Compare hydraulic motor quotes against one defined requirement, including the full configuration, supplied items and delivery basis. In the fictional ten-motor order below, the 185 unit offer reaches 242 per motor after its listed extras; the 210 unit offer reaches 233. The numbers change once the buyer accounts for the complete quoted package.
That exercise uses assumed prices, not a market survey. It shows how to build the comparison: start with an eligible motor configuration, price the required extras, then examine delivery and written terms. Use the tables as a working sheet beside your quotations. An unanswered item stays open until the seller supplies the missing detail.
Start with a revision of the requirement that everybody can identify. For an existing machine, that may be the complete old motor code, a mounting drawing and a short description of the operating duty. For a new build, it may be a specification sheet prepared with the equipment designer. Date the packet and use the same revision for every quotation request.
Read the motor description line before opening the price columns. If it stops at “orbital motor, 200 cc”, ask for the rest of the proposed configuration. The shaft, flange and port arrangement need identifying too. A full nameplate photograph is useful here: the smaller suffix characters can be lost when a code is copied into an email or purchasing spreadsheet.
Manufacturer ordering literature illustrates the difference. The Danfoss OMT/OMV technical information separates motor versions, configuration codes and ordering numbers. Its tables distinguish shaft and connection arrangements within a family. That is evidence for identifying a complete variant, not a cross-reference establishing that another manufacturer's similarly named motor will fit.
The Parker TS ordering information likewise separates displacement, shaft, rotation, mounting/ports and options. For purchasing, the transferable lesson is to attach the proposed code to its applicable drawing and specification. Use each manufacturer's own definitions; copying a suffix from one code system into another can leave the offered construction unclear.
Requirement field | What to put in the request | What the supplier should identify |
|---|---|---|
Product identity | Existing full code or a new-build specification reference | Proposed manufacturer, family and complete configuration |
Mechanical connection | Shaft, flange and relevant installation drawing | Drawing number and revision for the offered arrangement |
Hydraulic connections | Working ports, return/drain arrangement and relevant circuit information | Port specification and any proposed connection changes |
Required operation | Torque, speed and duty; available supply conditions where known | Applicable performance information and unresolved duty questions |
Included functions | Brake, sensor, control or other functions actually required | Which functions are included and which are separate items |
Quantity and destination | Order quantity, delivery location and required availability | Quantity priced, delivery basis and timing assumptions |
Give uncertain entries a status in the request itself. For example, a new machine's operating duty may still need approval from its designer. Suppliers can price a provisional specification, provided everyone can see which requirement was assumed. Once that duty is settled, request confirmation of the proposed build and its price against the approved revision.
An alternative deserves its own entry on the sheet. Put the proposed change beside the requested construction, together with the reviewer responsible for accepting it. A different connection or shaft arrangement may require a new drawing or accessory. Purchasing then has a visible reason for the additional item and a record of the technical decision behind it.
Write out the intended delivery as an item list. Does the receiving team expect one motor, a motor and brake assembly, or a motor accompanied by a connection kit? Which drawings and inspection records should arrive with it? Send that list with the inquiry so suppliers can address the same purchase scope.
Descriptions of the extras need enough detail to place an order. Against “with fittings”, write the agreed connection list or its drawing reference. Against a coupling or mounting kit, identify the part or assembly being priced. This also helps stores check the delivery against the purchase order, without having to interpret a general product photograph.
Scope item | Included | Separately priced | Awaiting clarification |
|---|---|---|---|
Motor in the agreed configuration | Reference the full code | Keep a separate alternate code visible | Offered code or drawing missing |
Brake, sensor or control option | Identify the selected option | Show the item and quantity | Required function not addressed |
Connection or installation kit | Reference the agreed list | Add its confirmed price | “Standard accessories” without a list |
Documentation | State the supplied drawings and records | Identify any additional requirement | A certificate or report is mentioned without scope |
Packing and transport | State the packing and delivery basis | Show each charge and responsibility | Freight or destination unspecified |
Put proposed adaptations through the machine's technical review before including them as an acceptable purchasing option. An additional hose, adapter or coupling can affect the installation as well as the invoice. Record the accepted arrangement so its cost is attached to an approved scope. Paying for an accessory does not establish that the resulting assembly is suitable.
An exclusion can become a separate purchase after clarification. Leave its original status and the dated answer together on the sheet. The extra kit will then appear in the evaluated amount and in the receiving plan, even though it was absent from the supplier's first motor price.
Set up the evaluation columns for a stated quantity and currency. Retain the original quoted amount as well. For offers in different currencies, show the conversion rate with its source and date; the rate used to compare today's offers may differ from the rate available when the invoice is paid.
Give freight quotations a common destination. Specify whether that means a port, your distribution warehouse or the machine site, and attach any receiving restrictions relevant to the shipment. Check the packing, collection and destination charges with the seller and your logistics contact. Customs charges need the responsible specialist's confirmation before the worksheet can be treated as a full landed-cost estimate.
If the offer uses Incoterms, enter the rule, named place or port and version together. The ICC's guide to Incoterms and commercial contracts explains the roles of delivery obligations, costs and risk. It places goods specifications, payment terms and ownership outside the rules' scope. Those entries therefore need their own wording in the order rather than an assumption based on the delivery abbreviation.
Label the source of the additional amounts. The seller's freight figure can go in one column, while your warehouse's unpacking allowance appears as a buyer estimate. An empty freight cell gets “awaiting quote”, not a zero. The evaluated amount remains provisional until that cell has an answer.
Check the addition lines against the included scope. Packing already covered by a package price needs no second allowance. For a transport price covering only part of the journey, add a separate line for the outstanding leg. Keep a brief explanation beside the amount so the next person reviewing the worksheet can trace it.
Consider a constructed example for ten motors. Every amount below is assumed in USD for illustration. These are not market price ranges, BLINCE quotations or offers from identified suppliers. Assume that a technical review has already accepted both complete proposed packages for the same purchasing requirement, including the installation kits. That assumption is necessary before cost can decide between these two offers.
Offer A lists a motor unit price of 185 and excludes several required items. Offer B lists 210 per motor and includes the required installation kits and packing. Both suppliers have provided the freight amounts used here, on the same comparison basis. Use zero only for a charge confirmed as included, rather than for one the supplier has not answered.
Comparison line for ten motors | Hypothetical offer A | Hypothetical offer B |
|---|---|---|
Motor unit price | $185 | $210 |
Motor amount: quantity × unit price | $1,850 | $2,100 |
Required installation kits for the order | $200 | Included: $0 additional |
Protective packing | $60 | Included: $0 additional |
Freight on the agreed comparison basis | $310 | $230 |
Evaluated amount for these listed items | $2,420 | $2,330 |
Evaluated amount per motor | $242 | $233 |
Calculate A as 10 × 185 + 200 + 60 + 310 = 2,420; B as 10 × 210 + 230 = 2,330. For ten units, these amounts work out at 242 and 233 per motor. The 250 difference on the motor line is outweighed by a 340 difference in additional listed charges. B's evaluated amount is consequently 90 lower for the order, or 9 per motor, within the example's agreed scope.
The worksheet stops at the listed acquisition items. Duties, taxes, insurance, payment charges, installation labour and operating costs have not been priced in this exercise. For an actual order, identify the applicable charges and extend both columns to the same cost boundary before deciding which total to use.
Now suppose a third offer quotes 195 per motor but gives no complete configuration or freight amount. It cannot yet enter this cost ranking. Keep its motor subtotal, 1,950 for ten units, visible as a quoted fact. Mark configuration and freight as open. A final evaluated total requires those answers; using $0 for the missing freight would create a misleading comparison.
The example assumes two accepted technical proposals. Should the review reject one, its price stays in the history with the reason for rejection; it no longer competes for the order. The cost calculation cannot resolve a technical rejection, however accurately the buyer has added the lines.
Ask what event starts the quoted lead time. Possible triggers include payment receipt, drawing approval, configuration confirmation or release of a purchase order. Record the actual trigger in the supplier's offer. “Twelve working days” is incomplete for planning when nobody has agreed when the count begins or what is ready at the end.
Ask what the promised date actually describes. A production-complete date can precede packing and document release; dispatch precedes arrival. Write the seller's milestone beside the milestone your project needs, then identify any work or transport between them. This is especially useful when the machine team is planning labour around an expected delivery.
For a hypothetical schedule, allocate approval 3 working days, production 12, packing/dispatch preparation 2 and transit 6. With those stages in sequence, the plan totals 3 + 12 + 2 + 6 = 23 working days. Its twelve-day production entry accounts for only part of the plan. All four durations are assumptions for this illustration, with no actual supplier or BLINCE delivery commitment attached.
Use the actual sequence when stages overlap. Packing preparation may start while production continues, or approval may be finished before order release. Show those dependencies on the plan. Reconcile working-day definitions between the factory and transport estimates as well; otherwise, adding the two numbers produces a duration that neither party has promised.
For a stock offer, request confirmation against the quoted full configuration and quantity. A stock statement for the general family still leaves the actual order to be checked. If some units are available earlier, ask for a shipment schedule showing quantities and charges for each release. The buyer can then see whether the first delivery covers the immediate need and what the later balance will cost to receive.
Look at what accompanies a phrase such as “factory tested”. There should be a way to identify the motor or lot, the test performed and its acceptance basis. A company certificate addresses another question, with a holder and scope of its own. Put each document beside the claim it is being used to support.
On a dimensional report, follow the drawing reference through to the features measured and their acceptance criteria. For a functional result, look for the tested configuration and conditions, then check whether the coverage is one sample, a batch or each delivered unit. A test-stand photograph leaves those order-specific questions open. Ask for the relevant record if that evidence is needed for approval.
Evidence item | Question it can help answer | Detail to request |
|---|---|---|
Configuration drawing | What construction is being supplied? | Offered code, dimensions, interfaces and revision |
Dimensional inspection | Was the specified interface checked? | Features measured, tolerances and applicable product identity |
Functional test record | What was checked under stated conditions? | Test conditions, acceptance limits and unit/batch coverage |
Traceability information | Can the delivered item be linked to its records? | Model, serial or batch reference, as applicable |
Certificate | What organization or activity is covered? | Holder, scope, issuing body and validity |
Specify the document packet with the inquiry. Reordering an established configuration and qualifying a new supply source can require different approval work. The supplier needs to know which work is included in this purchase before pricing it. Additional inspection requested during final negotiations should have an identified cost and schedule effect, even when the parties agree there is no extra charge.
Where the evidence is pending, name the missing report or condition. Keep any assessment of reliability separate from that document status; a more complete quotation is not a measurement of longer service life.
For a sample, write down the question it will answer. The evaluation might concern the interface, specified performance or an agreed inspection procedure. Identify the sample build and the intended production build on the same review. If either changes, revisit the affected approval; keep the production-lot acceptance procedure attached to the later order.
Read the written warranty with the offer to which it applies. Identify the start event as well as the duration, the claim contact and the stated remedy. The buyer also needs the assessment and return procedure. Put unanswered questions about transport, labour or other costs in the commercial review, with the supplier's eventual clarification beside them.
Check the costs around a replacement separately: removal and fitting, technician travel and any claimed lost production. Their treatment depends on the actual agreement. Refer unresolved wording to the appropriate commercial reviewer before accepting the order; the comparison sheet should state the terms obtained rather than supply its own interpretation.
Turn a support requirement into a defined request. If you need someone to review the installation drawing, say so; if the machine requires on-site commissioning assistance, specify that separately. Name the contact channel and obtain the service scope in writing. A promised response time is useful only when the parties have identified the request it covers.
Apply that review to both original-brand and alternative-source offers. Identify who sells the motor and whose warranty is being supplied. Where a distributor adds a service of its own, show it separately from the manufacturer's terms. This lets the buyer compare the commitments attached to the actual quotations rather than assume a service package from a logo.
Retain return or exchange instructions with the named claim contact, including any approval needed before shipping a unit back. Follow the agreed assessment process rather than treating a clear procedure as a promise that any claim will be accepted.
Set out the immediate requirement beside each quantity being offered. A larger order can spread a fixed charge across more motors while leaving more units in stores. Break out one-time charges, packing and shipment costs so the buyer can see what changes with order quantity and what will recur on the next release.
In the ten-motor example, dividing order freight by ten is appropriate for that assumed ten-unit shipment. It would not establish the freight per unit for a later two-unit order. Request a separate quotation for the smaller quantity if it is part of the buying plan. Do the same for spare kits, additional documentation or special packing that may be ordered separately later.
Read the conditions attached to a price break. For an order containing several configurations, establish whether the qualifying quantity is per configuration or for the whole order. Ask for the minimum order quantity and validity with each offer; apply the supplier's stated terms rather than a general assumption about volume discounts.
For a repeat purchase, retain the accepted complete configuration and its drawing revision. Reference them in the next request, then have the supplier identify any proposed change. A family label in an old invoice can be too broad to reproduce a previous build. A change to the shaft, connection arrangement, option or included documentation should be visible before the repeat order is accepted.
If standardizing the stock list would change a motor configuration, obtain the technical decision for the affected machines first. The purchasing review can then compare the approved stock options and their quoted quantities.
At the top of the decision sheet, put the requirement revision. Against each offer, add supplier, quotation number, date, revision and validity. Link its full proposed code to the relevant drawing. The original price and the buyer's evaluated amount occupy separate columns, so the additions remain visible to the person approving the purchase.
Use a few defined labels for line items: “confirmed included”, “confirmed extra”, “not required” and “awaiting clarification”. Give the whole offer a status too. An offer still undergoing technical review occupies a different stage from an accepted configuration with all purchasing costs resolved. A blank cell communicates neither stage reliably.
Decision-sheet field | Record against each offer |
|---|---|
Requirement and offer identity | Request revision, quotation number/date, supplier and proposed full code |
Technical status | Accepted scope, stated deviations and responsible reviewer |
Cost basis | Quantity, currency, conversion basis if used, included items and separately priced items |
Delivery status | Start trigger, promised milestone, transport basis and required availability |
Evidence and support | Documents included, inspection/test scope and applicable written terms |
Open items | Exact question, owner, requested answer date and effect on the decision |
Assign each open item to the decision it affects. The port specification goes to the technical reviewer, the outstanding freight amount to the cost comparison and the lead-time trigger to the schedule review. This gives the team an owner for each answer and makes the reason for a pending decision visible.
Send a compact clarification request that references the offer and its unanswered items. For example: confirm the proposed full code and drawing revision; identify whether the listed kit is included; price freight to the stated destination; confirm the lead-time start event and ready milestone. Retain the answer with the original offer and update the comparison with its date.
A revised price needs a revised-scope check. Compare the new configuration, quantity, document list and delivery basis with the previous offer before updating the amount. Retain the earlier quotation and note the changed lines. The person approving the purchase can then see whether the negotiation changed only price or also what will arrive.
The evaluated purchase amount is one part of ownership cost. Parker's construction-equipment TCO material identifies purchase, installation, operation, maintenance and downtime as cost considerations. Use that broader view to decide what additional evidence the machine project needs. The source does not provide a measured saving for a BLINCE motor or a universal percentage split for every hydraulic application.
If energy consumption, service intervals or downtime are material to a choice, use applicable product data, site records or clearly identified assumptions. A supplier's lower unit price does not establish its operating cost, and a higher price does not establish longer life. Keep the supporting evidence beside each lifecycle input rather than allowing a price difference to stand in for a reliability test.
For a simple hypothetical downtime sensitivity, suppose an otherwise acceptable option costs 90 more for the complete ten-unit acquisition scope. If the buyer assumes an avoidable downtime cost of 180 per hour, 90 ÷ 180 per hour = 0.5 hour, or 30 minutes. This calculation describes how much downtime value would equal the assumed purchase difference. It does not predict that either offer will prevent a failure or save that time.
Use a different result if the site's downtime assumption changes. Include only the cost categories relevant to the actual decision and avoid adding the same lost-production amount in several places. Where the project lacks reliable operating or failure data, show a range of assumptions or leave the estimate unresolved. A visible uncertainty gives the decision-maker more information than an unsupported payback claim.
If this purchase follows a failure, retain the outstanding cause investigation with the machine records. Accepting a supplier's offer establishes a supply decision; it does not settle what caused the previous failure.
Use the BLINCE hydraulic motor category to identify the family you would like to discuss. If you already have a replacement requirement, attach the complete existing model code and the relevant installation information. For a new build, send the requirement sheet that your team is using to compare offers.
Include the order quantity, destination, required availability and the components or records you want included in the quotation. Mark any alternate construction, drawing or commercial term that you are prepared to consider. This lets the discussion focus on the actual package you need rather than a unit price with its scope still undefined.
For a useful first inquiry, provide:
Existing full model code or proposed motor family, with a readable nameplate photograph where available.
Mounting, shaft and connection information, plus relevant duty and supply conditions already known.
Quantity, destination and required availability.
Included functions, installation items and documentation needed for the purchase.
A short list of details still to be confirmed by the supplier or your technical reviewer.
Send the packet through the BLINCE contact page and request an offer that identifies the proposed configuration, included scope, exclusions and commercial conditions. Keep any unresolved item visible on your comparison sheet until its written answer is available.
