How does it work?
The Pump Gear Bulkhead sealing system consists of a floating seal with a protection cover and a lubrication system with a Supreme Ventus® system, which are equipped with all necessary sensors for controlling and monitoring the seals. The Pump Gear Bulkhead seal is installed on the underwater pump shaft and is mounted to the bulkhead of the underwater pump gear machine room.
The “floating” seal will follow the radial shaft movement by means of a segment with an integrated white metal slide bearing. This way conditions for proper static alignment and run-out are met automatically.
All oil connections are made on the inboard side of the seal; no extra passages through the bulkhead are needed.
The Supreme Ventus system decreases the pressure differences over the lip seals, meaning the heat generated by friction will be less, to lengthen the lifetime of the Supreme lip seals.
An additional benefit of the Ventus system is the ability to monitor the lip seal wear by draining any leakage into a drain tank, from which samples can be taken. The leakage rate illustrates the amount of wear on your lip seals.
The Ventus system has been used for seals in propulsion systems for over a decade now and it is believed by many ship owners and propulsion manufacturers to be a valuable asset to your sealing system.
The lubrication system comprises two lube oil systems. The lube oil system circulates the oil and controls pressure, flow and temperature in order to build up an appropriate lubrication film for the white metal slide bearing.
The lubrication system has a redundant pump set and filter, making it possible to perform maintenance while the dredging operation continues.
Lagersmit is not only responsible for the development and production of the sealing system, but also performs the installation of the seal and commissions the complete sealing system and system controls.
