When it comes to moving wastewater, pumping contractors want pumps designed to withstand tough environments, perform dependably and operate efficiently. With those performance criteria in mind, Goulds Water Technology, a Xylem brand, recently launched the GFK and GFV series — a range of submersible sewage pumps for residential wastewater applications. The GFK submersible pump features Xylem’s K-impeller technology, designed to minimize downtime, reduce clogging and enhance efficiency when pumping wastewater.

Both the GFK and GFV series are available in multiple sizes and have an air-filled motor with built-in thermal overload protection, enabling the pump to run continuously without overheating. Other benefits that the GFK and GFV series share include cast iron components for long product life and easy maintenance, durable bearings, double mechanical seals that protect against pump damage or failure, and upgraded panel installation options for high-temperature and seal-leak detection.

“Our Goulds Water Technology GFK and GFV pumps were developed with the durability to withstand tough environments while efficiently maintaining dependable performance,” says Bo Gell, Americas product manager, Wastewater, Xylem. “Both are based on proven technology used in our portfolio of robust water utility products.”

Each product line has features designed to fit a variety of residential wastewater applications. Benefits of the GFK Series include a self-cleaning impeller and grinder-handling performance that reduces clogging, according to Gell. It’s also more efficient than traditional submersible sewage pumps, keeping energy costs down, he says. The GFV Series with its vortex impeller can handle the most challenging materials like stringy matter and solids up to 2 1/2 inches in size, resisting clogging, according to the company.

“Advancing wastewater pump technology is critical in today’s complex wastewater industry,” Gell says. “Just as important are pump design options that can fit the specific requirements of each installation. The GFK and GFV series were developed with both aspects in mind.”

GFK and GFV series pumps come in 2- and 3-inch discharge sizes, covering wastewater applications requiring up to 157 feet TDH, 560 gpm and 11 hp. 866-325-4210; www.goulds.com.
