Goulds GSP0511 Sump Pump 0.5 Hp 115V Cast Iron

Product Description

The GOULDS GSP0511 is a 0.5 horsepower, 115-volt cast iron sump pump designed for residential and light commercial water removal applications. It features a vertical float switch that activates and deactivates the pump automatically based on water level, reducing the need for manual monitoring. Cast iron construction provides durability in demanding wet environments. Licensed plumbers and pump service technicians are the primary installers of this unit. The vertical float switch configuration makes it well suited for standard sump pits where reliable automatic cycling is required.

The GSP0511 is used in residential basement sump pits and crawl space drainage applications where groundwater intrusion must be managed automatically. The vertical float switch design is appropriate for sump basins with enough diameter to allow unrestricted float travel. This pump operates on standard 115-volt single-phase power, making it compatible with typical residential electrical service without the need for dedicated high-voltage circuits or three-phase supply.
