Cartridges & Mechanical Seals

103 WAVE SPRING SEALS CHARACTERISTICS: • Balanced. • System attached to the shaft by allen screws. • Not dependent on the rotation direction. OPERATING LIMITS: d 1 = 14 ÷ 100 mm p= 25 kg/cm ² v= 20 m/s t= -50÷ +220oC ( *) ( * ) The temperature resistance depends on the material of the secondary seals used. The operating limits are defined by the PV factor which is determined for the sealing system characteristics and those of the application. DESCRIPTION: The balanced contact surface design allows the mechanical seal to be used in applications with high pressures without suffering premature wear. Recom- mended for working with sticky fluids and fluids la- den with particles and fibres. Unlike the multispring models, the wave spring model cannot be blocked or obstructed and its open leaf design produces a self- cleaning effect. Standard L9 type fixed stationary part, standardised seal, compliant with EN 12756 (KB). The casing can incorporate a pumping ring to re- duce the temperature between the contact surfaces and facilitate the barrier fluid movement in the case of double mounting (reference LWS10B-F) .
