Immersion Pumps STH28

Immersion Pumps
series STH use closed impellers in order to minimize power consumption and to optimize hydraulic pump efficiencies.
The STH series offers high pressures at short immersion depths. A frequency converter can be supplied for special applications or for matching the pump characteristic to a specific duty point. See page "Control/Regulation" in the Technical Information section of this catalog for further information.

Extended lengths are available. See medium pressure pumps features within the technical information section.
