Separator unit (2N01)
Each engine must have a dedicated lubricating oil separator and the separators shall be
dimensioned for continuous separating.
If the installation is designed to operate on MDF only, then intermittent separating might be
sufficient.
Separators are usually supplied as pre-assembled units.
Typically lubricating oil separator units are equipped with:
●
Feed pump with suction strainer and safety valve
●
Preheater
●
Separator
●
Control cabinet
The lubricating oil separator unit may also be equipped with an intermediate sludge tank and
a sludge pump, which offers flexibility in placement of the separator since it is not necessary
to have a sludge tank directly beneath the separator.
Separator feed pump (2P03)
The feed pump must be selected to match the recommended throughput of the separator.
Normally the pump is supplied and matched to the separator by the separator manufacturer.
The lowest foreseen temperature in the system oil tank (after a long stop) must be taken into
account when dimensioning the electric motor.
Separator preheater (2E02)
The preheater is to be dimensioned according to the feed pump capacity and the temperature
in the system oil tank. When the engine is running, the temperature in the system oil tank
