Abstract: The flushing pumping circuit (2,17 for conveyor units (1) for reaction mixtures contains an integrated heat exchanger and at least two conveyor units, through which the reaction mixture can flow in two directions. The two conveyor units have an inner flushing circuit (21) acting in a cooling capacity and an outer flushing circuit (28), which, viewed in the outflow direction, issue behind a closure body (16) in the pressure conduit (17). In the inner flushing circuit are contained a throughflow meter (20) and at least one stirring section (32) for the reaction mixture. Likewise, the outer flushing circuit (28) contains a throughflow meter (27) and at least one stirring section (33). Also in the outer flushing circuit is a diaphragm (25) and a regulating valve for adjustment of the throughflow quantity.
