| 摘要 |
The invention concerns a device for tangential filtering of a fluid to be treated, comprising in a housing ( 2 ): a separating part ( 15 ) mounted in the first communicating chamber ( 11 ), in sealed contact with the neighboring positioning plate ( 4 ), to divide said chamber into first (V 1 ) and second (V 2 ) volumes externally and internally delimited by the separating part and communicating with said two-way circuit, comprising a communication passage ( 24 ) between the first volume (V 1 ) and the second volume (V 2 ), internally equipped with a turbine ( 23 ) of a circulating pump, provided with a driving shaft ( 25 ) extending outside the first chamber ( 11 ) to be connected to a driving motor ( 26 ), and a closure housing ( 13 ) mounted sealed on a neighboring positioning plate ( 4 ), delimiting the first communicating chamber ( 11 ) and sealingly traversed by the turbine ( 23 ) driving shaft ( 25 ).
