Closed impellers

Immersion Pumps

series TH and FH use closed impellers in order to minimize power consumption and to optimize hydraulic pump efficiencies.

In addition, the TH series offers high pressures at short immersion depths.
Inline pumps of the series FH can be used as
boosting pumps if provided with positive inlet pressure. This inlet pressure can be provided by the central coolant supply or a feed pump. In such a setup, pumps of the series FH can raise the incoming pressure by up to 375 PSI (26 bar).

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.
