Vertical centrifugal immersion pumps RT

These pumps without sealings and safe-to-run-dry, out of fully plastic material, are expecially space-saving and are installed mainly in industrial facilities.

The pumps are equipped with special seals, which prevent, also with heavily creeping solutions, the escape of steam and so the hereby created undesired crystallization.

As standard the pumps are equipped for immersion depths from 200mm to 500mm; in addition, by installing an intermediate bearing, immersion depths up to 2.500mm are possible. The equipment with customer-specific installation flanges is possible, if desired.
