A submersible wastewater pump to handle 3" diameter spherical solids
October 4, 2010

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 breed 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.

Recognizing that need -- and seeing a gap in the market for a submersible wastewater pump to safely handle a 3" spherical solid -- Gorman-Rupp is today introducing the Infinity SF series of submersible solids-handling pumps. This is the production the company has been promoting under the "Blue Octo" campaign -- and for good reason: The motor portion of the pump assembly is in fact shaped like an octagon. This unique design not only looks different, it performs differently as well. One advantage is that the Infinity series can be operated as a dry-pit submersible pump without a cooling jacket. 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. The Infinity series submersible pump, by entirely doing away with the cooling jacket, similarly does away entirely with those problems.

And as they say in the television commercials: Wait! There's more! Like Gorman-Rupp's self-priming pumps, the Infinity 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.

These new pumps are on display at Gorman-Rupp's booth at WEFTEC 2010 in New Orleans, today through Wednesday, and they will be available for application design immediately. Please feel free to contact us with your questions.
