Submersible pumps made by America's most reliable pump company

Gorman-Rupp is rightly known throughout Iowa and Nebraska (and all over the world) for self-priming pumps -- as rightly they should be, having not only invented the category in the 20th Century, but also having developed it into a true powerhouse modern design in the 21st.

But for as much as we'd like all pumping applications to be appropriate for a suction-lift pump (making it possible to handle all pump maintenance and operation safely above-ground in the fresh air), there are plenty of applications where a self-priming pump unfortunately can't be made to fit. Where those conditions prevail, you need a pump you can depend upon.

Passes 3" solids. Period.

Recognizing that need -- and seeing a gap in the market for a submersible wastewater pump to safely handle a 3" spherical solid -- Gorman-Rupp introduced the SF Series of submersible solids-handling pumps. No gimmicks, no tricks, no roundabout ways of trying to get you to round up to 3". Just 3" solids passage, period. For well over a decade, Gorman-Rupp has been refining and expanding this line of premium submersible pumps to offer reliable service, even in the face of today's challenges in municipal wastewater applications.

Lots of range for your needs

There's lots of range available for your application needs:

Discharge sizes

3" to 8"


75 gpm to 3400 gpm


5' to over 160'

A wet-pit design to handle the worst

In wet-pit applications, SF Series pumps have important strengths. Most models are available with FM approval, and all feature NEMA Premium-Efficiency motors. The vortex models feature excellent efficiencies, and the channel-style models incorporate an external clearance adjustment system to make quick work of maintaining optimal performance.

A unique design with unique dry-pit advantages

SF series submersible pumps from Gorman-Rupp The motor portion of the pump assembly bears a unique octagonal shape. This unique design not only looks different, it performs differently as well. One advantage is that certain members of the SF series can be operated as dry-pit submersible pumps without the need for cooling jackets. The cooling jackets used on many other dry-pit submersibles circulate the liquid being pumped around the motor in order to provide a cooling effect. That cooling effect, however, both reduces the pump's efficiency and introduces lots of dirty liquid to the region surrounding the motor. That problem is gone with the SF Series.

Made in the USA

Like Gorman-Rupp's self-priming pumps, SF Series submersible pumps are designed and manufactured in Mansfield, Ohio. These are "Made in the USA" pumps, qualified for projects requiring American-made products -- and proof positive that high-technology manufacturing is still alive and well in the United States of America.
