PURPOSE: To provide a sustaining liquid purifier with excellent operability and measuring accuracy by individually and intermittently measuring the flow rates of dialysis, replenisher and waste liquor to adjust the number of revolutions of corresponding pumps so that the actually measured values obtained coincide with respective set values. CONSTITUTION: Pumps 5 to 3 are functioned independently to individually and intermittently measure a the flow rates of a dialysis liquid, a replenisher and a waste liquor, respectively. When the flow rate of the dialysis liquid flowing through the dialysis liquid pump 5 is lower then a set value, the number of revolution of the pump 5 is increased and when it is higher, the number of revolutions of the pump 5 is decreased. In this manner, the flow rate is controlled to a value closer to the set value. When the flow rate of the resplenisher flowing through the replenisher pump 4 is lower than a set value, the number of revolutions of the replenisher pump 4 is increased and when it is higher, the number of revolutions of the replenisher pump 4 is decreased. When the flow rate of the waste liquor flowing through the waste liquor pump 3 is lower than a set value, the number of revolution of the waste liquor 3 is increased and when it is higher, the number of revolutions of the pump 3 is decreased.
