What to specify in your RFQ

Manufacturers quote faster and more accurately when your request covers these points.

  • Seal type and configuration

    Specify whether the seal is a single, double, cartridge, split, balanced, or unbalanced design, including the pump or equipment model.

  • Shaft and housing dimensions

    Provide shaft diameter, stationary-seat dimensions, installation length, and relevant housing or chamber measurements.

  • Operating conditions

    State operating pressure, temperature, shaft speed, fluid type, concentration, viscosity, and presence of solids or abrasives.

  • Face materials

    Specify the required rotating and stationary face materials, such as carbon, silicon carbide, or tungsten carbide, based on the fluid and wear conditions.

  • Elastomer and metal materials

    Define elastomer compatibility and wetted metal requirements, including options such as EPDM, FKM, PTFE, stainless steel, or corrosion-resistant alloys.

  • Standards and certifications

    Identify applicable equipment, industry, hygiene, emissions, or hazardous-area standards and request the corresponding conformity documentation.

  • Quantity and delivery requirements

    State prototype or production quantity, required spares, packaging, delivery location, and target delivery date.

Sourcing FAQ

How should I evaluate a mechanical-seal manufacturer?
Check whether the supplier can demonstrate experience with the relevant pump, fluid, pressure, temperature, and speed conditions. Review material compatibility, test or inspection documentation, replacement support, and ability to meet the required dimensions.
What information should I send with a quote request?
Send the equipment model, shaft and chamber dimensions, existing seal reference, operating conditions, fluid details, materials, applicable standards, quantity, and delivery requirements.
Do mechanical-seal manufacturers have standard MOQs?
MOQ varies by supplier, seal design, customization, and material availability. Ask whether the requirement can be supplied as a single replacement, a small batch, or a recurring production order.
What certifications should I request?
Request only certifications relevant to the application, such as material certificates, conformity documentation, hygienic approvals, emissions compliance, or hazardous-area documentation. The required certifications depend on the equipment, fluid, and installation environment.
What affects mechanical-seal lead time?
Lead time is commonly affected by customization, non-standard dimensions, special face or elastomer materials, testing, certification requirements, and production quantity.
