single end, multiple springs and PTFE bellow working together to provide compensation, balanced, independent rotary direction. The PTFE bellow can resist strong corrosion. The deflection of resistance can reach to 1.5 mm. This seal component has a compact structure and easy to install. When the medium temperature is above 80 ºC, cooling jacket is needed with water cooling.
