Immersion Pumps (S)TC25

Immersion Pumps
Our multistage pump models (S)TC25...(S)TC460 have been especially developed to supply internally cooled tools with coolant fluid.
Closed impellers provide optimal hydraulic efficiencies while minimizing power consumption.
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 length is possible. See medium pressure pumps features within the technical information section.
