Goulds Water Technology introduces the GFK and GFV Series, a range of high-performance submersible sewage pumps for residential, light commercial and industrial wastewater applications. The pump series features Xylem’s unique K-impeller technology, which minimizes downtime, reduces clogging and enhances efficiency when pumping wastewater. Both 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 these series share include: cast iron components for long product life and easy maintenance; durable bearings; double mechanical seals that provide extra protection against the risk of pump damage or failure; and upgraded panel installation options for high temperature and seal leak detection. http://info.xyleminc.com/wastewater-solved-gwt.html
