Chamber Concentricity Runout
Maximum Acceptable Runout
0.001 mm per mm (0.001" per inch)
of indicated diameter
5.2 Position and lightly secure the equipment casing in place.
5.3 Seal chamber concentricity should be less than 0.38 mm (0.015").
Poor shaft alignment can reduce seal life. See Figure 12.
5.4 Seal mounting runout (perpendicularity) should be less than 0.001 mm per mm
(0.001" per inch) of indicated diameter. See Figure 13. When the equipment case
and shaft are properly aligned, secure the case in place.
5.5 If the seal is mounted directly on the shaft, rather than on the equipment sleeve,
install the impeller spacer sleeve (possibly modified).
5.6 Install the impeller and case.
5.7 Make any necessary impeller adjustments.
Warning: Loosen the bearing assembly and drive belts only enough to make the
adjustments. Fully retighten the bearing assembly and belts after adjustment.
5.8 Slide the seal cartridge up to the equipment case. Insert the retaining bolts through
the gland holes and screw into the threaded holes on the face of the equipment case.
Tighten the retaining bolts evenly in opposing pairs. See Figure 14.
