Equipment OEMs
Build-to-print parts, mechanical seals, and coordinated documentation for repeat supply.
About meilongmfg.com
An engineering-led path from RFQ to industrial supply
We help overseas buyers specify, source, inspect, and receive mechanical seals and drawing-controlled industrial components from China.
What we do
Two focused supply programs
The first is mechanical seals: cartridge, component, metal bellows, agitator and reactor, OEM-compatible replacement, and related support systems. The second is custom industrial parts produced from drawings, models, specifications, or qualified samples.
Our role is to turn incomplete purchasing information into a reviewable manufacturing scope—clarifying duty, material, dimensions, inspection records, packing, and delivery expectations before the order is released.
Who we support
International equipment manufacturers, industrial distributors, maintenance teams, and project procurement organizations.
Distributors
Cross-reference and supply-program discussions supported by samples, codes, and target markets.
MRO & repair teams
Replacement review from pump models, failed parts, measurements, and service conditions.
Project buyers
Commercial and technical review against the project specification and inspection plan.
Application engineering
Meet Jack Ni
Chief Application Engineering Consultant
Jack supports the technical review behind our mechanical seal, replacement-part, and process-equipment inquiries. Trained in chemical process machinery, his work connects field symptoms and operating data with equipment geometry, materials, sealing conditions, inspection needs, and practical modification options.
His focus is to turn an incomplete problem statement—leakage, vibration, wear, corrosion, recurring failure, or an obsolete component—into a clearer engineering review before a supply route is proposed.

How we work
Evidence before promises
- 01
Define the requirement
We review the drawing, seal code, pump data, service conditions, quantity, destination, and required records.
- 02
Resolve technical gaps
Open questions and manufacturability concerns are documented before price and lead time are confirmed.
- 03
Agree the quality plan
Material records, dimensions, testing, marking, preservation, and packing are matched to the order.
- 04
Support repeat purchasing
Approved references and clarified specifications create a cleaner basis for future orders.
Start with the information you already have
A pump model, drawing, data sheet, seal code, or usable sample is enough to begin a scoped technical conversation.
Long-tail buying intent
Industrial supply partner searches
These search phrases describe common variations of the same buying requirement. Final selection still depends on the drawing, equipment, duty, and order scope.
