A Legacy of Innovation and Precision Engineering
SIHI (originally founded as Siemens Hermann in Germany in 1920) developed one of the world’s first liquid ring vacuum pumps and quickly grew into a global name in industrial fluid handling. The company became known for its reliable pumps engineered to withstand extreme temperatures, corrosive chemicals, and gas-liquid mixtures.
In 2014, SIHI was acquired by Flowserve Corporation, further expanding its global footprint and enhancing its capabilities in engineered flow control solutions. Today, Flowserve SIHI continues to deliver premium pumps used in the most critical applications worldwide—from chemical plants to pharmaceutical labs—built on over 100 years of innovation.
Flowserve SIHI pumps are manufactured under strict ISO quality standards and are trusted across critical applications requiring low NPSH, high vapor pressure handling, gas entrainment resistance, and temperature stability.
