internal combustion engines oil seals

1.Introduction of single lip Pump oil seal

1)Material:stainless steel + PTFE
2)Tyoe: single lip, incongruous double lips,synthetic double lips, three lips and no lip. It is a PTFE stainless steel packaging machines oil seal, we can produce according to customer's design.

2.Characteristic

1)Low friction,power saving.

2)It can replace the traditional oil seals and can be applied in condition of lubrication shortage,high speed,high temperature,strong corrosive medium.

3.Application Range

1)Speed: 40m/s

2)Pressure: 2Mpa

3)Temperature: -60°C

4)Medium:oil,bio oil,water,air and others.

5)Use: Engine ,Hydraulic pumps, vacuum pumps, mixers, actuators, robotics, compressors, pharma equipment, chemical pumps, loading arms, rotating couplings, packaging machines.

4.Material information

1)PTFE(Polytetrafluoroethylene): Display almost universal chemical resistance, an extremely low friction value which results in very good sliding characteristic, no stick-slip effect, particular rigidity and almost unlimited ozone, weathering and ageing resistance, PTFE is impervious to almost all known hydraulic media, lubricants, chemicals and solvents.PTFE is non-flammable and so does not constitute and additional hazard in case of fire. Pure PTFE is not totally without disadvantages as it has a tendency to cold flow or crawl under pressure load. These weaknesses are counteracted by the use of seal compounds mixed with fillers.

Temperature:-55~+260°C

2)PTFE types:

Carbon-graphite filled, Ekonol filled, Rulon®, Glass/MOS2 filled, Fluoroloy 72 (FDA), Gylon white (FDA), Gylon-graphite, other types on request.

3)Stainless steel:Carbon steel, aluminium, SS 304, 316, 316Ti.

PTFE lipseals are often the ideal solution for critical applications. We can engineer the desired solution for you.
