Stainless Steel Inline Pipe Mixers

Cutaway View

Use for pH control and chlorination. These mixers are more chemical resistant than nylon mixers. Also known as static mixers, they install in your pipeline and mix liquid as it passes over fixed spiral blades. They have no moving parts and require no external power source.

Number of Blades—Follow these steps to determine your Reynolds Number, which indicates if you need a mixer with 6 or 12 blades.

1. Multiply flow rate (gpm) by 3,157

2. Multiply specific gravity by total of Step 1

3. Multiply viscosity (cp) by pipe ID (inches)

4. Divide total of Step 2 by total of Step 3

Inline Tube Mixers

Cutaway View

These mixers have unthreaded ends that can be secured with compression or push-to-connect fittings. Materials mix as they pass over the fixed spiral blades. They require no external power source.
