The Basics of Mechanical Seals

- This video is a very brief overview of the basics of Mechanical Seals and their operation.
They are used primarily in pumps to allow a rotary shaft to protrude from a housing but still seal around the gap between both of these parts. They comprise stationary and static face made from high grade carbon composites and a stainless steel spring and body.

Studying for my test and I couldn’t wrap my head around face seals (axial mechanical seals) this cleared everything up! Awesome video, thanks!
No problem, glad we could help! Good luck!
impressive and just easy to understand. thank you very much!
very clear explanation. Thank you 👍
I need asking about O ring in mechanical seal where it is
How much pressure with stand this seal
Throughout good Explanation
What is the difference between NPR and ACM
Sir what is fins???why it is provided in motor and gearbox??
I am having a problem fixing seal of pumping machine after fixing correctly it still refuse to pump water.
Please can anyone give a guide on how to calculate the position of the rotating and stationary part of this mechanical seal in a pump?
How the stationary part of the seal is rotating with the rotary face? can you please explain that?
Hi there. The stationary is not rotating. To make it clearer you can see our logo on the top of the stationary and it does not move.
@@totallyseals4967 yeah but it looks like the half part (end part of stationary face )of it is rotating in the animation
It does look like it but it’s not. There’s a reflection from the rotary face. The stationary face is one piece so no part of it is moving. Hope that helps.
@@totallyseals4967 thanks a lot
Sir, How Can we measure the size of a mechanical seal And in general what are the different sizes of a mechanical seal? Please reply me.
Well ,am not an expert on this subject. With this caveat , let me try to answer you . A seal is measured by internal diameter, external diameter and the height .
To this,there as many seal sizes as there are different shaft diameters. Good luck
To reduce the friction and high temperature what type of cooling system is used in that area.
There’s a thin layer of the fluid your pumping between the rotating and fixed surface. Look up pipe plans because there’s a lot of different ways you can do it.
The layer is around one micrometer thick but it varies between applications and tolerances

Make a video on carbon mechanical seal and tc seal
Hello, we will try!
@@totallyseals4967 try to explain with parts names
Relation between mechanical seal , gland and stuffing box
Stuffing box is a seal to stop leaks for a rotating or sliding shaft. Gland is a type of stuffing box seen in taps and also in some boats. Mechanical seal is a different sealing system that was introduced more recently.
The mechanical seal is normally set inside the stuffing box (back in the day people literally used to stuff a box with all sorts of stuff to prevent leaking). The gland is an additional part that "locks" the mechanical seal in place. Think of it like putting leftover in a tubaware. The food is the mechanical seal, the tubaware is the stuffing box, and the lid that goes on top of everything is the gland to keep everything in place.
