General Pump (GP) was founded in 1982 by Michael Christopherson, and introduced high quality, high pressure, positive displacement plunger pumps to the U.S. marketplace. GP primarily serves the pressure cleaning industry, and has expanded to serve Vehicle Wash; Drain Cleaning, Sewer Cleaning; Reverse Osmosis; and miscellaneous Industrial Applications.
In 1998, InterPump S.p.A., located in S. Ilario (Reggio Emilia) Italy, acquired GP Companies, Inc. (d.b.a. General Pump, Noramco and GP/Delavan AgSpray Products).
