Dear all,

 

I have case in my water treatment plant. Plant capacity is 4000 m3/h, normal operation we use single pump to transfer water from storage A to C (see drawing attach). and now we want to revamp my transfer water with run parallel pump at A and booster at C. Please give us the best suggestion how to operate that at save condition. The size of pipe line transfer is 28IN Sch STD. Base on manufacture recommendation MCSF of pump is 2000 m3/h.

Dear Ankur,

 

Thanks in advanced for your reply. I have been read those article before. But in many others reference explain that when we run parallel pump total flow not twice flow of each pump but the total flow less than twice of pump (for identical pump). in other hand in my existing plant not install circulation line because in normal operation we always use single pump to transfer water.

 

Have you reference how to simulate my system so that we can give suggestion to my operation division how to operate transfer pump and booster pump safely. in my opinion when we run two pump at 2000 m3/h the total flow my be just 3500 m3/h when we run booster pump parallel too. because when we throttle discharge valve the curve system will be move to the left.

Hi Yani and others ,

there is a very nice free software on internet called PSIM (process system improvement modelling tool) which can support your work . Of course you need to provide necessary information about your system and the pump . Go through the examples provided and then built your own model . It's worth to use it , for better understanding what fluid dynamic is about .

Good luck
