What does surface booster pump mean in practice?
It creates flow and pressure while the vessel reduces starts; suction ability is limited by physics and suction-line losses.
When does it matter?
A leak on the suction side can draw air without visible water leakage and cause loss of prime.
Which solutions are related to it?
Size it for pumping level, head and demand and provide a check valve, airtight suction, priming and dry-run protection.
