Little Giant VCMA-20ULS Condensate Pump
The Little Giant VCMA-20ULS is a 115-volt automatic condensate removal pump designed to handle condensate from boilers, furnaces, air conditioners, and dehumidifiers. It features a vertical-type switch to minimize footprint and a thermally protected 1/30 HP motor, rated at 93 watts and 1.5 amps. The unit is built with an ABS tank and motor cover, a stainless steel motor shaft, and a fan-cooled design. It can tolerate water temperatures up to 140° F (60° C) and includes a 6-foot power cord for flexible installation. The integrated overflow detection switch helps prevent unexpected overflow in tight spaces.
Little Giant VCMA-15UL Condensate Pump
The VCMA-15UL operates at 115 volts with a 1/50 HP motor and a 60-watt rating. It provides 65 GPH pumping capacity and uses a vertical switch to minimize space. The pump includes a thermally protected motor and a durable ABS tank with a stainless steel shaft. Suitable for condensate produced by HVAC and dehumidification equipment, it shares the same CSA-listed safety standards and temperature tolerance as larger Little Giant models, making it a compact alternative where space is at a premium.
Diversitech ULTRACP-22 Ultra Series Pump
The Diversitech ULTRACP-22 is a 120V condensate pump designed for HVAC/R equipment, featuring a maximum lift of 22 feet. It focuses on reliable condensate evacuation and is rated for condensate temperatures up to 160° F, supporting standard condensate management needs in larger or more demanding systems. The pump combines a high-performance motor with a design tuned for steady operation, making it a strong choice for equipment with higher condensate output or taller drain runs.
AQUASTRONG HVAC Condensate Pump
The AQUASTRONG pump supports 115V or 230V operation with a 1/38 HP motor and 85 GPH capacity. It includes an automatic safety switch option to shut off linked HVAC appliances if water levels rise, reducing overflow risk. The unit uses a vertical centrifugal design with a removable reservoir and a five-inlet port configuration for versatile connections. Users benefit from a compact, durable build and straightforward installation, suitable for a range of air conditioning and furnace setups.
DiversiTech CP-22 Series Condensate Pump
The DiversiTech CP-22 Series offers a 120V condensate pump designed for HVAC/R equipment with a 22-foot lift. It ships with a removable check valve and 20 feet of 3/8″ tubing, enhancing flexibility for routing condensate to appropriate drainage. While detailed motor specs are standard for the line, the emphasis is on reliable lift and easy integration into standard condensate removal systems, suitable for residential and light commercial applications.
Little Giant VCMA-15ULT Condensate Pump
The VCMA-15ULT provides a 65 GPH output with a 1/50 HP motor and a 60-watt rating. It features a vertical-type switch for compact installations, a thermally protected motor, and a stainless steel shaft. It is CSA listed for North American standards, aligning with the safety expectations of residential and light commercial HVAC installations. This model is a balanced option when tubing and space constraints are critical considerations.
DiversiTech CP-22 Series Condensate Pump With Tubing
Another DiversiTech CP-22 option highlights robust condensate management with a 22′ lift and included tubing, designed for straightforward integration into standard HVAC/R installations. The pump is built for reliable 120V operation and easy connection to existing drainage lines. The emphasis on lift and tubing compatibility makes it a versatile choice for varied equipment setups, from home AC units to small commercial systems.
Buying Guide: Key Purchase Considerations
- Lift and head height: Ensure the pump can raise condensate to your drainage point; taller lift is required for higher condensate outlets or secondary floors.
- Flow rate (GPH): Match the pump’s capacity to the condensate generation rate of your equipment. Larger units demand higher flow ratings.
- Electrical compatibility: Most units run on 115V; verify voltage, plug type, and available space for wiring or cords.
- Safety features: Overflow switches, thermal protection, and CSA/UL listings help prevent water damage and ensure safe operation.
- Durability and materials: ABS tanks and stainless shafts improve longevity in humid environments.
- Tubing and fittings: Check for compatible tubing sizes and included hardware (check valves, tubing, adapters) to simplify installation.
- Noise and vibration: Look for fan-cooled motors and compact designs if the pump will be installed in living spaces or noise-sensitive areas.
- Maintenance: Removable reservoirs, accessible check valves, and straightforward cleaning reduce downtime and extend service life.
- Usage context: Choose models with safety switches or higher lift if you have risk of overflow in basements, crawl spaces, or crawlouts.
These considerations help compare models across a range of needs—from compact residential systems to more demanding setups requiring higher lifts or overflow protection. When evaluating, align the pump’s specifications with your equipment’s condensate rate, installation space, and drainage routing to optimize reliability and safety.
