Metso - Mechanical Slurry Seal

Metso - Mechanical Slurry Seal

A new flexible fixing of the seal face and unique locking pin allow the seal to tole-rate
both vibration and excessive shaft deflection. Static and rotating seal parts exposed to
slurry have been geometrically harmonised to minimize turbulence and secondary flow streams, thus reducing wear in heavy slurry applications. Patented design with the springs located on the atmospheric side, protected from both slurry and barrier liquid, eliminates hang-up problems or clogging of the springs. The design also accepts axial movements of up to ± 9 mm, enabling operators to take advantage of the Metso adjustment features without resetting the assembly. The dual balanced design can operate with pressurised barrier liquids, either higher or lower than the slurry pressure, while it’s unique hydraulic arrangement also allows the seal to operate under vacuum conditions. Seals are supplied with metal parts in AISI 316, springs in HASTELLOY™,
O-rings in Viton™ and seal faces in a unique Silicon Carbide compound.

Bulkhead History & Uses :
These fittings are specialized components used in fluid systems to create a sealed connection through a barrier such as a tank, wall, or panel. These fittings allow for the passage of fluids, gases, or electrical wiring while maintaining a leak-proof seal. They are commonly used in industries such as plumbing, automotive, aerospace, marine, and industrial manufacturing. Here's a more detailed description of bulkhead fittings:

  1. Construction:
    Bulkhead fittings typically consist of three main components - two threaded components (often referred to as "nuts") and a central component that goes through the barrier. The nuts are threaded onto the central component from both sides of the barrier, compressing sealing gaskets or washers between them to create a watertight and airtight seal.

  2. Materials:
    Bulkhead fittings are manufactured from various materials to suit the specific application and the type of fluid or gas being conveyed. Common materials include stainless steel, brass, plastic, and various engineered polymers. The choice of material affects factors such as corrosion resistance, pressure tolerance, and compatibility with the media being transported.

  3. Types: There are several types of bulkhead fittings, including:

    • Threaded Bulkhead Fittings: These fittings have threads on both sides of the barrier, allowing them to be screwed into the barrier from either direction. This is the most common type of bulkhead fitting.

    • Flanged Bulkhead Fittings: These have flanges on both sides of the barrier, which are bolted together to create a seal. Flanged fittings are often used for larger pipes and higher pressure applications.

    • Compression Bulkhead Fittings: These fittings use compression fittings on both sides of the barrier to create a seal. They are commonly used for plastic tubing and applications where threaded fittings might not be suitable.

  4. Applications:

    • Plumbing: Bulkhead fittings are used in plumbing systems to pass pipes through walls, floors, and ceilings while maintaining a watertight seal.

    • Automotive: In vehicles, bulkhead fittings are used to pass hoses or wiring through firewalls, floors, and other barriers.

    • Aerospace: Bulkhead fittings are critical in aircraft to create sealed passages for wiring, tubing, and fluid lines through the aircraft's structure.

    • Marine: In marine applications, bulkhead fittings allow for the passage of pipes, cables, and control lines through the hull of a ship or boat without compromising its integrity.

    • Industrial: In industrial settings, bulkhead fittings are used to connect pipes, hoses, and cables through equipment housings or structural barriers.

Bulkhead fittings come in various sizes, thread types (NPT, BSP, etc.), and configurations to accommodate different requirements. Proper installation is essential to ensure the integrity of the barrier and prevent leaks or breaches in the system.
