Welded Metal Bellows Seal

Metal Bellow Seals of MB1 are commonly used for moderate Temperature Oils & Hydrocarbons, MB1 provides a high degree of axial flexibility to compensate for lack of concentricity of the shaft or misalignment due to thrust movement of the shaft. Moreover, these seals are used for high temperature application such as refinery, Petrochemical, and Oil & Gas industries. These seals do not have a dynamic o rings eliminating the fretting of Shaft or Sleeve. Salient features: Welded Diaphragm Bellow Design Suitable for High Temperature Media. Axial compensation of movement 1 mm. Perfect for standardization purposes. No Dynamic O Rings Inherently Balanced Design Applications: Specially used in paper and pulp Industries, petrochemicals, petroleum refinery etc. Material: Seal Faces: Ceramic/Sic/Carbon Vs Ceramic/RB Sic./TC Secondary Seals: Viton/PTFE/GFT/FFKM Metal Components: SS-316/Hast-C/Carpenter-42 Bellow: AM-350/Hast-C276/Inconel-718

This design is comply with api682 technical requirements and has the flexibility to fit into ansi+ and din standard pumps

Supplier: Welded metal bellows mechanical seal, mechanical seal auxiliary system, magnetic drive pump, coupling, gas-liquid flow screw power machine, precision casting

Mechanical metal Material: HT250 Weight: 45kg Manufacture process: Sand casting

Parameters: 1. Pressure Limits: 0~2.5 Mpa (0~25 bar) 2. Temperature: -100~425 C 3. Speed:0~3600 r/min 4. Shaft Size Limits: 25~350 mm 5. Medium: all kinds of chemicals, high and low temperature medium, corrosive medium. Main Features: 1. According to API682 standard (for the shaft size of 20~110 mm) 2. Extremely lower leakage and abrasion loss. 3. Dual-face tandem contacting type mechanical seal in 3CW. Adopt metal bellow expansion joint, when the sealing liquid side pressure is 0.2~0.3 Mpa higher than the medium side, it will take effect to stop the process medium to leak out. 4. The wave plate is designed to optimal bevel to minimize reduce the welding heat effect destressing. When it rotating, the particles will be thrown out to keep the cleanness of the wave plate. 5. Simple structure with compact size. 6. Adjustable structure and material components based on specific working condition. 7 .Cartridge design, easy to install. Application: Suits for various chemical fluids, no matter it's high temperature, or low temperature or corrosive fluids.
