Vertical centrifugal pumps overview
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 200 mm to 500 mm; in addition, by installing an intermediate bearing, immersion depths up to 2.500 mm are possible. The equipment with customer-specific installation flanges is possible, if desired.
OPTION: If required, Series RT vertical centrifugal immersion pumps can also be fitted with an integrated variable-speed drive.
In all RENNER centrifugal pumps, the pump, motor and frequency converter form one compact unit. This allows small dimensions, increases operational readiness and reduces costs.
The advantages of the variable-speed drive integrated in the motor:
The frequency converters are available in various versions. Control is optionally possible via:

Choice of material
Metal-free and all-plastic making of our pumps is standard since this design guarantees best protection from corrosion. Housings may be also made of special stainless steel. We offer the right combination of materials for any fluid to be delivered, depending on its temperature.
