How are made mechanical seals<\/strong><\/a>, and how do they work in pumps<\/strong>? When I first started working as a technician, I was wondering how it was possible for a mechanical seal to avoid leakages of fluids on a rotating shaft<\/strong>. This is in fact the purpose of a mechanical seal, to avoid the leakage of liquids on a rotating part, functioning as a seal where there is a rotor that gets water under pressure<\/strong>.<\/p>\n

And so, how is made a mechanical seal? A mechanical seal is basically made by two parts<\/strong>, one fixed and one rotating. The fixed part<\/strong> is mounted on the main body pump, it achieves sealing through an O-ring<\/strong> and has a grinded and very smoothed surface that gets in direct contact with the mobile part.<\/p>\n

The rotating mobile part<\/strong> is mounted on the shaft, and so this is integral with it. Also in this case, sealing is achieved with an O-ring, so a classical seal, on the shaft side. The seal between the two parts is ensured by the contact between the surfaces that are so very much smooth that avoid any fluid\u2019s leakage<\/strong>, being it both water or oil<\/strong>.<\/p>\n
