Lagersmit - Pump Gear Bulkhead Seal
Conventional seals are not able to perform under harsh dredging conditions that cutter suction dredgers (CSDs) encounter every day during their activities. For this sole purpose, Lagersmit has developed a highly reliable pump gear bulkhead sealing solution, which can handle large bulkhead and shaft deformations and can operate in abrasive environments at draughts of 16 m. It is designed to keep you going and takes the next step in both performance and reliability.
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.
- Proven seal technology that protects the pump gear machine room
- Zero emissions to the water environment
- Pressure compensation at varying depths
- Operates at greater depths (>15 m below the water line)
- Flexibility and (bearing) support to manage 5 mm of radial displacement
- Minimal wear on lip seals and the support bearing
- Condition Monitoring for planned maintenance and minimal risk of sudden failure
- Continued operation if Lube Oil Unit needs to be maintained
