ST1 / ST1F

ST1 / ST1F

3/4 Inch Discharge, .25 HP, 115V, 27 GPM, 23 ft. Total Head

The ST1 Series Submersible Pumps provide a rugged, compact design option when the applications call for value as well as trusted performance. The pumps are an ideal choice for common household moving water applications such as: flooded rooms, flat roofs, fill tanks, basins, fountains and waterfalls. The aluminum pump casing resists corrosion and supports the dissipation of internal heat.

The ST1 and ST1F are designed with powerful capacitor assisted electric motors, internal thermal overload protection, dual shaft seals, and a positive direct drive thermoplastic impeller secured with stainless steel fittings.

All power cords provide strain relief, and the model ST1F is engineered with an internally adapted mechanical float switch to automatically regulate the operation of the pump
