Hello,
our plant will revamp super high BFW system, and need add a new BFW feed pump. At present, there are three pumps in this system, one is motor drived,two are drived by turbine. normally, two run, one standby. Normal flow of every pump is 170M3/h, and the dischaige pressure is 15Mpa, the temperature is 120. now , the problem is we can not find a duplicate to existing pump and we add a different pump will bring what result, whether it will cause unstable or other situations? the textbook said it is not recommendated two different pumps work together. in addition , I aslo consult some power plant engineers , they also held same opinions , BFW feed pumps in most of PP are produced by same manufacturer.
So, I would like to seek some expert to clear my confusion and give some comments for this matter.
