Installation and Maintenance
Installation Method	Axial Installation	Installed axially onto the pump shaft following a standardized procedure for correct alignment
Installation Torque	12 - 18 N·m	Recommended torque range during installation to ensure a secure fit without over - tightening
Maintenance Cycle	Every 4000 operating hours	Regular inspection and maintenance every 4000 hours to check for wear, leakage, and proper function
Storage Conditions	Store in a dry, cool place at 5ºC - 25ºC, away from direct sunlight and chemicals	Ideal conditions to preserve the seal's integrity during storage
Quality and Certification
Service Life	Approximately 2 - 3 years under normal conditions	Expected service life with proper operation and maintenance
Leakage Rate	≤0.1 mL/h	Maintains a low leakage rate to ensure system safety and environmental protection
Certification Standards	ISO 9001, API 682 (if applicable)	Meets international quality management and industry - specific standards for mechanical seals
Other Characteristics
Vibration Resistance	Withstands vibrations of 6 - 45 Hz and amplitude 0.5 mm	Designed to maintain sealing performance in vibrating environments
Self - lubricating Property	Seal surfaces have a self - lubricating treatment to reduce friction	Enhances the seal's lifespan and reduces energy consumption

 

 

Queeny design engineers are able to produce a seals solution for the most basic applications,to those that are extremely complicated and unique. We are able to provide you these solutions supported by life test data and years of excellent field performance.As your partner, we provide sealing solutions for centrifugal pumps,agitators and other rotating equipment, and help you consolidate your brand and market position.

Mechanical sealing adopts the principle of mechanical friction sealing, which has excellent sealing performance, which can effectively prevent leakage and protect the safety of the environment and equipment. Compared with traditional packing seals and rotary seals, the sealing effect of mechanical seals is more reliable.

 

Our products are made of high quality materials and manufacturing processes, with a long service life and low cost of use. It can effectively reduce the maintenance costs and operating costs of equipment .

 

Our mechanical seals are designed to be easy to service and replace,simply by removing the sealing components and replacing the sealing surface and sealing ring. Compared with other sealing forms, our products are more convenient to repair and replace.

 

Mechanical seal is suitable for high temperature, low temperature, high pressure, vacuum and corrosive media and other complex environment, to ensure the stable operation of the equipment.
