What we make, and what we don't

We design and build pumps, valves, strainers and the controls that run them. We do not make compressors, blowers or the pipe between them.

Narrow range, deep inventory: that is the trade we chose, and it is why a plant can call us about a pump we sold in 1989 and get a part.

Halvorsen pumps and valves on the assembly floor

From a repair bench to 31 countries

The short version of sixty-four years on West Canal Street.

  1. 1962

    A repair shop for the breweries

    Erik Halvorsen opens a two-man pump repair shop serving Milwaukee's breweries.

  2. 1968

    The first Halvorsen pump

    The HC end-suction pump ships, designed around the failures the shop kept repairing. It is still in the catalog.

  3. 1979

    Valves and strainers join the range

    Customers ask for the parts on either side of the pump. Ball valves and Y-strainers follow, sharing materials and spares.

  4. 1994

    Second generation, first exports

    Karin Halvorsen takes over from her father. The first orders ship to Canada and Mexico.

  5. 2008

    Houston service centre

    A second site opens to serve Gulf Coast chemical and midstream customers with 48-hour response.

  6. 2019

    Third generation, controls in-house

    Anders Halvorsen becomes president. A UL 508A panel shop is added so pump packages leave as one tested unit.

  7. 2026

    Test capacity doubles

    A 14,000 sq ft addition brings a 10,000 gpm loop and witnessed-test bays for customer acceptance.

Made here

Castings come from foundries in Wisconsin and Indiana. Machining, assembly, hydrostatic and performance testing happen under one roof on West Canal Street.

Every pump leaves with a test certificate signed by the technician who ran it.
