Positive Rod Displacement Technology - Exact Ratios Every Time
No matter the material, positive rod displacement metering proportions materials to the exact volumetric ratio every time; even with notoriously difficult materials like abrasives that can cause machine wear.
Principle
As the metering rod moves through the cylinder, material is directed by inlet and outlet valves to ensure the displaced material is directed downstream. The shot size of the dispense is determined by the distance the metering rod travels whereas the flow rate is determined by the speed of such travel.
Advantages
- High shot adjustability
- Minimal wear components
- Ability to handle abrasive materials
- Air can be purged from the top of the cylinder without turnover
- Easy to access and complete repairs
- If a new ratio is required, only the rod would need to be changed as opposed to the entire cylinder
- Provides longer seal life than rotation-based metering principals
