Multistage centrifugal pumps - overview
Multistage centrifugal pumps from STROBL Pumpen are horizontally or vertically installed, single or multistage, normal-priming centrifugal pumps.
STROBL's multistage centrifugal pumps are designed in block construction with lantern or basic column construction with coupling for horizontal or vertical installation (also available as submersible pump). Special designs on request.
The impellers are multi-vane with two cover disks.
Multistage centrifugal pumps from STROBL Pumpen draw in radially and convey the medium with one or more impellers radially to the discharge nozzle positioned in the centre of the axis.
The motor power is transmitted via the pump shaft to the impeller.
Depending on the design, the pump head is sealed with single or double mechanical seals; special designs are also possible.
The delivery pressure as well as the delivery rate are determined by the pump performance (pump characteristic curve), the impeller geometry, as well as the suction- and pressure-side pressure losses of the system. The delivery rate as well as the delivery pressure can also be varied by speed control or bypass solutions.

The main field of application for the multi-stage centrifugal pumps of the SKP series is pressure boosting in plant construction and process technology. Due to the suitability for high system pressures and the possibility of using different materials, the pumps are suitable for many application scenarios.
Multistage centrifugal pumps from STROBL Pumpen are used, for example, in the following sectors:
- Chemical industry
- Petrochemistry (oil & gas)
- Process plants / process technology
- Pressure boosting plants
- plant engineering
- Industry (oil & gas)
- Osmosis plants
Sealing is done with suitable sealing materials (e.g. NBR, EPDM, PTFE or FKM), both on the static seals and on the mechanical seals. The sliding surfaces are made of carbon A or SiC (silicon carbide), depending on the design.
STROBL pumps are characterised in particular by the application-specific adapted sealing technology; special solutions for difficult media are also possible (e.g. solids-laden).
