PULSCO's founder, Wilhelm Everett, installed the first surge control system in 1922. In the mid 1950's, Pulsation Controls Corporation was founded in Santa Paula, California.


In 1969, the company was sold to American Air Filter and moved the operation to Louisville, Kentucky. Tolo Incorporated purchased the surge control and pulsation dampener product lines in 1982 and moved the company back to Orange County, California.


During the early 1970's PULSCO founder Wilhelm Everett and renowned artist Wendell Dowling developed and illustrated an Analogy for Surge Control of Waterhammer. The analogy makes use of a hapless train engine and a small group of equally ill-fated boxcars to help illustrate the catastrophic events that can occur during startups and shutdowns in an unprotected water piping system.


PULSCO reentered the vent and line silencer market in 1986, with an exclusive marketing arrangement with Fisher Control Corporation.


Advanced Technology Company acquired PULSCO in 1999 and remains as the current parent company. Advanced Technology Company, with capabilities in electron beam welding, manual/automatic TIG welding, laser processing, vacuum furnace brazing and CNC machining, has been manufacturing industrial and aerospace products to PULSCO specifications for a number of years. 


Today, PULSCO is located in Santa Ana, California providing engineered solutions for fluid pulsation, noise, and surge control.
