3.13 Extra clearances
To handle extra clearances following clearance classes are defined:
C0 = Pump cover axial clearance set at minimum
C1 = Standard clearance (not indicated because standard)
C2 = ~2 x standard clearance
C3 = 3 x standard clearance
C1 = Standard clearance (not indicated because standard)
C2 = ~2 x standard clearance
C3 = 3 x standard clearance
To indicate required clearances a code of 4 digits, xxxx, is given on the order.
The figure ‘‘1’’ stands always for ‘‘normal’’ and no special action is considered.
The figure ‘‘1’’ stands always for ‘‘normal’’ and no special action is considered.
The indicated numbers in the tables below are average
values in microns (µm).
