Raw Water Pumps-API or non API

[tiputyper]

Hi all Experts,
Currently i am preparing a mechanical data sheet for raw water pumps.I am a bit confused whether to specify API 610 or Non-API/Manufacturer's Standard as the governing code.Kindly advise.

Thanks in advance.

Per the API standard, pumps meeting the API standard are appropriate and cost effective for pumps when pumping liquids at conditions exceeding any one of the following:

Discharge pressure (gauge): 1 900 kPa (275 psi; 19,0 bar)
Suction pressure (gauge): 500 kPa (75 psi; 5,0 bar)
Pumping temperature 150 Degrees C (300 Degrees F)
Rotative speed: 3,600 r/min
Rated total head: 120 m (400 ft)
Impeller diameter, overhung pumps: 330 mm (13 in)

Most raw water pumps are not used in such demanding applications. Most pumps used for this application are not API standard unless there is a specific client request.

See the attached API page.

API is a standard with intent towards pumping hydrocarbons safely and reliably. It use has been stretched incredibly beyond it's original intent; especially by engineers trying to cover their butts.

With all due respect, and not personally directed at you, but would be ridiculous to consider API 610 for you raw water service.

What are your Conditions of Service, and what type of facility is it in?

API610 for a raw water pump is excessive. Other codes or mentalities standards are available.

Try looking up AWWA or threads like

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

Would have to agree with DubMac, completely over the top for a water application, usually specified by people who wouldn't known their arse from their elbow.

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

Non API, maybe per Hydraulic Institute. But if you are just deciding between two boxes to check, then the answer is Non-API/Manufacturer's Standard.
