 
Durashield EA Series engineered seals effectively address some of the
most problematic processing applications. High pressures, excessive shaft
speed and difficulty to adjust are just a few common reasons for
early seal failure. EA Series seals address these problems
while meeting the requirements of a positive pressure shaft seal.
EA Series seals are widely used throughout the bulk materials processing industry in many types of abrasive wet or dry situations.
Although EA Series seals are designed to fit C.E.M.A. installation standards for
4-bolt flange bearings they are not capable of being mounted
between the bearing and end plate of equipment. Please allow for
proper clearance between the seal and bearing.
EA Series seals are custom built to meet your processing requirements!
