Selbstansaugen
Selbstansaugen refers to the ability of a pump to draw fluid into its suction line without external priming. This means the pump can operate even if the suction line is initially filled with air. This capability is crucial in applications where it is difficult or impossible to pre-fill the suction line with the liquid being pumped, such as in dewatering operations or when dealing with volatile liquids that might evaporate if left standing in the suction pipe.
Self-priming pumps achieve this by creating a partial vacuum within the pump casing. When the pump is
Various designs exist for self-priming pumps. Some utilize an internal air-water separator, while others employ a
