Dayton 3ACB9 Bronze Utility Pump 1/3 HP 115/230V

Bronze utility pump for light drainage

The Dayton 3ACB9 is a self-priming bronze utility pump rated at 1/3 hp for 115/230 V AC operation. It suits homeowners and maintenance crews who need a compact, corrosion-resistant pump for intermittent water transfer or dewatering tasks. The brass housing and Buna-N impeller handle clean or slightly dirty liquids up to a maximum viscosity of 5,000 SUS.

Flow capacity and head limits

At 10 ft of head the pump delivers up to 9.6 gpm, drawing 7.2 A at 115 V or 3.6 A at 230 V. Maximum shut-off head reaches 50 ft, corresponding to 21.6 psi, while suction lift is limited to 20 ft. These figures cover typical basement, utility-sink or equipment-drain scenarios, but the unit will not sustain flow beyond the 50 ft head ceiling.

Replaces smaller manual or plastic pumps

This model upgrades from hand-operated transfer pumps or low-head plastic units that cannot self-prime or tolerate 5,000 SUS viscosity. The step up is worthwhile when automatic priming, bronze construction and 1/3 hp continuous duty are required. It does not suit applications needing flow above 9.6 gpm at 10 ft head or discharge pressures exceeding 21.6 psi.
