A blood purification apparatus is provided in which waste liquid is prevented from flowing through an ultrafiltration pump during ultrafiltration so that the performance and accuracy of ultrafiltration can be maintained over a long period. The blood purification apparatus includes an ultrafiltration line one end of which is connected to a dialysate introduction line at a position on a downstream side with respect to a duplex pump. The ultrafiltration line is provided with the ultrafiltration pump. The ultrafiltration pump is capable of performing ultrafiltration by drawing dialysate in the dialysate introduction line through the ultrafiltration line such that the volume of the dialysate to be introduced into a dialyzer becomes smaller than the volume of waste liquid to be drained from the dialyzer.

The disclosed subject matter relates to extracorporeal blood processing or other processing of fluids. Volumetric fluid balance, a required element of many such processes, may be achieved with multiple pumps or other proportioning or balancing devices which are to some extent independent of each other. This need may arise in treatments that involve multiple fluids. Safe and secure mechanisms to ensure fluid balance in such systems are described.
