What is Specific Suction about?

Specific speed (N) is a non-dimensional index for pump impellers, defined by the speed at which a geometrically similar impeller would deliver one gallon per minute against one foot of head. It influences the shape and design of impellers, with higher specific speeds indicating designs that generate head more through axial forces than centrifugal forces. Net Positive Suction Head (NPSH) measures the suction head to prevent vaporization of the fluid in the pump, with NPSH Required varying based on pump desig
