Many – too numerous to list, covering a vast range of designs, sizes, and materials suitable for a never-ending range of applications. Some designs conform to International Standards such as BS1399 and DIN 3760 for metric sizes and seal types, but the majority have been manufactured to suit particular applications – hence the enormous selection available. This blog is intended to assist in this selection and will consider seal type, materials, and sizes.
Another critical factor to consider is the type of seal most suitable for particular machinery. When selecting your mechanical sealing solution, assess your machine’s shaft speed, temperature, pressure, environment, and the medium coming into contact with the seal during an operation. These factors help determine the color, size, sealing element, lip material to choose from, and if it can be sealed out or sealed in.
