Welcome to Arms Pumps

We have owned and operated ARMS PUMPS as a family business here in Tracy, CA since 2012.  We have over 100 years of combined employee experience. 

In his back garage on California Street in Berkeley, CA, Fred Stadelhofer (my Great Grandfather), began making centrifugal water pumps in the 1920’s.  He would eventually become the founder of Berkeley Pumps, located on 4th Street in Berkeley, CA.  My Grandfather Fritz and Father Eugene followed in his footsteps and were machinists and draftsmen for Berkeley Pumps for 40 years.  The Berkeley Pump Company changed ownership in 1984.  However, in 1987, ARMS PUMPS was founded, retaining many of the original employees from Berkeley Pumps.

We proudly manufacture and assemble our water pumps here in America. Other pump companies have many of their products being made in other parts of the world, while we proudly continue to manufacture everything here in Tracy, CA. Our pumps contain 25% more cast iron than most other manufacturers use; it makes our pumps more robust, hardy and longer lasting. Our pumps are made from the highest quality materials, and have been tested up to 87% efficient. My father made his own product line of End Suction Centrifugal water pumps based on a lifetime of experience constructing water pumps, which we continue to produce. Many of the old and new Berkeley Pumps are interchangeable with our own, so we can repair most major centrifugal pumps. We also stock replacement parts for a wide variety of pump brands to allow for fast turn-around service.

We are more than happy to answer any questions you have. We believe it is important for our customers to be able to talk to someone where their pump is built.

Ken Stadelhofer (President)
