Submit the paired duty request
Provide the requested flow and head together for each operating scenario and identify the corresponding project route. Attach the available record behind that requirement and distinguish project inputs from existing observations. Ask the supplier to identify which operating case its proposed configuration addresses before requesting the corresponding performance curve for buyer technical review.
Keep additional cases in separate worksheet rows. Identify the slurry description belonging to each case and ask which rows remain unanswered. Request a revised curve response when the project team changes the route or operating requirement, keeping the case labels visible so the returned document can be compared with the intended duty rather than an earlier project condition.
Identify the proposed configuration
Ask for the pump configuration reference associated with the curve and the item description used in the quotation. Request the configuration information needed by the buyer reviewer to identify the proposed assembly. Ask for clarification where the designation on the curve differs from the designation in the equipment schedule or other documents returned with the supplier response.
Keep curves for alternative configurations separated under their own identifiers. Ask the supplier to state which configuration belongs to the main quotation and which is an option. Request revised attachments if the proposed assembly changes, and check that the curve reference remains connected to the same item across the quotation and technical documents used in the purchase comparison.
Request the curve conditions
Ask for the test or stated conditions associated with the returned performance document and identify its revision. Request an explanation of the terminology used where the buyer cannot trace it to the document. Keep the conditions attached to the curve rather than copying a graphical result into the purchasing worksheet without its corresponding context and configuration reference.
Ask which submitted slurry and operating case the supplier has used in its response. Request clarification if the curve conditions differ from the buyer duty description. Refer the returned information to the project specialist for review, and ask for missing condition documents before treating the curve as an answer to the particular equipment selection question raised in the enquiry.
Locate the requested operating point
Ask the supplier to identify where its curve response addresses the paired operating point submitted by the project team. Request an annotation or written document reference that connects the response with the correct duty worksheet row. Keep normal operation and other requested scenarios separately identified so the buyer can see which cases have been answered by the proposed configuration.
Ask for clarification where the curve response addresses another operating condition or only part of the requested schedule. Request a separate answer for an alternative configuration rather than combining its curve with the main proposal. Refer questions about the returned operating point to the buyer technical reviewer before using the document to approve the proposed equipment for purchase discussion.
Match the surrounding technical documents
Collect the curve, configuration description, slurry record and route drawing under the same proposed equipment reference. Ask for the corresponding drive and assembly information needed by the project reviewer. Request clarification where another attachment describes a different item, and keep any optional arrangement separated from the main equipment scope so the document set can be reviewed consistently.
Ask which additional project information the supplier needs to address an unresolved duty case. Record changes to the requirement in the duty worksheet rather than leaving them only in correspondence. Request a revised response when those changes affect the proposed configuration, and retain the earlier curve separately so the project can identify the current document used for comparison.
Close the curve request questions
Ask the project specialist to review the returned curve and conditions against the paired duty requirement. Request written answers to unanswered configuration or operating case questions before approving the proposed equipment schedule. Ask the supplier to carry the agreed curve reference and equipment identifier into the quotation attachment so the purchasing discussion uses the same technical response as the buyer review.
Request the remaining installation and maintenance documents as separate items in the equipment enquiry. Keep commercial confirmation of the supply scope with purchasing. Confirm minimum order quantity and lead time before ordering, and request packing and delivery terms for the specific proposed package rather than treating receipt of a curve as confirmation of the complete equipment purchase arrangement.
