Mechanical Seals PPT
Mechanical Seals
Mechanical Seals. features: *Invisible leakage*Less friction/power loss*No to little wear on the shafts or sleeves*Flexibility - to accommodate shaft deflections and "End Play"*No periodic maintenance*Long Life
This is an example of a presentation background
PPC MECHANICAL SEALS Cryogenic Mechanical Seals September 2, 2011 PPC has been manufacturing mechanical seals since 1958. Our founder was an entrepreneur, an engineer at John Crane who saw an opportunity to repair and upgrade Crane seals, eventually developing proprietary seal lines.
