Materials for friction pairs with the introduction of eSic-Q7 instead of tungsten carbide for Lowara pumps of the e-NSC and e-LNE/T series
For high-temperature working conditions, the existing RMG12 will be replaced by the new eRMG12 with the introduction of eSic-Q7 instead of U3 tungsten carbide. In this case, the mechanical seals will also be 100% interchangeable, and the pump description will change to indicate the new material. This applies only to diameters 22, 28 and 38, while for 48 and 70 a balanced mechanical seal is the preferred solution. The description and article numbers do not change, except for the high-temperature version using the eRMG12 mechanical seal.
The articles and description do not change, except for the high-temperature version with an eRMG12 mechanical seal.
