Sier-Bath Rotary Pumps

Sier-Bath Rotary Pumps

Beginning in 1945, Sier-Bath gear pumps were introduced to the industrial world.  For 32 years Sier-Bath pumps were a staple in the energy business, and in 1977 were acquired by Worthington pumps.  Through a series of mergers and acquisitions with Dresser and Ingersol-Rand, and eventually Flowserve in 2000, the Sier-Bath products are now part of the Flowserve family.
