Little Giant VCMA-15ULST 115 Volt Condensate Pump

The Little Giant VCMA-15ULST operates at 115 volts with an 80 GPH capacity and an overflow detection switch, paired with a 20-foot tubing option. It features a vertical-type switch to minimize footprint and a thermally protected, fan-cooled motor rated at 1/30 HP. The unit uses an ABS tank and motor cover, a stainless steel motor shaft, and a motor protected against thermal overload, suitable for condensate from boilers, furnaces, ACs, and dehumidifiers up to 140°F (60°C).

Little Giant VCMA-15UL 115V Condensate Pump (No Safety Switch)

This version delivers 65 GPH at 115V with a 1/50 HP motor and a compact footprint. It maintains robust construction with an ABS tank, stainless steel motor shaft, and thermal overload protection. It is CSA certified for US and Canadian standards, designed to automatically remove condensate from HVAC and dehumidifier systems, and suitable for temperatures up to 140°F (60°C).

Little Giant VCMA-20ULS 115V Condensate Pump

With 80 GPH and a 1/30 HP motor, the VCMA-20ULS offers a slightly higher flow and a compact form with a 6-foot power cord. The pump is designed to automatically remove condensate from HVAC and refrigeration equipment, featuring a thermally protected motor and a stainless steel shaft. It is CSA certified and built to withstand condensate temperatures up to 140°F (60°C).

Little Giant VCMA-20ULST 115V Condensate Pump

The VCMA-20ULST adds an overflow detection switch and 20-foot tubing, maintaining the 1/30 HP, 80 GPH performance. It uses a vertical switch to minimize footprint and offers a robust ABS body with a stainless steel shaft. Built for reliability in HVAC, refrigeration, and dehumidification applications, it remains within 140°F (60°C) condensate tolerance.

Diversitech ULTRACP-22 Ultra Series Condensate Pump

The Diversitech ULTRACP-22 is a 120V condensate pump with a maximum lift of 22 feet. It is designed for standard HVAC/R condensate management and includes a removable check valve for versatile installations. The high-performance motor is rated for condensate temperatures up to 160°F, making it suitable for a wide range of systems.

Aquastong and Related Models (Context for 115V Pumps)

While the Aquastrong models listed here span 115V and 230V variants, they illustrate the broader category of automatic condensate removal pumps designed for HVAC systems. Key differences to consider include maximum GPH, lift height, safety switches, tubing length, and durability features such as thermally protected motors and corrosion-resistant housings.

Buying Guide

When selecting a 115V condensate pump, consider these factors:

• Flow rate and lift: Match GPH and vertical lift to your system’s condensate volume and the distance to drainage.
• Overflow and safety features: Switch-based overflow detection prevents tank overfill; a built-in safety switch can shut off connected equipment in high-water conditions.
• Cord length and tubing: Longer cord and tubing options (6 ft to 20 ft) simplify installations and routing.
• Motor protection: Thermally protected, fan-cooled motors increase longevity in humid environments.
• Materials and build: ABS tank and stainless steel shaft offer durability; consider temperature tolerance up to 140°F (60°C) or higher if your condensate is warm.
• CSA/UL certification: Certifications ensure compliance with US and Canadian standards.
• Maintenance and service life: Look for units with removable tanks or easy-access components for cleaning and inspection.
• Installation footprint: Vertical switch designs help minimize space in tight installations.

For most residential and light commercial HVAC setups, pumps with 65–80 GPH capacity and optional overflow switches provide a balance of reliability and ease of use. If your system requires longer tubing or higher lifts, select models offering 20 ft tubing or lifts up to 22 ft, such as the 20ULST and ULTRACP-22 variants.
