11.4 Flow diagrams for the correct operating pressure
The carrier’s oil flow can be restricted to achieve the right operating pressure. Restrictors can be ordered from the spare
parts list. The diagrams show oil flow at viscosity 32cSt.
11.4.1 SBU 160: 100–150 bar
The flow diagram is valid for applications with back pressure up to 10 bar. For applications where the back pressure ex-
ceeds 10 bar, a restrictor must be chosen regarding the working pressure in each specific case. In these cases, apart
from the restrictors specified in the flow diagram below, it is possible to choose a Restrictor with Ø 7.0 mm, or remove
the restrictor cartridge and work without any restriction.
