Features： For plain shafts Single and dual seal Elastomer bellows rotating Unbalanced Independent of direction of rotation No torsion on bellows
Advantages： Shaft protection over entire seal length Protection of seal face during installation due to special bellows design Insensitive to shaft deflections due to large axial movement ability Universal application opportunities Suitable for low-end sterile applications Important material certifications available High flexibility due to wide provision of materials
Recommended applications： Process industry Chemical industry Pulp and paper industry Water and waste water technology Food and beverage industry Sugar industry Water, waste water, slurries (up to 5 % by weight) Pulp (up to 4 % otro) Latex Dairies, beverages Sulfide slurries Chemicals Oils Chemical standard pumps Helical screw pumps Stock pumps Circulating pumps Submersible pumps Water and waste water pumps Oil applications
Background Knowledge: Allowable value of shaft radial play: Excessive shaft radial play will cause the jittering or deviation of the shaft,thus increase the seal contact surface, reduce lubricating film, and accelerate wear, which is detrimental to the sealing performance and service life of the mechanical seal. Therefore, JB4 127-85 stipulates：
Allowable value of radial play of shaft（or sleeve）where mechanical seal is installed
Outdiameter of shaft（or sleeve）（mm）
value of radial play
10-50
0.04
50-120
0.06
shaft radial play is not only related to shaft diameter, but also related to shaft speed of the mechanical seal.
