Welcome to the Viking Pump foundry in Cedar Falls, Iowa, where we’ve been at the forefront of manufacturing gear pumps for decades. Our foundry is a cornerstone of our vertical integration capabilities, allowing us to produce castings and parts at speed.

Flange standards used on Viking pumps have been in place for over a century so EVERYONE should be experts on this now…right? It turns out not so much. There are various standards and various design differences in each standard. AND the standards have evolved over the years, leading some to use obsolete terms which only compounds the confusion. The following should help clear up some of this confusion as well as give you a resource to help answer questions for others.
