Reciprocating Pumps
Reciprocating Pumps
(OP)
Hello everybody,
I have very little experience in technical bid evaluation for reciprocating pumps.
I tried to arrange a tabulation sheet based on the requirements of API 674, but it's very difficult since there are a lot of parameters to be consider.
Based on your experience, could you help me?
Thanks in advance
Regards

RE: Reciprocating Pumps
thank you very much for sending the API 674 data sheet.
It's the first time that I have to prepare the RFQ for purchasing of Reciprocating Pumps. I'll begin to fill in the pump data sheet.
In any case, what are the main parameters to be consider in order to assess properly the vendors' bids?
Thanks in advance
Regards

Also: There's usually a good reason why everyone does it that way
RE: Reciprocating Pumps
please see here attacched a copy of tecnical bid evaluation that I usually submit with RFQ to vendors for purchasing of screw pump.
I'm trying to get the same for reciprocating pump.
What do you think about my way of working?
Thanks in advance for your cooperation
Regards
RE: Reciprocating Pumps
It's a strategy I have used and I like the idea. The only thing I would say is that, if that is what you tell them you will be using as the basis for evaluation, then evaluate fairly on exactly that basis. Don't blindside them by evaluating them on stuff you haven't foreshadowed, because that's not fair.
RE: Reciprocating Pumps
The best thing you can do is to use the API674 data sheet posted by "mcalbrch" above. If there are areas of the data sheet that are difficult for you, then either go learn about them or get someone else to do the evaluation. With all due respect, your evaluation sheet will be a disaster trying to differentiate between reciprocating pumps.

RE: Reciprocating Pumps
there is a misunderstanding.
I usually submit to the supplier the following documents:
- the supply specification with the attachements, including the API data sheet filled in, painting spec's, etc.
- the material requisition
The problem is that the most of pump suppliers don't give me back the data sheet filled in along with the BID, so I have to ask them to provide all data necessary for technical evaluation.
They usually reply me that they will fill in the data sheet only after purchase order, so I have thought to submit them the technical bid evaluation form in order to have the main characteristic from the pump suppliers.
If I understand correctly, the best way it's to oblige the supplier to fill in the pump data sheet with relevant data.
I'm sorry to trouble you but I'm a new graduate and I'm learning.
Thank you very much for your cooperation.
RE: Reciprocating Pumps
Of course, not every line in every API 674 data sheet is meaningful for EVERY reciprocating pump. But it is not tough for a supplier to note "Not/Applicable" on that line, and be ready to explain the ommission to you.
Are you actually dealing with the Pump manufacturer, or a distributor/representative of the manufacturer?? I cannot imagine a reputable manufacturer not jumping at the chance to fill out the data sheets at least. If you are dealing with a distributor or a rep, call the manufacturer and tell them what's happening.
Do not consider buying one of these pumps before seeing it's performance data. And the API data sheet will have 95% of the data you need to purchase.

Beleive me, DubMac, if you do that work a few times for the same (possible) client, especially if he is not the end user, and you never got a PO, you'll question if all that preliminary work makes sense.
RE: Reciprocating Pumps
in my little experience, I can confirm that in the bid stage it's difficult to have all the information from suppliers, since they are not confident to take the Purchase Order, while after P.O. they give all the information requested.
I noted that they usually limit themselves to give the basic information according to their standard procedure.
Thank you very much for your cooperation.

RE: Reciprocating Pumps
Well, that's what I did here. One of a requirement on gov't regulation on procurement and tender, so we can't run away. But it does make all the suppliers comply to your requirement/wish.

RE: Reciprocating Pumps
you're absolutely right and I agree with you. For your info I work in Italy and the most of suppliers are Italian, I have noted that the other suppliers (like american, english) are more precise.

The only way it's to arrange a pre-bid meeting, but many times it's difficult to find time since I'm very busy and it's difficult to follow a lot of equipments
Thank you very much and sorry for my english
RE: Reciprocating Pumps
DubMac: The world was Europe (too). But we never cashed the check after PO but after shipment. Advanced payment is not common here. But my salary had to be paid by someboby. You know how long it takes to fill data sheets and how stupid some requirements are, especially if a standard data sheet is sent which has nothing to do with the content of the inquiry. Why did somebody need to know what brand our crankshaft bearings were? If that was important (perhaps because the client prefered a special brand), they should mention it in the inquiry. Then is is an important criteria. Otherwise I had to submit design details for nothing. I must tell you that I was talking about bids to OEMs, distributors etc. - no about bids to end users because with them I could talk.

nclbrg: Yes, and because you do not find the time the vendors should spend more time with uncertain result of their work. That's what I meant. Don't take it personally!
RE: Reciprocating Pumps
If a client tells a vendor which MFGR's bearings to use, the vendor is more likely to charge extra for a custom bearing order. If he asks and you just happen to supply one of his approved MFGR's bearings, he guts it for no extra charge.
