Immersion Pumps
(S)TC260...460

Closed impellers

Immersion Pumps
The immersed parts of types (S)TC260 to (S)TC460 are made of stainless steel. They are designed for use on central coolant systems and CNC machining centers with internally cooled tools.

Extended length is possible. See medium pressure pumps features within the technical information section.
