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.
