Overview
For turbo-compressors, steam turbine gear units and large high-speed reducers, the lube oil system is a system in its own right: it draws oil from the tank, pressurises, filters and cools it to the set temperature, feeds the gearbox and bearings, and collects the return oil.
LOS systems are engineered and delivered per project. Main and standby pumps are usually our GL-S three-screw or GL-E gear pumps, with redundancy and instrumentation configured to the customer’s specification and API 614 design principles.
-
Automatic standby pump
If the main pump fails or oil pressure falls below set-point, the standby pump starts automatically — oil never stops.
-
Duplex filter, online changeover
Duplex filter with differential-pressure alarm; switch and clean elements while running.
-
Closed-loop temperature control
Cooler, electric heater and thermostatic valve keep supply oil within the set range.
-
Monitoring and interlocks
PLC monitors pressure, temperature, level and differential pressure, interlocks with the machine control system and supports remote monitoring.
