Body configurations
Jacketed and polypropylene bodies are not separate models. Any frame size in the series can be built in either configuration.
Jacketed Body · Jacketed
A temperature-controlled body for products that set as they cool.
- Continuously circulated heating
- Even temperature distribution
- Prevents the product setting as it cools
- Stainless steel body with an easily cleaned hygienic geometry
Typical use
Polypropylene Body · PP
For aggressive chemicals where stainless steel is not wanted.
- High resistance to acids and alkalis
- No corrosion or chemical erosion
- Transfer without metal ion release
- Mechanical seal options matched to the medium
