Mechanical Seals for Industrial Pumps
YUEMAX supplies mechanical seals for industrial pump applications. Seal selection is based on the actual fluid, temperature, pressure, speed, solids content and operating conditions rather than model name alone.

Selection Based on Service Conditions
For chemical, petrochemical, water-treatment and other industrial services, the correct mechanical seal must match the pumped medium and equipment conditions. We evaluate fluid compatibility, operating temperature and pressure, shaft size, rotation speed, solids content and the required seal arrangement before recommending a solution.
Particle Size & Solids Matter
For fluids containing crystals, powders or suspended solids, please provide the particle size or mesh information together with the approximate solids concentration. This is especially important when evaluating seal-face materials, flushing requirements and the most suitable seal structure.
Replacement & Custom Matching
Replacement mechanical seals can be evaluated from the original model, drawing, dimensional data or physical sample. For pump-maintenance projects, clear photos of the complete seal and critical dimensions help us confirm the correct replacement more quickly.
