Mechanical Seals

Mechanical Seal Suppliers UK – For virtually any application

M Barnwell Services’ Mechanical Seals are an excellent solution for sealing rotating shafts. These seals feature two precisely lapped faces arranged perpendicular to the shaft axis, earning them alternative names such as Radial Face Seals, Pump Seals, or Packings.

In this mechanism, one face is affixed to the equipment casing or vessel, while the other is securely attached to the rotating shaft, moving in tandem. To mitigate frictional heat and wear, a lubricant film is maintained between the seal faces, akin to the functionality of thrust bearings.

These seals exemplify durability and superior quality. Key benefits encompass reduced wear, minimised heat generation, lower energy consumption, decreased maintenance needs, precise control of shaft leakage, and overall cost reduction.

Experience the reliability of our seals, designed to optimise equipment performance. Whether you seek to enhance wear resistance or minimise energy consumption, our seals deliver on their promises.

Additionally, explore our extensive inventory, which includes a diverse range of specialist Cartridge Seals. Trust M Barnwell Services for top-notch Mechanical Seals that ensure optimal equipment functionality and longevity.
