摘要： A device for tangential flow filtration includes a filter unit having first and second fluid openings, a filter element and a permeate opening, a first flow connection to connect the first fluid opening to a reservoir, a second flow connection to connect the second fluid opening to the reservoir, a first centrifugal pump in the first flow connection to convey the fluid from the reservoir to the filter unit, a first controller to actuate the first centrifugal pump, the filter unit designed such that the fluid for tangential flow filtration is capable of flowing substantially parallel to the filter element, a second centrifugal pump in the second flow connection, with which a counter-pressure is capable of being generated at the second fluid opening, and a second controller to actuate the second centrifugal pump.

摘要： A flow regulator includes a first sensor determining a first actual value of a first flow parameter of the fluid, a pre-pressure regulator setting a predefinable pre-pressure at a pre-pressure outlet of the pre-pressure regulator, and a regulating pump. The fluid is capable of being supplied to the pre-pressure regulator at a plant pressure in an operating state via an inflow line and a pre-pressure inlet and capable of being conducted further to the regulating pump at the pre-pressure via a flow connection disposed between the pre-pressure outlet and the regulating pump, the pre-pressure outlet being connected to a high pressure connection of the regulating pump in a flow communicating manner via the flow connection such that the fluid is capable of being supplied from the pre-pressure regulator of the regulating pump and guided away from the regulating pump via a low pressure connection into an outflow line.
