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 .

Available in low- and high-temperature designs, the ECS is a dry-running seal for emission containment and safety/backup that successfully controls VOC (volatile organic compounds) and VHAP (volatile hazardous air pollutant) emissions. The ECS provides an economical alternative to dual seals with liquid barrier systems. As a self-contained cartridge, the outer ECS is used with either a rotating or stationary other primary seal and will successfully contain any nominal leakage from the primary seal. The seal also acts as a backup providing and additional level of safety during process or system upsets.
