Thank you guys for all of your valuable inputs,
I double checked with vendor as well,
there is possibility of temperature increase if pumps run for long time on the min flow, as you already mentioned;
So it seems, there is no point for running pump for more than 30' just to have a general...
Thank you all guys for provided responses, flow will be controlled by FCV (flow control valve).
It is not bump test- I am going to do Mechanical Run Test to see pump performance, vibration, temperature, Current etc.
when pump working on min flow (100 m3/hr) discharge of pump would be 100m3/hr...
@ LittleInch
Thanks for your advise, I did MRT for almost the same size pump/ same arrangement on minimum flow for app. 2hrs without any issue, ( I checked pump temperature every 10');
but according to our procedure and client request, MRT should be done in 4hrs, however, as "Artisi" mentioned...
Thank you all for your useful response,
Sorry for delay to response; I had some personal problem:)
Medium is water, constant speed electric, on Flow Control, it is recirculating to the suction pipe and full suction pressure is available- suction pressure is 20 bar .
The reason of testing on...
Normally we are doing 4hrs MRT (mechanical run test) for commissioning of pumps.
Now I have pump, 400Kw- 350m3/hr, (min. flow 100m3/hr)- 50bar discharge pressure and 260m head
any idea for how long can I run it for MRT on minimum flow line to check pump overall performance, vibration, temperature?
