What is pumping?

“Standing at the end face of the pump, the pump rotates in forward direction from the inlet to the outlet; otherwise, it rotates in reverse direction. ”What is the pump extraction here?
It should be the pump shaft; please take another look, OP
Pumping refers to the action of using a pump to draw something out, while the pump shaft is the shaft of the pump; their meanings are completely different.
There’s no such thing as pumping! Maybe the character was typed incorrectly. Note: It is not possible to determine whether a pump is rotating in forward or reverse direction by looking at its inlet and outlet; instead, one must consider the rotation direction of the impeller. When the tangent direction of the centrifugal force generated by the impeller’s rotation is in one direction, that indicates forward rotation, while the opposite direction indicates reverse rotation.
Ugh, if you want to judge it from the impeller, you first need to disassemble the pump; otherwise, you’d need X-ray vision. The simplest and most practical way is to look at the pump’s volute; the direction in which the volute decreases in size indicates the correct rotation direction of the impeller, while the opposite direction corresponds to reverse rotation
