Double Bellows Mechanical Seals
Double Bellows Mechanical Seals from Wesson Bellowtek Ltd. are engineered for dynamic sealing in rotating equipment, featuring dual metallic bellows to accommodate axial movement and thermal expansion. The JMT1701 model conforms to ISO 3069 and DIN 24960 dimensional standards, with contact faces typically made of silicon carbide or tungsten carbide, and elastomers in FKM or EPDM for chemical compatibility. These seals are designed for use in pumps, agitators, and mixers handling aggressive fluids under pressure.
The bellows are fabricated from 316L stainless steel or Hastelloy C-276, selected based on operating temperature and media corrosivity. Typical face widths range from 6 to 12 mm, with axial compensation of 3 to 8 mm. Spring-loaded designs ensure consistent contact pressure, while secondary seals use V-rings or O-rings rated for temperatures from -40°C to 200°C. These seals are not intended for dry running and require adequate lubrication from the pumped fluid.
End users include chemical processing plants, pharmaceutical manufacturers, and wastewater treatment facilities that require leak-free operation in high-pressure or high-temperature environments. Orders are typically fulfilled in batches of 10 to 50 units, packaged in protective foam-lined boxes with individual serial tagging. Trade terms are commonly FOB Hangzhou Port, with lead times of 4 to 6 weeks after deposit confirmation.

Wesson Bellowtek Ltd. is based in Hangzhou, Zhejiang, with manufacturing facilities at 4/f, Building 1, No.8 Jianghui Rd, Binjiang District. The company is registered as a manufacturer of mechanical seals and has verified business registration with Chinese commercial authorities. It does not publish certifications such as ISO 9001 or API 682 compliance, nor does it disclose annual production volume or client list.
The supplier responds to inquiries through platform messaging but has no recorded response rate or average response time. Its product focus is limited to bellows-type mechanical seals, with no evidence of offering gaskets, valves, or ancillary components. The absence of third-party audit reports or export history details suggests a niche, production-driven operation rather than a full-service distributor.

Sourcing Double Bellows Mechanical Seals from Wesson Bellowtek Ltd. - China Import Guide
Before ordering, verify the seal material composition matches your process fluid. Request material certificates for bellows and faces, especially if handling acids, solvents, or high-temperature steam. Confirm the elastomer is compatible with your media using chemical resistance charts. Do not assume standard materials are sufficient without testing.
Confirm lead time with the supplier, as custom configurations may extend delivery beyond 6 weeks. Standard terms are FOB Hangzhou Port with 30% advance payment. Payment via LC is common for first-time buyers. Ask for a packing list detailing serial numbers and inspection tags. Incoterms 2020 should be specified in writing.
Perform a visual inspection upon receipt for surface scratches, bellows deformation, or missing components. Check that face finishes are smooth and free of machining marks. Request a test report showing hydrostatic pressure testing at 1.5x operating pressure. Retain samples for third-party lab analysis if critical to your operations.
