Mechanical seal is a device, which helps join systems or mechanisms together by preventing leakage containing pressure or excluding contamination. They are required for all closed system circulating pumps.
Mechanical Seals consists of two basic parts, they are a rotating elements attached to the pump shaft and a stationary element attached to the pump casing. Each of these elements has a highly polished sealing surface. The polished faces of the rotating and stationary elements come into contact with each other to form a seal that prevents leakage along the shaft.
Mechanical Shaft provides the best gripping force of any core shaft. It is designed with greater structural strength and a powerful expansion mechanism to handle the heaviest roll weights at high speeds.
Mechanical steam traps are operated by the difference in density between steam and condensate. All use a float in some form to operate the valve to let condensate drain from the system. It includes an inverted bucket, open bucket and float and thermostatic types. All can operate at or near steam saturation temperature because trap operation is dependent on the density difference between steam and water, which is about 700 to 1. all mechanical traps respond quickly to changing loads and most have large turn down ratios.
