Is it possible to carry out MRT by water service. Or we shall wait and perform it with Naphtha service ???
Is there any criteria of service density range allowing water MRT ???

Hi ,
I believe the hydraulic tests of your pumps ( TDH vs Flowrate ) were performed using water . Check the documents that were supplied together with the pumps .
Density is affecting the power consumption .
hope this is helping you .

Hello, i am currently commissioning Naphtha hydrotreating unit and i need help regarding Naphtha Pumps mechanical run test (MRT).
Is it possible to carry out MRT by water service. Or we shall wait and perform it with Naphtha service ???
Is there any criteria of service density range allowing water MRT ???
Hi,
In your case the MRT can be done by water...

What about vibration and temperature ? Would not be high due to water high density (naphtha actual density at some pumps are 550-650 kg/m3)
I think, even if higher density would lead to vibration increment, the vibration level of the test with water should be within the allowable vibration range because almost all pumps should be designed to handle the water without any problem...

Did you ask your pump vendor?
