PTFE lips rotary shaft seals Liangziptfe's QuanSeal™ PTFE lips seal was introduced in the early 1998's. The seals were designed to bridge the gap between conventional elastomer lip seals and mechanical face seals. Hostile environments such as extreme temperatures, aggressive media, high surface speeds, high pressures, and lack of lubrication forced the designer to specify the expensive and complicated mechanical face type seals. QuanSeal™ PTFE lips seal provides the designer a significant improvement in performance over elastomer lip seals at a much lower cost than the mechanical face seal. QuanSeal™ PTFE lip seals solve difficult applications which are not addressed by conventional elastomer seals. We exceed the performance of elastomer lip seals in the following areas: 1.Lower friction Generates less torque - Less heat - Requires less power Typical Applications: Conveyor Rollers, electric motors, rolling stock, generators, compressors, vacuum pumps, high performance vehicles 2.AGGRESSIVE MEDIA RESISTANCE Unaffected by solvents, chemicals, acids, synthetic & adulterated oilsTypical applications: Chemical processing equipment, pumps, mixers, agitators, blenders, pharmaceutical & foods. 3.Capable of surface speeds to 35m/s 4.Works to temperature extremes(-100 to+250C) Typical Applications: Aerospace, military, automotive, steel mills, crankshafts, moulding machines 5.Has extended seal life in dry or abrasive media Reduced breakout friction and stictionTypical Applications: Powder sealing, dust/dirt excluders, off road vehicles, radar equipment, paper mills 6.Capable of pressures to 6Mpa
