The issue with the direction of rotation of the pumping ring
Thread Content
This post was last edited by Ding dong_s978C on 2024-11-9 09:43. Look at the diagram: if the pump rotates counterclockwise, then should this seal be a drive-end seal or a non-drive-end seal? What if it’s installed incorrectly? The rotation direction of the pumping ring will then be reversed. I’m not sure how to tell which direction is correct Is it based on the spiral direction or something else?
No images. As the name implies, the drive side is the side with the motor.
If the pump rotates counterclockwise, this seal should be the non-driving-end seal. The direction of rotation of the pumping ring is usually determined by the rotation direction of the pump shaft. If it is installed incorrectly, it can indeed cause the rotation direction of the pumping ring to be wrong, which usually affects the proper sealing performance and the operating efficiency of the pump. During installation, make sure to configure it correctly according to the manufacturer’s instructions. .
The image is in another post; this post forgot to include the image. I didn’t know how to delete this post, so I created a new one instead
Hello, the seal diagram has just been re-uploaded. Please take a look and determine whether the seal shown in this diagram is one at the non-driving end or at the driving end How do I determine which side to install it on?
Check whether the designation on the end cap interface is BO (LBO) or BI (LBI); use this to determine the flow direction of the isolation (buffer) fluid, and then decide which side it should be installed on.
The rotating ring of this mechanical seal does not have a specified rotation direction; it is the pumping ring that requires such a specification. The mechanical seal housing also has requirements regarding rotation direction, with the rotation directions on the drive side and the non-drive side being opposite to each other. Be careful not to install it incorrectly
When the manufacturer arrives, they will definitely indicate which end it is. What I mean is, if the manufacturer doesn’t provide any indication, how can one determine whether the seal is on the drive side or the non-drive side based solely on the direction of the bolts on the pump’s rotating ring? Just as shown in this diagram, the pump rotates counterclockwise when viewed from the motor side. Should this seal be installed on the drive side or the non-drive side? Also, is the rotation direction of this pumping ring clockwise or counterclockwise?
What you’re saying is too general; some covers don’t have any markings at all The most accurate method is to determine whether it is the drive end or the non-drive end by checking the rotation direction of the pumping ring
You can’t even tell which way to enter and which way to exit – is it useful to look at the rotation direction? When the axial pumping ring rotates in the forward or reverse direction, the flow direction of the isolation fluid changes accordingly.
Axial pumping ring, can it be rotated clockwise? Can I rotate counterclockwise?
