Performance Capabilities

1. Our core business focuses on the manufacture, precision installation, global export and wholesale of a comprehensive quality range of industrial mechanical seals. From single spring seals to advanced dry running reverse balance seals, every product is engineered to deliver consistent sealing performance across chemical, water treatment, food processing and HVAC industries.
2. We maintain full compatibility with the world’s leading pump brands, supplying complete mechanical seal ranges for Flygt, Grundfos, APV, ABS, EMU, GEA, Lowara and many other well-known pump systems, making us a trusted one-stop seal replacement partner for global industrial operators.
3. Supported by our in-house ISO9001 certified production facility, we go far beyond standard catalog offerings: we can design, test and manufacture custom mechanical seals fully tailored to your unique specifications, whether you provide an existing sample, a detailed technical drawing, or a full set of custom application requirements.

1. Q: Are you a factory or a trading company?A: We are a professional mechanical seal manufacturing factory based in Ningbo, China, with a dedicated in-house international trade team. This setup lets us cut out middleman costs, keep full control over production quality, and deliver fast, responsive after-sales support directly to global industrial buyers.

2. Q: Can I get a sample before placing a bulk order?A: Yes, absolutely. Standard seal samples are available on request and are completely free — you only cover the small courier shipping fee for delivery to your location. It’s a low-risk way to test our product quality before committing to a larger order.

3. Q: Where is your factory located? How can I arrange a visit?A: Our full production facility is based in Ningbo, one of China’s major industrial port cities. You can fly directly to Ningbo Lishe International Airport, or land at Shanghai Pudong Airport which is only a 2-hour high-speed rail ride away. All clients from home and abroad are warmly welcome to book an on-site tour with our sales team in advance, and we also offer live virtual factory tours for anyone who can’t travel.

4. Q: How do you handle quality control across production?A: Quality is our non-negotiable top priority. We run strict, full-process inspections at every stage: raw material incoming verification, in-production dimensional checks, and full performance testing for every finished seal before packaging. Our entire operation is ISO 9001 certified, so every batch you receive meets consistent global industrial standards.

5. Q: What is your standard production lead time?A: Our typical lead time for standard and custom mechanical seal orders is 10–20 working days, counted from the day we confirm receipt of your prepayment. For time-sensitive urgent orders, we can also arrange a priority production schedule upon your special request.

6. Q: What payment methods do you support?A: For small payments like sample shipping fees, we accept both PayPal and T/T (Telegraphic Transfer) for maximum convenience. For formal bulk production orders, our standard term is 100% T/T at sight, and we can negotiate flexible payment terms for long-term cooperative clients.

7. Q: Do you offer OEM and ODM customization services?A: Yes, full OEM and ODM support is available for all our seal product lines. Our in-house engineering team can design and manufacture seals that perfectly match your requirements, whether you provide an existing sample, a full set of technical drawings, or a detailed description of your unique on-site operating conditions.

8. Q: Can I buy complete pumps and other pump spare parts from you?A: Absolutely. Beyond our full mechanical seal portfolio, we also supply a complete range of supporting industrial pumps and related spare parts, including lobe pumps, compound homogeneous pumps, high-shear homogenizing emulsification pumps, and other custom pump components to match your system requirements.
