HVAC Condensate Pump for 277V Systems

The Hartell A3X-277 is a plenum-rated condensate removal pump built for heating, ventilation and air-conditioning installations that operate on 277V AC power. It handles discharge and intake through barbed connections and includes motor thermal protection for reliable operation in commercial or residential HVAC equipment.

30-Foot Maximum Head Determines Fit

The single specification that decides suitability is the maximum head of 30 feet, which defines the vertical lift this pump can achieve. Flow rates fall from 6.43 gpm at 1 foot of head to 5.4 gpm at 10 feet, 4.67 gpm at 15 feet and 3.83 gpm at 20 feet, so the system’s actual lift must stay within this curve.

Rated for 212 °F Media Temperature

In normal use the pump is designed for media temperatures up to 212 degrees Fahrenheit, reflecting its plenum-rated construction for demanding HVAC environments. The 1/2 hp motor runs on 277V AC with integrated thermal protection, limiting power draw and noise while maintaining consistent condensate removal.
