WS-SEALS Double Lips Seal Stainless Steel Oil Seals in Telescopic Cylinder Mud Pump Oilfield Stainless Steel Oil Seals

Structural characteristics

The PTFE shell oil seal has unique structural characteristics. The external iron shell skeleton is sturdy and durable, providing stable support and protection for the oil seal, ensuring that it can maintain good shape and installation position in various working environments. The inner PTFE lip is specially processed into a trumpet shape, which has memory shrinkage ability after drawing. When working, the heat generated by friction will tightly hold the lip on the shaft, achieving excellent sealing effect. Moreover, the oil seal does not require additional spring assistance, is insensitive to shaft eccentricity, and can adapt to certain radial runout.

Performance characteristics

It has high chemical stability and can resist almost all chemical substances. Strong acids, bases, oxidants, and organic solvents have no effect on it. The cracking temperature is above 400 ℃, and it can work normally within the range of -200 ℃ to 350 ℃. The friction coefficient of PTFE material is extremely low, only 0.02, which is 1/40 of rubber, so it has outstanding self-lubricating properties. Almost all viscous substances cannot adhere to its surface, which makes the friction loss of the oil seal small during operation, reduces the wear on the shaft, and also reduces the energy consumption of mechanical equipment.

Application

The air compressor industry includes screw air compressors, piston air compressors, etc., which can ensure good sealing performance under high pressure, high temperature, and high speed working conditions. Pump equipment: centrifugal pumps, gear pumps, plunger pumps, etc., can prevent liquid leakage inside the pump and ensure the normal operation of the pump, especially for pumps that transport corrosive or high-temperature media. Automotive industry: can be used for sealing parts such as engines, transmissions, and wheel hubs in automobiles. It is also applied in industries with high sealing requirements, such as food machinery, pharmaceutical machinery, aerospace, etc.
