FAQ's of Double Seal (Mill):

Q: How does the Double Seal (Mill) prevent leakage and contamination?

A: The Double Seal (Mill) uses a double-acting configuration with advanced materials such as carbon, SiC, or tungsten carbide for the seal faces and high-performance elastomers for secondary seals. This combination, along with precisely engineered spring systems and cartridge mounting, ensures minimal leakage, effective contamination prevention, and reliable operation even under demanding mill conditions.

Q: What installation options are available for the Double Seal (Mill)?

A: This seal can be installed using either a cartridge or gland-mounted design, offering flexibility depending on the application's needs. Both mounting types provide straightforward assembly, precise alignment, and improved reliability, making them suitable for a variety of pumps, agitators, and mill equipment.

Q: Where can the Double Seal (Mill) be used?

A: This seal is designed for use in pumps, agitators, and milling systems primarily in the chemical, paper, and general processing industries. Its materials and robust structure make it ideal for harsh environments that require strong chemical resistance, high pressure, and effective leakage control.

Q: What are the benefits of using balanced versus unbalanced rotary ring types?

A: Balanced rotary ring designs offer improved pressure handling and reduced face wear, while unbalanced types provide a simpler structure for lower-pressure systems. Selecting the appropriate type enhances performance, extends seal life, and suits the specific conditions of your equipment.

Q: How long can I expect the Double Seal (Mill) to last and what maintenance is required?

A: With superior materials and design, the Double Seal (Mill) offers a long service life and minimal maintenance under recommended operating conditions. Routine visual inspections and occasional replacement of secondary sealing elements may be all that's necessary to maintain reliable performance.

Q: What operating parameters does the Double Seal (Mill) support?

A: This seal is engineered to work at pressures up to 25 Bar, speeds up to 25 m/s, and temperatures ranging from -20C to +180C. It supports shaft diameters from 25 mm to 150 mm, accommodating a wide range of mill and process equipment sizes.

Q: Is the Double Seal (Mill) compliant with international standards?

A: Yes, the Double Seal (Mill) is manufactured to meet international mechanical sealing standards, ensuring reliable operation, safety, and compatibility in global industrial applications.
