Chromatography pump flow pressure documentation

Pump identification record

Ask the supplier to identify the exact pump addressed by each document. Keep module names and document revisions connected throughout the quotation review.

Use pump identification schedule to connect the wording in the enquiry with the item proposed by the bidder. Ask for a description that identifies the individual item and the product documents attached to it. Keep alternative labels associated with their own questions until your responsible reviewer has assessed the response, and use the agreed item description consistently in the drawing register and purchasing schedule. Ask the bidder to mark any proposed alternative separately so that its description is not mistaken for the item originally requested.

Flow duty statement

Provide the flow duties requested by your method team and identify where each applies. Request a written response addressing those duties individually.

Put the requested application conditions in flow duty worksheet and identify which conditions belong together in the proposed task. Ask the supplier to answer against the particular equipment it proposes rather than a general product family. Request clarification where a statement depends on a different application description, and have your responsible engineer review those conditions alongside the named proposed configuration before equipment selection. Request an explanation of any proposed qualification in the context of the duty it affects, rather than treating it as a general product statement.

Pressure duty statement

Describe the pressure information required for engineering review. Ask the supplier to relate each proposed statement to the relevant operating conditions.

Put the requested application conditions in pressure duty worksheet and identify which conditions belong together in the proposed task. Ask the supplier to answer against the particular equipment it proposes rather than a general product family. Request clarification where a statement depends on a different application description, and have your responsible engineer review those conditions alongside the named proposed configuration before equipment selection. Request an explanation of any proposed qualification in the context of the duty it affects, rather than treating it as a general product statement.

Combined duty clarification

Ask whether the requested flow and pressure conditions are addressed together in the proposed documentation. Request clarification of any separate conditions or qualifications.

Put the requested application conditions in combined duty questionnaire and identify which conditions belong together in the proposed task. Ask the supplier to answer against the particular equipment it proposes rather than a general product family. Request clarification where a statement depends on a different application description, and have your responsible engineer review those conditions alongside the named proposed configuration before equipment selection. Request an explanation of any proposed qualification in the context of the duty it affects, rather than treating it as a general product statement.

Pump document consistency

Compare the named pump across drawings and quotation documents. Return discrepancies as specific written questions before accepting the proposed configuration.

For pump document register, identify the product or equipment item addressed by each requested document. Ask for a document title and the reference needed to connect it with the current proposal. Refer unfamiliar document terminology to the responsible project reviewer, and request clarification where a returned document concerns a different item or configuration from the one described in the purchasing enquiry. Ask the document reviewer to identify which unresolved questions concern missing information and which concern a document referring to the wrong proposed item.

Pump proposal approval

Ask the responsible engineer to approve the answered duty questions. Retain the agreed configuration description with the purchase request for later reference.

Use pump approval brief to separate the questions assigned to each project reviewer and the documents needed to answer them. Connect each open question with the proposed item or stage it affects. Ask for a response addressing those questions individually, and have the responsible reviewer record the agreed description that the purchasing team should use when it prepares the request for commercial terms. Ask the assigned reviewer to distinguish a request for more information from approval of the proposed item, so that open questions remain clear.
