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

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 indicated numbers in the tables below are average values in microns (µm).
