The story of Cornell starts in 1946 when 5 people working at Pacific Pump Company decided to head out on their own. Having a complete service department, they became familiar with what most of the common pump failures were. Many motor failures came from pressure spikes during operation, overloading capacity and water related failures of the pump end motor bearings. With many parts in stock and facilities to fabricate the rest, Cornell would service any model of pump.
