3.5. Sliding Clearance
Regarding the clearance between the case wearing ring and the
impeller sliding surface, the design value for the impeller whose
material is FC is φ0.4 mm, and the tolerance value is φ1.0 mm. The
design value for the impeller whose material is SCS is φ0.6 mm,
and the tolerance value is φ1.2 mm.
If the tolerance value is exceeded, replace the case wearing ring.

period
