Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of mechanical seals, it is recommended to prioritize checking key technical parameters such as pressure range, temperature adaptability, and medium compatibility to ensure compatibility with equipment operating conditions.
  • In different application scenarios such as chemical or electrical engineering, the selection of materials for mechanical seals needs to consider differences in corrosion resistance and wear resistance, such as distinguishing the applicable environments of graphite and silicon carbide.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and enterprises with industry data support or platform statistical information.
  • In actual procurement, attention should be paid to the axial compensation capability and vibration adaptability of mechanical seals, which are particularly crucial for the long-term stability of high-speed pump bodies and other equipment.
