Lip seal Omniseal® 70

circularelastomerrubber

lip seals offer double lip designs that are used in high pressure and speed applications. This sealing solution has an option of having a primary threaded primary lip with a standard secondary sealing lip for lubricated condition. 70 lip seals are designed for pressures up to 400 PSID lubricating media and speeds up to 3,500 ft./min. Maximum PV 300,000 lubricated, 50,500 non-lubricated. 80 lip seals are designed for sealing lubricating media at high speeds 4,500 ft./min. and pressures up to 250 PSID. Maximum PV 200,000 lubricated. They are designed for clockwise shaft rotation viewed from the atmosphere side. 90 lip seals are the same as series 80 except they are designed for a counterclockwise shaft rotation when viewed from the atmosphere side. A good example of where a PTFE lip seal replaces both elastomer and carbon face seals is the air compressor market, which often uses 70 / 80 / 90 lip seals. Omniseal Solutions started working with most major air compressor companies in the mid 1980s, replacing rubber lip and carbon face seals prone to leakage. Original designs were based on conventional high pressure lip seals. Over time the demands increased to zero leakage and extended seal life. New technologies were developed to more than triple the seal life while maintaining tight leakage control. As a result, our polymer lip seals are looked to as the industry standard with the ability to offer over 40,000 hours of maintenance-free service.
