Little Giant VCMA-20UL-PRO Condensate Pump | 115V High-Efficiency HVAC Pump

Product Details

The Little Giant VCMA-20UL-PRO is the next generation of condensate removal, designed for high-efficiency HVAC systems, condensing boilers, and dehumidifiers. This "PRO" series model takes the reliability of the classic VCMA and enhances it with a slimmer footprint for tighter installation spaces and an external test lever for immediate troubleshooting. Built with a high-performance 1/30 HP motor and a vertical centrifugal design, it effectively moves water when gravity drainage is not an option. Its oil-resistant tank and stainless steel motor shaft make it suitable for the acidic condensate produced by modern gas furnaces, ensuring a long service life in demanding environments.

Key Features:

• Slim Footprint: The most compact design in the Little Giant lineup, providing maximum installation flexibility in crowded mechanical rooms.
• External Test/Run Lever: Allows technicians to manually trigger the pump to verify operation without waiting for the tank to fill.
• Quick-Release Discharge: Features a 3/8" O.D. barbed, 1/4-turn locking discharge adapter with a built-in check valve for easy maintenance.
• Acid-Resistant Construction: Equipped with an oil-resistant ABS tank and impeller, specifically rated for high-efficiency furnace condensate.
• Multi-Inlet Flexibility: Includes three 1-1/8" diameter inlet openings (two with removable plugs) to accommodate multiple drainage lines simultaneously.

Specifications:

• Horsepower: 1/30 HP
• Voltage: 115V AC / 60Hz
• Max Flow Rate: 84 GPH @ 1-foot head
• Shut-Off Head: 21 Feet
• Safety Switch: No (For the safety switch model, see VCMA-20ULS-PRO)
• Tank Capacity: 1/2 Gallon
• Max Liquid Temp: 140°F (60°C)
• Weight: 5.5 lbs

Installation & Maintenance Tips:

• Wall Mounting: Use the included galvanized steel "quick install" bracket to secure the pump to a wall or the side of the HVAC unit.
• Vibration Dampening: The pump is equipped with rubber feet; ensure they are seated properly to minimize noise during operation.
• Check Valve Care: Periodically inspect the 3/8" check valve for debris. If the pump runs but doesn't move water, a clogged check valve is the most likely culprit.
• Safety Note: This specific "UL" model does not include an overflow safety switch. If you need the pump to automatically shut down your AC in case of a failure, ensure you have the "ULS" version or install an external switch.

Common Uses/Applications:

• High-Efficiency Furnaces: Safely removes acidic wastewater from condensing gas units.
• Air Conditioning: Collects and pumps away evaporator coil condensate in basements or closets.
• Dehumidifiers: Provides continuous drainage for large-capacity dehumidifiers in crawl spaces or gyms.
• Refrigeration: Ideal for commercial reach-in coolers and display cases.

Common Questions:

Q: What is the difference between the PRO and the standard VCMA?

A: The PRO series features a narrower tank design for tight spaces, an external test lever, and an improved quick-release check valve system.

Q: Does this pump include the 20 feet of vinyl tubing?

A: The base VCMA-20UL-PRO (554620) typically does not include tubing. Check for "T" models (e.g., VCMA-20UL-T-PRO) if you require pre-packaged tubing.

Q: Can this pump handle hot water from a boiler?

A: It is rated for water temperatures up to 140°F, which is sufficient for most condensing boiler condensate, but not for steam or high-temp boiler blow-off.

The Little Giant VCMA-20UL-PRO combines a space-saving design with professional-grade power, making it the top choice for modern HVAC condensate management.
