Wayne Water Systems SPF50 Submersible Sump Pump 1/2 Hp

Product Description

The WAYNE WATER SYSTEMS SPF50 is a 1/2 HP submersible sump pump designed for residential sump pit applications. Running on 115 volts, it uses an automatic float switch with a 2-pole, positive On/Off action that starts and stops the pump without manual intervention. The motor is oil-encased for quiet, cool operation and permanent lubrication. A watertight shaft seal with ceramic, liquid-lubricated construction prevents water from entering the motor housing, and automatic overload protection guards against damage to motor windings. Licensed plumbers and HVAC service technicians are the typical installers for this class of equipment.

The SPF50 fits sump pits as small as 12 inches in diameter, making it suitable for tight residential basement installations. It pulls water through a top-mounted suction strainer, eliminating the need for additional intake protection. The 1-1/2 inch discharge port connects to standard sump discharge piping. The 8-foot power cord is waterproof, 3-prong grounding type, UL listed, and CSA approved. Disconnecting conductors built into the design help protect against lightning damage during storm events when sump pumps are most actively running.
