P = head * density * specific gravity.
If discharge throttle, pressure will increase, so the head will increase.
So total head suction + discharge will increase.
If discharge throttle, pressure will increase, so the head will increase.
So total head suction + discharge will increase.

I think that no any effect of throttling of discharge on the suction lift. Because according to suction life formula no any term exist related to this. But yes output head i.e. manometric head will increase.

It's is because manometric head required for pump decreases when discharge end is throttle.

How?

If the discharge is throttled, the flow decreasing causes the decreasing NPSH require.
So the suction lift should be decreased right ?
So the suction lift should be decreased right ?

Please explain the effect of discharge head on the suction lift?
