Pumping leg - is it possible to be described in other words? Need it for translation purposes.
It is from specification of lean amine pumps: differential pressure =n, including 3.3 m pumping leg.
Thank you in advance

I do not know what you mean by pump leg. That is not a term that I am familiar with. Please explain.

Wrong part of the body. Not "leg". 3.3 meters of pump "head" works for me. :)

That much pump head doesn't sound like a very serious pump to me. However, if it referred to suction head or lift, that might.

Google gives 9 mil.+ hits for pumping leg - although still not sure what the OP means.

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)
 
"I do not know what you mean by pump leg" I do not either
15- DIFFERENTIAL PRESSURE INCLUDES 3.3 m OF PUMPING LEG. TO BE CONFIRMED BY PUMP VENDOR / ENGINEERING ACCORDING TO FINAL LAYOUT - that's all I have

I thought about "head", but as if this term was used as "suction static head", for example, I guess this "pumping leg" should be something else.

Btw , there is a RICH AMINE FLASH DRUM with bottom tl elevated at 3 m above ground. Is it possible for differential pressure to consider this side.
 
The term “leg” could be used to indicate a pipe connecting a draining point of a steam line to a steam trap.
Maybe in your specific case it denotes differential pressure it is not measured between suction and discharge flanges but also taking into account 3.3 m of pipe.
 
I'm pretty sure it refers to head of some kind, are you pumping from or to the flash tank?

Can you post an elevation view of this.

Is there 3 something meters between pump centerline and lowest liquid surface in the vessel?

Pumping leg is not a term that I have come across (that I can remember) but by comparison with common piping terms that do include the word leg - such as dirt leg, cooling leg and dead leg - I would guess that it is a vertical line down from a tank to the pump and is probably there to give sufficient NPSHa to the pump.

I have seen piping done this way from flash tanks and condensate collectors and in specifying the head for the pump it is something that would have to be taken into account.

Perhaps it is referring to the static, or "elevation" portion of the head as opposed to the friction portion.
