(OP)
hi,
Is 15m of pump's head mean discharge preesure will be higher than the suction pressure with that value.

thanks.

RE: is 15m means inlet/oulet press.difference?

Your question is not really clear in what you are trying to find out - can you restate it so that we can assist you.

At the moment, my understanding of your question is, if you have a positive suction pressure and the pump is capable of adding an additional 15 metres - then the total discharge head will be 15m + the suction pressure.

RE: is 15m means inlet/oulet press.difference?

yes, it means :
Discharge Pressure (Pa)= Suction  Pressure(Pa) +
(Rho(Kg/m3)*9.81*15)

For water Rho is 1000 Kg/m3.

RE: is 15m means inlet/oulet press.difference?

roughly yes, but you must take into consideration:

1-kinematic energy diference at inlet/outlet
2-hydraulic losses between measurement points, other than those between inlet and outlet pump flange.
