PTFE Lips Rotary Shaft Seals   Product Description QuanSeaL® PTFE lips seal was introduced in the early 2000'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 oils Typical 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 7. For food or pharmaceutical industry PTFE LIPS ROTARY SHAFT SEALS PROFILE QuanSeaL®Metal case PTFE LIPS Rotary SEALS QuanSeaL®MPRS seals DL   Formed Primary Lip with Excluder Lip  Ideal to keep oil and water & dirt out.   SL  Formed Primary Lip   General purpose rotary shaft seal.       TRIL             Dual Primary Lips with  Excluder Lip    Redundant sealing for aircraft or other low leakage systems.

Standard materials cover a great application range. This special compounds have proven themselves exceptionally well in years of use for radial lip seals. Lip materials:  Approximately 45 lip materials are available for special applications.   1. Sealing lips Material Selection: LP1001 Premium grade virgin PTFE for static, slow-dynamic or light-duty application. Also for food-contact service requiring FDA approval. Color:white LP2030 Highly wear resistant in fast-rotary service and on hardened shafts in well-lubricated rotary service, Color:Dark grey LP5010 Highly wear resistant in fast-rotary service and on hardened shafts in well-lubricated rotary service, Color:Dark grey LP8030 Good wear resistant in fast-rotary applications. Less abrasive to soft shaft and in poorly-lubricated service. LP3020 Low coeffication of friction and excellent wear resistance combined with low surface pressure.
