Two kinds of baffle
Liquid in a tank, or product in a chute
Both stand in a moving stream and redirect it, but what wears them out is different. Tell us which one you have.
| DIAGRAM: wall-mounted baffles in a tank, flow arrows Wet process flow Water filtration | DIAGRAM: deflector plate in a chute, falling material and impact zone | |
|---|---|---|
| Where it sits | On the wall or inside a tank or vessel | At a chute or hopper transfer |
| What it does | Breaks up swirl, turns flow over or helps liquids separate | Slows, turns or places falling material |
| What wears it | Chemicals, temperature and cleaning | Impact, abrasion and buildup |
| What to tell us | The fluid and its concentration, temperature, cleaning and tank size | The material, particle size, moisture, drop height and where it hits |
What defines a baffle
Plate, edges and mounting
Send the design or the old baffle. These are the details we machine to.
-
Plate
Profile, overall size and thickness, flat or shaped.
-
Edges
Radiused or square, and edges that shed buildup.
-
Mounting
Bosses, brackets, fastener pattern and clearance to the wall.
-
Orientation
The angle and position the baffle sits at in the stream.
Ready to install. We can supply baffles with their mounts and brackets fitted, assembled with standard hardware, so there’s no second supplier.

No. We machine to your design, your drawing or the old baffle; the design stays with you or your equipment maker. Send the vessel and agitator details with your request.
No. Shell-and-tube heat-exchanger baffles are metal structural parts. We machine plastic baffles for tanks, vessels, chutes and hoppers.
Food-contact documentation is available for the grades used in food zones. Tell us what your process requires and we’ll quote the right grade.
We hold ±0.002" to ±0.005" on critical dimensions, depending on the plastic. We review your drawing and confirm the critical dimensions with your quote.
Timing depends on the baffle, material and quantity, and comes with your quote. For an emergency breakdown, ask about our expedited service.
