Stackpole Ltd. Pump Components Division was a member of the Sterling Group of companies. Stackpole was originally founded in 1906 to construct dry batteries for Ford, later moving fully into the automotive system fabrication market in 1952. The Pump Compontents division would close its doors in 2006, likely the victim of a the massive automotive industry die-off as a part of the recession that we are just now clawing our way out of.
