Also from Liquilob
Internal Gear Pump
An internal gear pump for precise, reliable and continuous transfer of liquids from thin to highly viscous, such as oils, resins and paints.
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
