Condensate Pump Little Giant VCMA-20ULST 115V 80 GPH Overflow Switch

Description

Product Overview

The Little Giant VCMA-20ULST is a compact vertical condensate removal pump engineered for continuous operation in HVAC, refrigeration and dehumidifier systems. Constructed from high‑impact ABS plastic, the pump housing resists corrosion and impact while the stainless‑steel motor shaft provides long‑term durability. The fan‑cooled 1/30 HP motor delivers a maximum flow of 80 gph at a 1‑foot lift, scaling down gracefully to 48 gph at a 10‑foot lift. Powered by a standard 115 V, 93‑watt supply, the unit draws only 2 amps, making it energy‑efficient and easy to integrate into existing electrical circuits.

Key design elements include a vertical‑type overflow detection switch that can trigger an alarm or shut down the connected appliance, and a 20‑foot length of 3/8″ I.D. vinyl tubing pre‑installed for immediate installation. The pump features a 3/8″ OD barbed discharge, three inlet drain holes for rapid water intake, and a maximum operating pressure of 8.7 psi. With a compact footprint of 11″ L × 5″ W × 7″ H and a weight of just 5.5 lb, the VCMA‑20ULST fits neatly into tight spaces while delivering reliable performance.

Usage

This pump is ideal for removing condensate generated by boilers, furnaces, air‑conditioners, and dehumidifiers in residential, commercial, and industrial settings. Install the pump near the condensate collection pan; the built‑in overflow switch will monitor water levels and either sound an alarm (if connected to an external alert system) or shut down the equipment to prevent water damage. The 20‑foot tubing allows flexible routing to a drain or sump, reducing the need for additional fittings.

Because the motor is thermally protected, the pump can operate continuously without overheating, making it suitable for high‑humidity environments such as data centers, laboratories, and large‑scale laundry facilities. The pump’s ability to handle water temperatures up to 140 °F (60 °C) ensures reliable operation even when condensate is warmed by nearby equipment.

Installation requires basic wiring knowledge: connect the pump to a 115 V power source, route the tubing to a suitable drain, and configure the overflow switch according to the manufacturer’s wiring diagram. The pump’s low amperage draw means it can be added to existing circuits without overloading breakers.

FAQ

What size of tubing does the pump use?

The pump comes with a 20‑foot length of 3/8″ I.D. vinyl tubing, which is compatible with standard 3/8″ OD barbed fittings.

Can the pump handle hot condensate?

Yes, the pump is rated for water temperatures up to 140 °F (60 °C), making it suitable for applications where condensate may be warmed.

How does the overflow detection switch work?

The vertical‑type switch monitors water level in the pump’s reservoir. When the level exceeds the set point, the switch can either sound an external alarm or shut down the connected appliance to prevent overflow.

Is the pump suitable for continuous operation?

Absolutely. The motor’s thermal overload protection allows the pump to run continuously without overheating, provided it is installed with adequate ventilation.

What warranty does Little Giant provide?

Little Giant offers a one‑year manufacturer warranty covering defects in materials and workmanship, along with access to technical support for installation and troubleshooting.
