Pump Max Pressure and Max Head

[nabeel3]

Dear All
I am using a pump with the following Data sheet and Pump curve.

When I asked the following question to the Vendor
"From datasheet the Max Pump pressure is given as 25 bar. As per the Pump curve, the max pressure is 8 bar approximately. Can u please clarify"

His reply is as below
"Max delivery pressure is the pump design pressure"

I couldn't understand the difference. Can the experts help me please here.

What he means is that the pump casing has a design pressure of 25 bar.

Depending on the inlet pressure the outlet pressure is the inlet pressure plus 8 bar (at no flow).

what is your inlet pressure?

but vendors tend to just make one casing and then insert all sorts of different impellors. This one uses a casing with a DP of 25 bar.

does that help?
