Little Giant VCMA-20ULS 80 GPH Condensate Pump

The VCMA-20ULS from Little Giant is a compact, vertical-type condensate pump designed to automatically remove condensate from boilers, furnaces, air conditioners, and dehumidifiers. It features a 1/30 HP motor, 93 watts, and a 115-volt supply. The unit is thermally protected and built to last with an ABS tank, stainless steel motor shaft, and a fan-cooled motor. It can handle water temperatures up to 140°F (60°C) and includes an overflow-detection switch option for added safety in sensitive installations.
Little Giant VCMA-15UL 65 GPH Condensate Pump

Featuring a vertical-type switch to minimize footprint, the VCMA-15UL is a 1/50 HP pump designed to automatically remove condensate from HVAC and dehumidification equipment. It is thermally protected and calibrated for 115 volts with a 60 Hz fan-cooled motor. The ABS tank, motor cover, and volute, along with a stainless steel motor shaft, provide durability, and it supports water temperatures up to 140°F (60°C).
Little Giant VCMA-15ULST 65 GPH With Overflow Switch

This model adds an overflow detection switch and includes a longer 20-foot tubing option, ideal for configurations where the drain line is remote. It uses a 1/50 HP, 1.0 Amp, 60-watt motor at 115 volts and 60 Hz, with a fan-cooled design. The pump’s ABS tank and stainless steel shaft support reliable operation and long life, while maintaining protection up to 140°F (60°C).
Diversitech ULTRACP-22 Auto Condensate Pump

Diversitech’s ULTRACP-22 offers a 120V motor suitable for condensate as high as 160°F, with a maximum lift of 22 feet. It is designed for standard HVAC/R condensate removal, providing reliable automatic operation for condensate management. The unit includes a robust pump mechanism and is built to handle typical residential and commercial setups where higher vertical travel is required.
AQUASTRONG HVAC Condensate Pump

The AQUASTRONG condensate pump is a versatile 115V/230V pump with a 1/38 HP motor and an 85 GPH rating. It includes an automatic safety switch design wired to detect high water levels and shut off the system to prevent overflow. The unit features a compact vertical centrifugal design with a removable reservoir, providing straightforward maintenance and a durable, plastic construction for corrosion resistance. It can lift water up to about 20 feet and handle typical condensate loads from air conditioners and furnaces.
DiversiTech CP-22 Series Condensate Pump

The DiversiTech CP-22 Series provides a 120V condensate pump rated for standard HVAC/R applications with a 22-foot lift. It includes tubing options and a removable check valve for flexible installation in tight spaces. This model is designed for reliable condensate removal and compatibility with multiple pieces of equipment in residential and light commercial settings, ensuring dependable performance across typical condensate loads.
Buying Guide: Key Considerations And Comparisons
- Lift height (head): Consider the vertical distance the pump must move condensate. Higher lifts require models like the ULTRACP-22 or CP-22 with longer tubing or tubing options.
- Flow rate (GPH): Choose a pump with sufficient GPH for the condensate load. Larger homes or higher humidity climates may benefit from higher-capacity units (e.g., 65–80 GPH).
- Safety features: Overflow detection switches and high-water alarms help prevent flooding. Thermally protected motors reduce overheating risk.
- Power and efficiency: Most options operate on 115V AC. Look for energy-efficient motors and durable materials (ABS tanks, stainless shafts) for longevity.
- Maintenance and accessibility: Removable tanks, check valves, and tubing compatibility simplify installation and service.
- Compatibility: Ensure the unit is suitable for condensate temperatures (often up to 140°F/60°C) and fits with existing drainage lines and reservoirs.
- Durability: ABS tanks, stainless steel components, and corrosion-resistant plastics extend life in humid environments.
- Installation footprint: Vertical pumps with compact footprints are beneficial for tight spaces near furnaces or air handlers.
In selecting a 120-volt condensate pump, compare lift height, flow rate, safety features, and installation flexibility. For settings with remote drains, models offering longer tubing and overflow protection provide added assurance. Durability and warranty considerations are also important, as pumps operate continuously in humid spaces.
