms, float controls, and the presence of a terminal block for wiring ease.
- Safety and compliance: UL listings or other certifications add confidence in electrical safety and reliability.
- Additional capabilities: High water alarms, multiple floats, or separate pump/alarm circuits can be decisive for flood-prone locations.
- Installation considerations: Some panels require more complex wiring or external components; ensure compatibility with your existing sump or pump system.
Frequently Asked Questions
- What is a simplex pump control panel? — It is a single-pump control assembly that manages a pump’s operation, typically including a contactor, a switch, and wiring terminals.
- When should I choose a weatherproof (NEMA 4X) model? — Use it for outdoor or damp environments where protection against moisture is necessary.
- Do I need a high-water alarm on my panel? — If flood risk exists or audible/visual alerts are important, a panel with a built-in alarm is beneficial.
- What does UL-listed mean for a panel? — It indicates a third-party safety assessment and compliance with electrical standards, which can be important for professional installations.
- Can I replace only part of my panel? — Replacement parts vary by model; check compatibility with the original enclosure and control components.
- Is a three-float panel necessary? — Three floats provide enhanced level sensing for complex basins; use if multiple sensing points are needed.
