Gents!
After complete inspection, the first thing we notice is the impeller chipped significantly.
this is due to defective MGPS system which allow shells alike went inside the system and .... it's like sand blasted.
Not only the pump, but all the valve is also affected.
Cheers,
ColSander / rmw,
Thanks for the tip and advise regardless of what material or standard both of you refered to.
And since my vessel used a hug amount of bellow, metal or non metal metarial, i really need some guideline as to speed up my construction.
thanks

Thanks JJpellin,
Artisi,
it's a normal 4x3x13 horizontal centrifugal pump.
hydraulic problem ==> i don't think so, due to independant seachest suction.
anyway, just give order to inspect the pump impeller and do the balancing check. crossing my finger
Thanks Artisi for your advise.
Below is the answer for question you ask;
Is this something that has "just" happened or has it been a gradual build-up.
==> gradually build up, i believed. i've done workshop testing befor we installed and nothing wrong with that pump.
Is there any noise...
Guys!
Just trying to figure out about the vibration on one of the installation onboard.
the alligment between motor and pump, pump and pipes is ok.
the foundation is up to standard. all stiffners are in order. Still, i have quite significant vibration.
i haven't open up th e pump yet to...
Gents!
Need some advise on the tolerance between rubber expansion bellow and pipes.
The alignment on the pump discharge is ok but the alignment on pipe side read 4mm diferences.
so, the question is, how much allowable tolerance for the said bellow with pipe, and what standard which i could...
Thanks Morten,
is there any way to overcome this problem without changing the pump?
I'm thinking to add more plate cooler as to increase the effeciency of heat tranfer rate.
any advise?
Assuming I have a pump which supplied water to PHE (cold-side) at 50m3/hr.
what happen if the supply of water is decrease since i'm want to tap that line for other services?
I'm doing a project wich required me to calculate the transfer rate of Barite & Cement from tanks to tanks. I've run couple of calculation but i'm not sure it is the correct one or not.
the detail is as follow;
Pipe size = 5" / lenght of pipe (approx. 100 ft)
eductor = 1" c/w fluffer vlv
acfm...
