摘要
multistage type centrifugal pump, with a removal of a subset of the total pump output of the pump casing (1) behind the last pumpenstufe (4) a stru00f6mungsfu00fchrungskanal is arranged, an additional wheel nearer to the impeller and the selected subset at the subset of another pipe).is a well-known, drucksteigerndes and within the centrifugal pump behind the last pumpenstufe (4) (5) generates an internal sonderlaufrad in pressure increased subset.this subset is one with a stru00f6mungsteiler (7) bearing system (6), with the stru00f6mungsteiler (7) at least two zweigleitungen (8, 9) and at least a branch channel (8) with a valve (12) is fitted.it is in an ongoing operation of the centrifugal pump to reduce the abgedrosselten subset of sonderlaufrades back on the final pressure of the centrifugal pump.
