Problems with mechanical seals in ordinary centrifugal pumps
Thread Content
For ordinary centrifugal pumps, is the mechanical seal and the sealing ring that directly contacts the pump casing provided by the mechanical seal manufacturers or purchased separately?
It’s fine if the manufacturer provides it; it’s also okay to purchase it by conducting your own surveys and measurements
Mechanical seals are supplied as a complete set; components that do not belong to mechanical seals will not be provided by the manufacturer.
It can be purchased from the pump manufacturer, or bought separately according to the mechanical seal model; other seals can be acquired based on their dimensions.
You can directly contact the original pump manufacturer for purchase, avoiding the need for measurements or wasting time searching around. . . . .
Can we ask the manufacturer to come and conduct surveys on site? After that, we can simply report the pump’s serial number and proceed with the purchase
You are referring to the O-rings that come as part of mechanical seals; they are all supplied together with the mechanical seals. It’s not easy to purchase them on one’s own, as different types of mechanical seal O-rings are made from different materials
Yes, it’s also a sealing ring, but it’s in direct contact with the pump body – isn’t it provided by the pump manufacturer?
It can be purchased independently or from manufacturers of mechanical seals; however, when purchasing on one’s own, it is important to pay attention to the specifications, model, and material of the sealing ring.
Actually, we had bought sealing strips before and made our own O-rings, haha.
Is it the O-ring of the mechanical seal’s static ring? Is it the seal ring at the connection between the mechanical seal gland and the pump body? If it is a mechanical seal, it is generally provided by the mechanical seal manufacturer along with the seal itself ； If it is a gland seal ring, it can be designed after measurement, taking into account the properties of the medium, and then purchased
