ABSTRACT:
Two or more sets of liquid substance feed means are provided each which consists of a supply device, a transport pipe and a delivery pump. These feed means are connected through a valve to a single transport pipe and back pressure devices are provided in all but one of the liquid-substance feed means. While a liquid substance is being fed by one of the feeding means, another liquid substance having different properties is passing in the other feed means and using the back pressure device provided in the latter means, the flow rate and the pressure of the latter liquid substance are controlled as the same as those of the former being fed by the former feed means. Being switched over, in this condition, from the former feed means to the latter to feed the latter liquid substance, two or more kinds of liquid substance having different properties can be fed sequentially at predetermined pressure and flow rate.
