Tilavuuspumppu
Tilavuuspumppu, often translated as positive displacement pump, is a mechanical device used to move fluids by trapping a fixed amount of fluid and forcing or displacing it into a lower pressure system. Unlike centrifugal pumps, which rely on kinetic energy to move fluids, positive displacement pumps deliver a consistent flow rate regardless of the discharge pressure. This makes them ideal for applications requiring precise metering or the pumping of viscous fluids.
There are two main categories of positive displacement pumps: rotary and reciprocating. Rotary pumps, such as
The principle of operation for a positive displacement pump involves creating a seal around a specific volume
