Flint and Walling was established in 1866 making it one of the oldest pump companies in the United States. With the growth of electricity to rural areas in the early 1900s, the company placed more emphasis on designing electric powered equipment. By the early 1930s Flint and Walling had pioneered a line of convertible jet pumps which earned them a reputation of product leadership in water well pumps.

Flint and Walling's 6" submersibles carry on with the pioneering tradition. The 6P series is a high capacity 6" submersible for commercial, municipal, industrial and agricultural applications. Any water well requiring a high capacity output and having a 6" or larger casing, can be matched to one of F&W's quality submersibles. If you need more than 
120 GPM, The 6T series of 6" Turbine submersibles will fill the bill.
