This 11" x 20" nylon mess is just enough to cover a 6 inch pipe.
When a pump is used in a lake, pond or in other open water applications, a flow sleeve is required to increase the water flow velocity to better cool the motor. Please refer to our website Flow sleeve for more information.
This 11"x20" sheet is our standard size. If you order multiple sheets in even number, we will ship you a continuous sheet cut from a 22 inch roll so it can be used for a larger sleeve or a filtration cage to fit your design.
Once you understand the principle of the flow sleeve, you can use your imagination to design your own one.
