Hello.

I'm working refinery revamping PJ.

I received existing pump datasheets from Company and I found a term "AMPLE".

Some pump datasheets specifies NPSH available as "AMPLE" instead of certain value.

I would like to know exact meaning of AMPLE and how should I understand this.

Thanks a lot.

Poet,

 

It means: "More Than Enough"...hence wherever the NPSHA is specified as "Ample", doesn't need to be specified with a value and the pump's NPSHR would be adequately lower than the NPSHA...

Hi,

 

I have seen ample specified in the datasheets for Vertical and Submersible Pump pumping sub cooled liquid.

 

These pumps can have low NPSHR hence at times AMPLE is specified in the datasheet.
