Claim:
1. A method for adjusting a dialysate volume flow in a dialysis machine with at least one discontinuous pump and a controller for generating a desired volume flow of the dialysate as pumped by said at least one pump over a pump cycle, said pump cycle including a plurality of pump strokes performed sequentially, said method comprising the steps of: determining a first constant energy value for a first pump stroke of the at least one pump in said pump cycle; operating the at least one pump over the first pump stroke with the first constant energy value; determining a constant energy value for each subsequent pump stroke in said pump cycle and operating the at least one pump at the constant energy value determined for said each subsequent pump stroke, the constant energy value for said each subsequent pump stroke being adapted over the pump cycle based on at least one of volume and pressure values measured during at least one previous pump stroke of said plurality of pump strokes.
