  • Peristaltic pump for pumping a liquid and method for operating a peristaltic pump
    Patent number: 9458846
    Abstract: A peristaltic pump (1) for pumping a liquid comprises a flexible tube (2) for guiding the liquid to be pumped, a compression means (5) being actuatable for compressing the flexible tube (2), an upstream valve means (3) arranged in an upstream direction with respect to the compression means (5) and being actuatable to selectively open or close the flexible tube (2) upstream of the compression means (5), and a downstream valve means (4) arranged in a downstream direction with respect to the compression means (5) and being actuatable to selectively open or close the flexible tube (2) downstream of the compression means (5). A drive shaft (6) is provided which is rotatable for periodically actuating the compression means (5), the upstream valve means (3) and the downstream valve means (4).
