Abstract (en)
[origin: EP2143954A1] The pump has a flow guiding part e.g. impeller, diffuser and sealing element, with a sectional surface layer (50) made of elastomer, where the flow guiding part is formed as a multi component-injection molding part. The injection molding part has a base structure (55) that is made of plastic, which is formed as a component, and the elastomer of the surface layer is formed as another component. The elastomer is a synthetic rubber e.g. silicone rubber. The sealing element is inserted between the diffuser and the impeller for guiding the flow.
