Description

When your Fimco boomless sprayer starts putting out uneven spray patterns or losing pressure at the center nozzle, this little diaphragm is likely the culprit. The internal diaphragm is built to maintain consistent pressure and flow, so your spray patterns stay uniform even when pressure fluctuates during operation. A worn or damaged diaphragm means your spray coverage suffers, and that’s the last thing you need when you’re trying to get herbicide or liquid fertilizer applied evenly.

What You’re Getting

Direct replacement diaphragm that restores proper pressure regulation
Maintains consistent spray flow even when pump pressure varies
Chemical-resistant construction that handles harsh herbicides and fertilizers
Precise fit for center nozzle assembly on BL30NS and UTL boomless units

Built for Real Farm Work

This nozzle assembly is designed for FIMCO’s wet style boomless systems, the kind you’ll find on ATV sprayers, pull-behind units, and 3-point hitch sprayers. Whether you’re spraying pastures, fence lines, or doing spot work around the farm, this adjustable setup gives you the versatility to handle different spray jobs with consistent coverage from your center nozzle.

Made to Last

Farm pumps deal with chemicals, weather, and constant use. These replacement feet are built to handle that environment, maintaining their shape and dampening qualities through seasons of hard work. This diaphragm uses the same durable materials that stand up to chemical exposure and temperature swings that come with spray season.

Installation Notes

Replacing this diaphragm is a straightforward job—just disassemble the center nozzle housing, swap out the old diaphragm for the new one, and reassemble. Make sure all O-rings and seals are clean and properly seated before putting everything back together. Test your spray pattern after installation to confirm even coverage across your boom width.
