11.1.7 Shims specifications
How to use the diagrams:
1
Find the pump speed in [rpm] on the horizontal axis.
2 Go straight up and meet the proper discharge-pressure line.
3 At that point, go straight to the left and read the number of shims on the vertical
axis.
•
When the product temperatures are above 60 °C (+140 °F) always use one shim
less than indicated in the diagrams.
•
Always round up the number of shims.
•
Each diagram gives the number of shims per pressing shoe.
•
Shim both pressing shoes identically.
* All bolts are class 8.8.
** Due to creeping of the hose material, the hose clamp force initially reduces in time. If leak-
age starts, re-tighten the hose clamp to the specified torque level. The listed torque values
apply to a new and properly greased hose clamp. See also §
8.6.3 point 10 for extra
instructions and hose clamp installation.
