Number of dynamic seal points in horizontal centrifugal pumps
Thread Content
I would like to ask how to calculate the number of dynamic seal points for this type of horizontal centrifugal pump
“Regarding the number of dynamic sealing points: the two ends of the volute and the shaft are where the dynamic sealings are located. I need to know how to calculate this – please clarify.
Just ask the manufacturer directly.
A dynamic sealing point refers to the sealing location between two components that are in relative motion (rotation or back-and-forth movement); for example, an axis seal counts as one dynamic sealing point, and the two ends of a motor also constitute dynamic sealing points on the equipment. You’ll need to refer to the equipment drawings – look along the axis to find them
Starting from the motor connection side: drive end bearing, two gland covers on each side, 2 in total； Mechanical seals on both sides, 2 ； The non-drive end bearing is located on the side close to the impeller, 1 piece. So there are a total of 5 dynamic sealing points.
It doesn’t have a motor, right! 2 more need to be added at both ends of the motor
Should there not be another one on the motor side as well?
