SONDERMANN presents a totally new type of magnetically coupled centrifugal pump that works without any sleeve bearing. The coefficient of friction of the new 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.

The new pump includes 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. Since the pump does not have a shaft seal, it is hermetically separated and because of this unique design, leakages through worn shaft sealings are definitely ruled out.

The RM-TS series includes pumps from the RM2-TS type with a delivery rate of 110l per minute, 10 mwc and a 90 W motor to the RM5-TS type with a delivery rate of 1,500l per minute, 60m wc and a 15 kW motor. Technical data and dimensioned drawings of RM-TS pumps are identical with those of standard types of RM pumps.

Simple and reliable design: No liquid cooled sleeve bearings. Increased efficiency by using bearings with an extremely small coefficient of friction. Extremely high resistance to chemicals. All present pumps of the RM-type can be adapted, upon request, to this new system to become absolutely safe to run dry. Also for high speed operation.
