Little Giant VCMA-20ULS 80 GPH With Overflow Switch
The Little Giant VCMA-20ULS is a 115V automatic condensate pump designed to remove condensate from boilers, furnaces, air conditioners, and dehumidifiers. It features a vertical-type switch to minimize footprint, a 1/30 HP motor, and a thermally protected, fan-cooled design. With an ABS tank and stainless steel shaft, this pump is built to withstand water temperatures up to 140°F (60°C) and includes an overflow-detection switch for safety.
Little Giant VCMA-20ULST 20-Foot Tubing, Overflow Switch
This variant provides the same high-performance 1/30 HP motor with an overflow detection switch and adds a 20-foot tubing option for flexible placement. Its heavy-duty ABS tank and stainless steel shaft ensure durability in HVAC and dehumidification setups, with thermal overload protection and compatibility with up to 140°F condensate temperatures.
Little Giant VCMA-20ULST 20-Foot Tubing Option
This model emphasizes a compact vertical design with a safety overflow switch and a standard 20-foot tubing extension. It shares the same 1/30 HP motor, 115V operation, and rugged ABS construction, making it suitable for limited clearance installations while maintaining reliable condensate removal.
Cleartide Condensate HVAC Pump With Safety Switch
This pump operates at 100-240V and delivers up to 135 GPH with a 27-foot lift height. It includes a three-indicator monitoring system for power, operation, and malfunction alerts, plus an overflow safety switch to prevent leaks. The unit uses a water-cooled brushless DC motor for quiet operation and features a removable reservoir for easy maintenance.
AQUASTRONG HVAC Condensate Pump With Safety Switch
Designed for 115V/230V operation, this pump moves up to 85 GPH with a lift height up to 20 feet. It includes a high-level safety switch wired directly to HVAC equipment to shut off power and prevent overflow. The compact vertical design uses a durable thermoplastic body with multiple inlet connections for flexible plumbing options.
AQUASTRONG 70 GPH Condensate Pump With Safety Switch
This model provides reliable condensate removal at up to 70 GPH with a 16-foot lift, featuring a robust safety switch system to guard against overflow. It is well-suited for air conditioners, furnaces, and dehumidifiers, with a compact footprint and simple vertical installation.
MSKOTOAS 132 GPH Condensate Pump With Safety Switch
The MSKOTOAS pump delivers up to 132 GPH with 20 feet of lift and includes a safety switch and built-in alarm. Its ceramic shafts and soft-start motor design improve durability and reduce wear, making it a strong choice for larger HVAC installations or applications requiring higher lift.
Buying Guide
- Safety switch vs. alarm: Choose a model with a dedicated safety switch that shuts off the system on high water levels, or a combined safety switch with an audible/visual alarm for multi-layer protection.
- Lift height and head pressure: Ensure the pump’s maximum head height meets your installation requirements. Higher lift is important for condensate removal from units located above the pump.
- GPH capacity: Select a pump with sufficient flow for your equipment’s condensate production. Consider peak drainage scenarios and potential future expansion.
- Power supply and voltage options: Most units run on 115V; some offer 230V compatibility. Verify electrical compatibility with your setup and local codes.
- Durability and materials: Look for stainless steel shafts, ABS or durable thermoplastic tanks, and motor protections to withstand condensate temperature and humidity.
- Tubing and fittings: Check tubing length options and inlet/outlet sizes. Longer tubing provides flexible placement; ensure check valves are included if needed.
- Maintenance and indicators: Units with status indicators help diagnose malfunctions quickly. Removable reservoirs and accessible components simplify maintenance.
- Certifications: CSA or equivalent certifications indicate compliance with safety and performance standards for North American use.
- Noise level: For occupied spaces, consider models marketed as ultra-quiet or brushless motor designs to minimize disruption.
- Compatibility with HVAC equipment: Ensure the pump is suitable for condensate temperatures typical of boilers, furnaces, dehumidifiers, and air conditioners in your system.
Across these options, buyers should align the pump’s head height, flow rate, safety features, and installation flexibility with their specific HVAC layout. All listed products provide automatic condensate removal with safety or overflow protections, making them suitable for protecting equipment and surrounding areas from condensate-related issues.
