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 shaft diameter, pressure rating, and medium compatibility to ensure compatibility with equipment operating conditions. The chemical or power industry needs to pay attention to the differences in corrosion resistance and high temperature performance.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support, especially suitable for long-term stable procurement scenarios.
  • When applying mechanical seals in the food or pharmaceutical industry, attention should be paid to hygiene design standards such as surface smoothness and no dead corners to avoid contamination risks.
  • It is recommended to distinguish the applicability of balanced and unbalanced mechanical seals under different speed conditions, for example, dynamic stability parameters need to be considered for high-speed centrifugal pumps.
