Closed impellers
Immersion Pumps
models (S)TC40...(S)TC160 have been especially developed to supply internally cooled tools with coolant.
Closed impellers provide optimal hydraulic efficiencies while minimizing power consumption.
A frequency alternator 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.
Longer pump lengths and threaded inlets are available upon request.
Please see medium pressure pumps features in the Technical Information section of this catalog or call 248-926-9400 for details.
