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.

Application example:
Vertical centrifugal pump with an integrated variable speed drive (RT + FU)

The advantages of the variable-speed drive integrated in the motor:

  • Energy saving
  • Fluid control to suit your requirements
  • Space-saving drive
  • No power loss in the switch cabinet by the FC
  • Less installation work
  • The pump is delivered ready to connect and pre-programmed
  • No long, cost-intensive, shielded motor cables
  • No separate EMC-filter
  • Gentle pumping of the medium
  • No heating-up of the pumped medium by energy dissipation
  • No external motor circuit breakers thanks to integrated motor protection functions


The frequency converters are available in various versions. Control is optionally possible via:

  • Terminal strip
  • Analog input
  • Serial interface
  • Potentiometer
  • Control panel
  • Field bus (Profibus, etc.)

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.
