Lubricating oil filtration

Lubrication oil filtration at gearboxes

In oil tankers, container, passenger and cargo ships, filtration solutions are responsible for uncompromisingly clean performance under the toughest conditions. Longer service life, higher operational reliability, less maintenance and careful use of resources – the performance of our systems pays off for the environment.

Transmission oil filters have to deliver maximum efficiency. They ensure reliable operation around the clock hydraulically switchable reduction gears to avoid a complete standstill of the ship.

Challenge

  • Only one shared filter unit shall be installed for the filtration of the lubrication oil and the oil for the hydraulic transmission shifts
  • The filter unit shall be easily accessible from the outside and the maintenance has to be possible without interruption of operation
  • The filter unit has to be approved by the established certification offices in the marine industry

Technical data

  • Viscosity: up to 220 mm² /s at 60 °C
  • Filtration Rate: 10 µm
  • Operating pressure: 28 bar

Solution statement

  • The lubrication oil is filtered by a Filtration Group duplex filter of the Pi 210 or Pi 241 series with a 10 μm Premium Select filter element
  • Thanks to the duplex design of the Filtration Group Filters the elements can be changed at full load by a simple switch of the operating filter
  • The Premium Select Technology ensures high cleanliness levels of the lubrication oil and extends the lifetime of bearings
  • The Inline filter could be installed easily directly at the gearbox housing

Customer value

  • Every filter was adapted to the different requirements of the different gearbox sizes
  • Filtration Group Premium Select elements provide an up to 30% higher dirt holding capacity at reduced differential pressure in combination with a well-defined high retention rate
  • This leads to significantly reduced maintenance requirements
  • The element change can be performed at any time, if required at full load
  • Operating pressure up to 32 bar possible
  • The Filtration Group Pi 210 and Pi 241 Series are approved by the established certification offices in the marine industry
