How To Choose High-quality Mechanical Seals

1. Movement direction: First determine the movement direction of the seal at its position, such as reciprocating, rotating, spiral, or fixed.
2. Sealing focus: For example, determining whether the active point is a rod seal on the inner diameter or a piston seal on the outer diameter.
3. Temperature level: Refer to the original mechanical instructions or evaluate the working temperature according to the actual working environment to determine the required materials.
4. Size: Most users will choose based on the old samples they have used, but after a period of use, the original size of mechanical seals will be greatly affected by factors such as temperature, pressure, and wear. Sample selection can only be used as a reference. A better method is to measure the size of the metal groove where the mechanical seal is located, which will result in higher accuracy.
5. Pressure level: Refer to the original mechanical usage instructions for relevant data.
