RENNER magnetic centrifugal pumps RM-TS 2 “safe-to-run-dry”
Product overview
The safe to run dry pump – a revolutionary innovation in magnetically coupled centrifugal pump technology
The RENNER RM-TS pump is the first magnetically coupled centrifugal pump in the world that is absolutely safe to run dry. With this series we offer you an absolutely safe to run dry, magnetically coupled centrifugal pump, without any ifs and buts.
The new product-line RM–TS include all advantages of our longstanding experience with pumps of the RM type and the additional certainty that they will not be damaged by dry running. All components of the pump head that are in contact with the fluid, are still metal-free, this is to assure optimum chemical resistance against aggressive fluids.
The sophisticated and reliable design convinces in every respect:
- No slide bearing
- No magnetical axial-thrust equalizer required
- No pin-point contact system
- Extremely high resistance to chemicals
- Upon request, the new system can be always retrofitted to present pumps of the RM-type to make them absolutely safte to run dry
- Trouble-free operation of the pump even at high speeds
- Increase in efficiency because of an extremely small coefficient of friction
Its advantage over sleeve bearing systems:
- The coefficient of friction of this type of bearing that has been used for the first time with magnetically coupled centrifugal pumps, is so low that only a minimum of heat is generated. Therefore, the bearing does not require any cooling or liquid lubrication. (Note: This bearing of the RENNER RM-TS pump for which a patent is filed, assures that the temperature rises to a maximum of just 5 °C above the ambient temperature when the pump runs dry.)
