@compguy22 : Thank you for your response.
Based on your experience, how detrimental can the reliability of low-power fans (<50 kW) running at the left of the surge point be? Specifically for combustion air fan applications.
@SB1976 : Thank you for your response.
a) In point 1, you have mentioned " As such, for low power centrifugal fans, there is hardly any temperature rise and hence surge is not a very critical issue.": Can it be inferred that low-power fans can be operated at the left of the surge point without...
Can anyone provide clarity in understanding:
maximum dynamic sealing pressure (MDSP) ( Barrier over Process)
maximum dynamic sealing pressure (MDSP) (Process over Barrier)
maximum static sealing pressure (MSSP)( Barrier over Process)

@pierreick: Thank you for the response. Acronym reference updated in the original query.
I understand it is the client's responsibility on deciding the operational philosophy.
My query is regarding, how the vendor is selecting the pump. ie we can have access to the selection program of M/s...

@LittleInch: Thank you for the response.
However for low kW pumps (<20kW), as per my understanding, it is economical to go with the orifice.
Also, my query was regarding pump selection, in vendors' software. Since MCSF changes with Rated flow, how do finalize a pump model? (Since it can lead...
As per my understanding pump vendors size centrifugal pumps (consider an API 610, OH2) for the rated flow(Rf). However, if the MCSF flow is through an orifice, this flow needs to be added to the rated flow, and the new flow (Initial rated flow + MCSF) becomes the rated flow (New rated flow...
