Seal-face damage, deposits, or loss of lubrication
Evidence to capture
Capture fluid composition, vapor behavior, solids, chamber pressure, temperature cycle, flush plan, and face condition before cleaning.
Application engineering
Chemical & Petrochemical Mechanical Seals & Parts
Mechanical seals and corrosion-service components selected around process fluid, temperature, pressure, solids, emissions, and maintenance objectives.
Failure evidence
Common failure patterns—and what to document first
A failed sample shows the result, not necessarily the cause. Preserve the operating history and as-found condition so the replacement review does not reproduce the same assumptions.
Localized corrosion or rapid material loss
Evidence to capture
Record concentration, contaminants, aeration, velocity, temperature excursions, actual alloy evidence, and the location and shape of the attack.
Agitator leakage after shaft movement or cleaning
Evidence to capture
Check shaft runout and axial movement, vessel pressure or vacuum, cleaning media, mounting geometry, and the existing seal arrangement.
Selection scope
Components matched to the actual duty
The items below are starting points for an RFQ. Final material, geometry, inspection, and documentation are confirmed against the equipment data and purchase specification.
| Component | Selection basis |
|---|---|
| Chemical Pump Mechanical Seals | Face and elastomer combinations selected from the stated fluid and duty |
| Agitator & Reactor Seals | Seal arrangement reviewed for vessel pressure, shaft movement, and process conditions |
| Pump Shafts, Impellers & Casings | Stainless, duplex, cast iron, nickel alloy, or specified grades subject to review |
| Valves, Fittings & Flanges | Material and pressure class matched to the project specification |

Buyer questions
Chemical & Petrochemical sourcing FAQ
What information is needed for a chemical & petrochemical component inquiry?
Send the equipment make and model, drawing or sample details, material requirement, operating conditions, quantity, inspection scope, and delivery destination. For a mechanical seal, also include shaft size, fluid, pressure, temperature, and speed.
Can you review a failed or obsolete part?
Yes. A usable sample, dimensional records, material reports, equipment manual, and service history can support a technical review. The quotation identifies which dimensions, materials, and performance assumptions still require customer confirmation.
Which inspection documents can be included?
Documentation is agreed before production and may include material certificates, dimensional reports, hardness results, NDT reports, pressure-test records, or other project-specific records when applicable.
