Jet pump DN 100
Jet pumps are devices that generate a pumping action by using a driving fluid as an energy carrier. No mechanical drive is required for the propulsion.
- The high-pressure motive medium is accelerated to the maximum in a nozzle. A static pressure drop occurs. The pressure of the flow here is lower than the ambient pressure.
- The accelerated motive medium meets the much slower suction medium, creating a shear stress in the boundary layer.
- This causes a transfer of momentum to the suction medium, which is accelerated and entrained.
- The acceleration of the suction medium leads to a static pressure drop, which creates a suction effect and further suction medium is supplied.
- The downstream diffuser causes the pressure of the mixture to rise again.
- Particularly robust pump type with very low wear and tear
- High reliability, as no moving parts are necessary
- Low-maintenance, thus sustainably reduces plant downtimes, which reduces operating costs
- No mechanical drive necessary, the energy of the propellant (e.g. steam) is used to generate the pumping action
- Energy efficient through precise dimensioning
- Very versatile, motive and suction medium are variable
- Production in different materials possible, suitable for customer requirements
- Can transport the largest volume flows compared to other vacuum pumps
Jet pumps find applications in a wide range of processes and are individually designed for the intended use.
