The seal's compact design allows for easy installation and maintenance, reducing downtime and improving overall operational efficiency. The FS-ML35 Flygt Pump Seal's dimensional specifications are carefully engineered to withstand high pressures and temperatures, making it suitable for demanding industrial environments.
Operating Parameters
The FS-ML35 Flygt Pump Seal is built to perform under a wide range of operating conditions. It can handle pressures up to 25 bar (363 psi) and temperatures ranging from -20°C to 140°C (-4°F to 284°F), depending on the specific materials used. The seal's robust design allows for shaft speeds up to 3600 rpm, making it suitable for high-speed applications. These impressive operating parameters make the FS-ML35 Flygt Pump Seal an ideal choice for various industrial processes, including those involving corrosive or abrasive media. The seal's ability to maintain its integrity under such diverse conditions contributes to its reliability and longevity in Flygt pumps and mixers.
Sealing Face Technology
One of the key features of the FS-ML35 Flygt Pump Seal is its advanced sealing face technology. The seal faces are precision-lapped to achieve a flatness of less than one light band, ensuring optimal sealing performance. This high level of flatness minimizes leakage and reduces wear, extending the seal's operational life. The FS-ML35 Flygt Pump Seal incorporates hydrodynamic features on the sealing faces, which create a thin fluid film during operation. This film acts as a cushion between the faces, reducing friction and heat generation while improving the seal's overall efficiency. The combination of these advanced sealing face technologies contributes to the FS-ML35 Flygt Pump Seal's exceptional performance in various applications.
Materials Used in the FS-ML35 Flygt Pump Seal
Primary Sealing Elements
The FS-ML35 Flygt Pump Seal utilizes high-quality materials for its primary sealing elements to ensure durability and reliability. The stationary and rotating faces are typically made from silicon carbide (SiC) or tungsten carbide (TC), both known for their excellent wear resistance and thermal conductivity. These materials are chosen for their ability to withstand harsh operating conditions and maintain their integrity over extended periods. In some applications, carbon-graphite faces may be used for their self-lubricating properties. The selection of face materials for the FS-ML35 Flygt Pump Seal is based on the specific requirements of the application, taking into account factors such as fluid compatibility, temperature, and pressure.
Secondary Sealing Components
The secondary sealing components of the FS-ML35 Flygt Pump Seal play a crucial role in maintaining the seal's overall performance. These components typically include O-rings, gaskets, and other elastomeric parts. The materials used for these elements are carefully selected based on their chemical compatibility with the pumped media and their ability to withstand the operating conditions. Common elastomer materials used in the FS-ML35 Flygt Pump Seal include Viton (FKM), EPDM, and Nitrile (NBR). Each of these materials offers specific advantages in terms of temperature resistance, chemical compatibility, and durability. The choice of secondary sealing materials is critical to ensuring the long-term reliability of the FS-ML35 Flygt Pump Seal in various industrial applications.
Metal Components and Hardware
The metal components and hardware of the FS-ML35 Flygt Pump Seal are designed to provide structural integrity and corrosion resistance. The seal's housing and other metal parts are typically constructed from high-grade stainless steel, such as 316 or 316L, known for their excellent resistance to corrosion and pitting. In some cases, more specialized alloys like Hastelloy or Titanium may be used for extremely corrosive environments. The springs in the FS-ML35 Flygt Pump Seal, which provide the necessary face load, are often made from Hastelloy C or other corrosion-resistant alloys to ensure long-term reliability. The selection of these metal components is crucial in maintaining the seal's performance and longevity, especially in challenging industrial environments where the FS-ML35 Flygt Pump Seal is commonly used.
Performance Characteristics of the FS-ML35 Flygt Pump Seal
Sealing Efficiency
The FS-ML35 Flygt Pump Seal is engineered to provide exceptional sealing efficiency across a wide range of operating conditions. Its design incorporates advanced features that contribute to its high performance, including balanced seal faces and optimized spring loading. These features work together to maintain consistent face contact pressure, even under varying system pressures. The seal's ability to handle both high and low pressures makes it versatile for different applications within the Flygt pump range. The FS-ML35 Flygt Pump Seal's sealing efficiency is further enhanced by its precision-machined components, which minimize potential leak paths and ensure a tight seal. This high level of sealing efficiency not only prevents product loss but also contributes to improved pump reliability and reduced maintenance requirements.
Wear Resistance and Longevity
One of the standout features of the FS-ML35 Flygt Pump Seal is its exceptional wear resistance and longevity. The seal faces are made from hard-wearing materials such as silicon carbide or tungsten carbide, which can withstand the abrasive nature of many pumped media. These materials, combined with the seal's advanced face technology, result in minimal wear even under demanding conditions. The FS-ML35 Flygt Pump Seal's design also incorporates features that promote even distribution of wear across the seal faces, further extending its operational life. This longevity translates to reduced maintenance frequency and lower total cost of ownership for Flygt pump operators. The seal's ability to maintain its performance over extended periods makes it an ideal choice for applications where reliability and minimal downtime are critical.
