Johnson Pump Aerator Head - 9"

The Johnson Pump Aerator Head – 9" (Part No. 90291PK) is a precision spray head assembly engineered for aeration and fluid distribution applications requiring customizable spray patterns and flow control. This 9-inch aerator head delivers consistent, uniform spray across a wide operational range, making it ideal for marine, agricultural, and industrial fluid handling systems where precise atomization and coverage are critical.

Johnson Pump's modular aerator head design allows for configuration flexibility across multiple applications. The 9-inch length provides optimal spray distance and penetration, while the assembly's compact weight (0.1 lbs) minimizes system load and installation complexity. Whether integrated into bilge systems, cooling circuits, or agricultural spray rigs, this aerator head maintains performance across varying pressure conditions. The ability to customize fit, size, and flow capacity means systems can be precisely tuned to match specific volumetric and operational requirements without requiring complete component replacement.

This aerator head serves marine engineers, equipment manufacturers, and system integrators who need reliable aeration solutions for saltwater bilge pumps, freshwater circulation systems, and fluid transfer applications. The modular construction allows technicians to build spray assemblies matched to exact specifications—critical in marine environments where off-the-shelf solutions often require costly modifications or compromise performance. Johnson Pump's engineering focus on customization means this component integrates seamlessly into both retrofit applications and original equipment designs.

Aerator heads are fundamental to pump efficiency and system longevity. Johnson Pump maintains a reputation for manufacturing durable, field-proven fluid handling components used across recreational and commercial marine vessels. This 9-inch aerator head represents the precision engineering standard that professionals depend on for consistent performance in demanding saltwater and freshwater environments.
