Description

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.
