• The sealing surfaces are lapped within specification
• Perpendicularity and concentricity between the shaft and the seal
chamber face and bore respectively
• Freedom of movement of the spring loaded components in axial
direction
• Axial and radial shaft movements within Flowserve or OEM toler-
ances whichever is the tightest.
• The seal is run under the conditions for which it was selected.
• The equipment in which the seal(s) is (are) installed is operated
within normal parameters (no cavitation, excess vibration etc.)
• Prevention of sedimentation on shaft or sleeve surfaces caused by
for instance crystallisation or polymerisation
• Permanent seal liquid film between the sealing surfaces.
If these function conditions are not fulfilled, the consumption of
product, for example, is increased and parts of the product can
escape into the atmosphere. Other effects can include high com-
ponent temperatures.
See the directive 9/9/EC, 1999/92/EC and EN 1363-5.
Failure to meet these requirements will result in excessive leakage and/
or shortened seal life.
