PRESSURE UP TO 10/15/150 BAR
Function and Working Principle of VR Lip Seal
The operational concept of this springless VR radial shaft seal hinges on the utilization of rubber-elastic sleeve bodies, properly tensioned over supporting elements made from stainless steel or other metals. The sealing lip, which is inclined and interfaces with the sleeve body, adjusts its orientation—either inward or outward—depending on the installation configuration and the directional pressure of the sealed medium.
The sealing action is facilitated by the radial and tangential tension exerted on the sleeve body. This tension imparts a spring-like characteristic to the sleeve, ensuring optimal contact between the sealing lip and the rotating shaft. Consequently, the seal effectively mitigates shear stresses induced by rotational motion and adeptly absorbs vibrations and deviations in concentricity, enhancing its operational stability.
Furthermore, the seal's construction minimizes the risk of the sealing lip partially lifting during shaft rotation, thereby mitigating any potential pumping effects. This meticulous design approach ensures the seal's reliability and longevity in demanding applications.
Advantages of VR Lip Seal
High-pressure applications (10 Bar/15 Bar/ 150 Bar)
Highly suitable for compact space application
No damage to the shaft
Very little scoring due to the springless feature
Very little power loss due to less friction on the shaft surface
Suitable in food, medical and critical sealing application
Applications of VR Lip Seal
All applications where standard oil seal fails to withstand high pressure and also for compact spaces where standard oil seals are difficult to install.
General mechanical engineering (e.g. spindle seals)
Electrical engineering (e.g. motors, rotary encoders)
Medical technology (e.g. very small seals for pumps and instruments)
Pump construction / fan construction (e.g. submersible pumps, centrifugal pumps, axial fans)
Compressor construction (e.g. screw compressors)
Automotive (e.g. climate compressors)
Food machines (e.g. kneading machines)
Agitator and blender and liquidizer technology (e.g. bowl cutter, milk powder machines)
Household machines (e.g. blender, lye pumps, washing machines)
Shipbuilding (e.g. ship shafts)
Gear construction (e.g. high-speed transmission gearing, spur gears)
General vehicle building (e.g. water pump seal, gearbox seal)
Rotary union (e.g. pneumatic controls)
