What is "worthington-simpson"

Worthington-Simpson was a British pump manufacturer. Many of their pumps were used in municipal waterworks in Great Britain.

The company has its roots in a steam engine workshop founded by Thomas Simpson around 1785. His sons took over the workshop and founded James Simpson & Co., which became Worthington Pump Co. through a merger in 1903, renamed Worthington-Simpson in 1917. It continued as an independent pump manufacturer until 1969, when it became a subsidiary of Studebaker-Worthington. A series of mergers and divestitures followed. The successor company as of 2013, formed through a number of mergers, is Flowserve.
