When to request mechanical run test for API 610 pump
When to request mechanical run test for API 610 pump
(OP)
Hi everybody,
How are you?
I have to decide if mechnical run test is needed for some small API pumps. Could you please give me any hints on it? Thank you.
All the best,

Pump testing is all a matter of policy and cost. "Mission critical" and large expensive pumps are the types that tend to be tested in the shop.
The most common tests are:
1) Casing Hydrotest
2) Running (performance) test
3) NPSH test
It is my experience that #1 is always requested, and it is common for most pump vendors to hydrotest all casings for all pumps.
The run test is somewhat expensive, can delay delivery significantly and, in my opinion isnot required for all pumps. Some process chemical companies have guidleines about "run testing" for pumps that operate above a certain temperature (250-300F)or a certain fluid service (high vapor pressure liquids or liquids that have caused problems in the past)
It is all a matter of judgement..
The NPSH test, as I understand, is very expensive and can delay delivery significantly. NPSH testing requires a looped test rig with a lot of sensitive instruments. The onset of cavitation is defined by HI standards.
Smaller ANSI and API pumps typically only have #1 testing.
My opinion & recollections only.

What brand of API pumps do you sell and are your (ease of testing)claims the same as your competitors ?
I admit that most of my experience has been with smaller ANSI B73.1 series pumps, where the capital cost of the pump is modest and the testing adds significantly to the cost.
Again, this is all a matter of policy, schedule and cost.
