The lubricating oil sump is of wet sump type. Dry sump is an option for main engines.
The direct driven lubricating oil pump is of gear type and equipped with a pressure control valve. The pump
is dimensioned to provide sufficient flow even at low speeds. A stand-by pump connection is available as
option. Concerning flow rate and pressure of the engine driven pump, see Technical data.
The pre-lubricating oil pump is an electric motor driven gear pump equipped with a safety valve. The pump
should always be running, when the engine is stopped. Concerning flow rate and pressure of the pre-lub-
ricating oil pump, see Technical data.
The lubricating oil module built on the engine consists of the lubricating oil cooler, thermostatic valve and
automatic filter.
The centrifugal filter is installed to clean the back-flushing oil from the automatic filter.
All dry sump engines are delivered with a running-in filter before each main bearing. These filters are to be
removed after commissioning.
