Impeller - Sierra Marine Engine Parts - 18-3247 (118-3247)

The design of the impeller is a crucial factor in deciding how well a centrifugal pump performs for Johnson/Evinrude Outboard 9.9 HP (1997-2000),15 HP (1997-2002). An impeller that is constructed properly maximizes flow while reducing turbulence and improving efficiency.

Open impellers' structural integrity is jeopardized. They are typically found in inexpensive, compact pumps as well as pumps that handle suspended materials.

Energy from the prime mover is transferred to the liquid by the impeller. Depending on whether they have front and back cover plates, water pump impellers are categorized as closed, semi-open, or open.
Based on their design, the blades are divided into cylindrical and twisted blades. Closed-type impellers, which are used in single-suction and double-suction centrifugal pumps as well as single-stage single-suction centrifugal pumps, typically have 2–12 back-curved blades and good operational efficiency. There are balance holes at the blade roots of some impellers. Half-open and open impellers, like the impeller of a sewage pump, feature a few blades, often 2 to 5. Slurry, granular liquid, or sewage are the usual materials that are utilized for pumping.
