API 676 Compliant Pump with mimimum flowrate
API 676 Compliant Pump with mimimum flowrate
(OP)
I there a minimum flow rate required for a pump to be API 676 compliant.
We are using a transfer pump of flowrate 0.25 LPH of make Wilden, USA.
This pump will be used to transfer Stadis to a tank containing Jet Fuel.
The pump manufacturer has said that this pump follows the guidelines of API 676, but is not complaint to it. But our end user is insisting on a API 676 compliant pump with a flowrate of 0.24 LPH.
Please suggest.

The make of the pump is Viking Pumps, USA. My question remains the same.

There is bound to have some deviation. If your client is concern about the flow rate, he should use a API 675 metering / controlled volume pump. A metering / controlled volume pump allows you to adjust to the exact flow you need and is best for the such low flow rate.

The client wanted to use a transfer pump (for transferring Stadis from one tank to Jet Fuel in another tank).
They also wanted minimal flowrate so that the transfer does not happen quickly (0.25 LPH) and also that this pump should be API 676 compliant.
We gave a Viking Pump with some deviations to API 676.
The pump manufacturer gave us reason that " for a transfer pump to be API 676 compliant, minimum flowrate required is 0.5 LPH "

reason to use API 675 pump. The flow rate can be adjusted very precisely to suit the requirement.

I think I saw a post here awhile back about this practice. It is a shame, but it is becoming all too common in this "cut & paste" world of Engineering. 100% compliance is rarely acheived by any manufacturer for any API pump standard. If someone said they were 100% compliant with API 610, 674,675,676; it would raise large red flags in my mind.
Typically a company will quote a pump and say: We comply with APIXXX with the following "Comments & Exceptions", and then list them out individually according to the paragraph#. It is then up to the Purchaser to decide whether or the points of non-compliance are acceptable or not for that particular service. By the way, API standards are only meant as guides and not the final word on pump construction. Where there is a conflict, the Customer's Data sheet actually takes preference over the API standard.
