The Everbilt 1/2 HP Cast Iron Submersible Sump Pump (Model HDS50) delivers industrial-strength flood protection for residential basements and drainage sumps. Featuring a heavy-duty cast iron motor housing and volute for maximum thermal dissipation, energy-efficient PSC motor with automatic thermal protection, and a space-saving vertical magnetic float switch engineered for compact 10-inch or larger basins. Pumps up to 5,100 GPH at 0 ft (3,780 GPH at 10 ft lift) and passes up to 1/2-inch solids.
Heavy Class 30 Cast Iron Body: Rugged cast iron motor housing and volute dissipate heat rapidly, ensuring continuous heavy-storm dewatering without motor overheating. High-Efficiency 5,100 GPH Flow: Moves up to 5,100 GPH at 0 ft and 3,780 GPH at 10 ft vertical lift with 26-foot maximum shut-off head.
Space-Saving Vertical Float Switch: Vertical switch mechanism operates without snagging on pit walls or discharge pipes; fits in basins 10" or larger. 1/2-Inch Solids-Handling Vortex Impeller: Heavy cast iron vortex impeller passes 1/2-inch debris and silt without binding or loss of hydraulic pressure.
Epoxy Powder-Coated Corrosion Shield: Double-coat epoxy protects against aggressive groundwater, corrosive minerals, and rust for years of continuous submerged duty.

Contact usYes. Drill a 3/16-inch weep (relief) hole in the discharge PVC pipe, approximately 1 to 2 inches above the pump discharge outlet and below the check valve, angled downward to prevent airlocks.
The vortex impeller is designed to pass solids and debris up to 1/2-inch in diameter without clogging, making it much more durable than standard thermoplastic utility pumps.
Because it utilizes a space-saving vertical float switch rather than a tethered float, it operates reliably in compact sump pits down to 10 inches in diameter.
Because of the heavy cast iron body and water immersion, motor hum and vibration are almost entirely silenced. You will typically only hear the quiet click of the check valve.
Yes. The oil-filled cast iron motor housing quickly transfers motor heat to the surrounding sump water, allowing it to cycle continuously through extended severe rainfall events.
