Welcome to Arms Pumps

In the 1920's my Great Grandfather (Fritz "Fred" Stadelhofer) began making centrifugal water pumps in his back garage on California Street in Berkeley, CA. Eventually it would be known as BERKELEY PUMPS. My Grandfater and my Father were machinist and draftsmen for 40 years at Berkeley Pumps. The Berkeley Pump Company sold to Transamerica in 1984. In 1987, keeping most of the original employees, ARMS PUMPS was started.

We now have over 100 years of combined employee experience. My father made his own product line of End Suction Centrifugal water pumps. Our pumps are made from the highest quality materials, and have been tested up to 87% efficient. Recently, STA-RITE bought the Berkeley Pump Company and many of their products are being made in Mexico and other parts of the world, except within the United States.

We proudly manufacture and assemble our water pumps here in America. Our pumps contain 25% more cast iron that most other manufacturers use. We also repair most major centrifigual pumps. We stock most replacement parts for most pump brands to allow for fast turn around service. We are old Berkeley Pumps and many of the Berkeley pumps are completely interchangeable with our own.

I am more than happy to answer any questions you have. You can also visit You Tube to view a demonstration of our Jet Primer in action.
