Mechanical Seal Sourcing terms of service

These terms cover use of Mechanical Seal Sourcing pages and inquiry forms. They do not create a manufacturing warranty, a brand-appointed reseller appointment or a commissioning result that this service can certify.

Independent sourcing role

Mechanical Seal Sourcing is an independent sourcing partner. We coordinate mechanical seal inquiries and factory quote requests. Supplier identity, process feasibility, sample terms and shipment statements are those of the named supplier in each reply. No page should be read as original-equipment identity or as factory ownership by this service.

Inquiries and documents

Buyers are responsible for the accuracy of chamber drawings, fluids, quantities, destinations and delivery windows. Drawings sent after an inquiry remain the buyer’s material; this form does not host uploads. We may ask suppliers to restate shaft dimensions, face materials, working pressure with units, flush or quench plan, tooling, installation and spare parts before a comparison is useful.

Quotes and orders

Factory quotes are requested for comparison. Validity, Incoterms, packing and taxes must appear in the supplier document. This service does not publish savings percentages or claimed warehouse stock. Any purchase contract is between the buyer and the chosen supplier unless a separate written appointment says otherwise. FAT and SAT obligations follow that contract.

Acceptable use

Do not use the inquiry form to request unsafe unguarded equipment or to misrepresent destination or end use. We may decline to forward such requests. Complete pumps, mixers and unrelated machinery families are outside this site’s procurement cluster unless you open a separate brief.

Product changeover questions

What changes between products?

Face pair, elastomer, gland bolt pattern and flush or quench connections often change when the fluid, solids or working pressure change, even if the shaft diameter looks familiar.

What must be cleaned or replaced?

Ask bidders to mark whether the sleeve, mating ring, gland plate, springs and support-system piping are in the same line as the rotating assembly or quoted later.

How is the first good output verified?

Record leak-off, flush flow and chamber temperature against the named pressure reference during the sample run; do not treat a dry spin as SAT.

Preference describes documentation depth, material traceability and support-system completeness. It is not a verified supplier rating, and you do not need an existing quote.

Include seal type (cartridge, multiple-spring pusher or elastomer bellows); shaft, sleeve and seal-chamber dimensions; fluid composition, viscosity, solids and cleaning fluids; normal and upset temperature; working pressure with the gauge or absolute reference; surface speed or rotational speed plus diameter; required flush or quench plan; quantity; destination; delivery window; FAT/SAT and spare parts expectations; optional budget with currency and per-unit or whole-order basis; optional supplier preference (high-end, mid-range, budget or undecided). Drawings can be sent after we reply; this form has no upload field.

Add specification, quantity, destination and timing before sending.
