The Bell nozzle, sometimes called a Mushroom nozzle due to its rounded shape, creates a sheer bell of water. The nozzle can be adjusted by tightening or loosening the top brass plate which allows for fine tuning of the bell size. The bell shaped water cascade almost appears like a half bubble on the pond. It leaves a delicate sound and is ideal for formal lily ponds or any backyard pond. Can also be used in formal commercial basins.
Nozzle is female thread.
The overall diameter of your Bell spray pattern a will depend on the pump flow and the size of the nozzle chosen. Ensure that the hose or PVC tubing that connects your pump to the nozzle is a sufficient diameter. Always try to use a pipe with the same diameter as the nozzle to minimize loss of flow from pipe friction.
The following chart is an approximate detailing of various spray heights with various pump flows at required head rating. Ensure your pump gives the recommended flow at the specified head (height).
