The wave spring is protected from the fluid. Ideal for using in cleaning progress since the possibility of particles adhering to the seal is considerably reduced. Internally balanced with no need for a stepped shaft (TWS10B). Suitable for working in applications with high pressures. The O-ring resting on the shaft does not cause wear as there is no axial movement (changes in pressure). Seal compliant with standard EN 12756 (KU).
