MAN B&W S35MC-C S35MC L35MC Stuffing Box

MAN B&W S35MC-C S35MC L35MC Stuffing Box Description:

The high-quality MAN B&W S35MC-C, S35MC, and L35MC stuffing box makes sure that marine diesel engines seal properly, which keeps oil from leaking and getting dirty for the best performance.

The MAN-B&W stuffing box for the S35MC-C, S35MC, and L35MC engines is an important part at the bottom of the cylinder frame. It seals the route for the piston rod between the scavenge air gap and the crankcase. It has specific scraper and sealing rings that keep scavenging air from getting into the crankcase while scraping off dirt and oil from the piston rod and sending it back to the crankcase through dedicated drains. This design uses less oil, needs less maintenance, and works well in tough marine settings.

Model Specifications:

Main Characteristics:

1) The top scraper ring on this advanced multi-ring system keeps scavenging sludge from getting in, and the bottom scrapers quickly remove crankcase oil from the piston rod.

2) Sealing rings in the middle of the block keep air and possible exhaust gases from getting into the crankcase, which makes the engine safer and more efficient.

3) Integrated drain routes gather scraped oil, debris, and carbon deposits and send them back to the crankcase to save them from getting dirty.

4) The strong two-part bolted housing design makes it easy to check and maintain without taking the whole thing apart.

5) Optimized for tropical conditions (up to 45°C air and 32°C ocean) and works with IMO Tier II compliant engines with very little oil carry-over.

Advantages:

• Ensures that crankcase oil is safely separated from scavenging air, which stops contamination and explosions.
• Stops scavenging fires by keeping cylinder oil and combustion gasses from getting into the crankcase.
• Scraping rings work well to get rid of oil and dirt off the piston rod, and the drains safely send it back to the crankcase.
• The simple, tried-and-true design makes it very reliable, easy to care for, and lasts a long time.
• Allows for huge gaps in the piston rod while yet sealing well under high pressure.
• Bronze sealing rings and steel scrapers don’t wear out, and garter springs keep them in touch with each other.

​

​Applications:

• Mostly used in MAN B&W S35MC series marine propulsion engines for tankers, container ships, and bulk carriers that need solid piston rod sealing.
• In low-speed two-stroke diesels, this is necessary to keep the scavenge air area and crankcase from getting dirty.
• Ideal for overhauling and replacing spare parts in engines with a lot of hours on them to restore sealing integrity and lower lube oil use.
• Continuous operation is possible in harsh marine settings with high humidity and lots of vibrations.
