A peristaltic pump includes a rotor and a track assembly. The track assembly is spaced from the rotor to receive n tubes therebetween, where n=2m with m a positive integer &#x2265;2. The tubes are manifolded to one another at a discharge port. One of the rotor and the track includes an occlusion surface for each of the n tubes. The occlusion surfaces are located at n different angular positions. The angular offset between the occlusion surfaces offsets pulsation associated with each tube so as to reduce overall pulsation at the discharge port.

Peristaltic pump

A peristaltic pumphead is provided that has a pumping chamber within which is disposed a pressing element for exerting a peristaltic action on a tube extending within the pumping chamber, and an auxiliary chamber which in normal use is a dry chamber. The pumping chamber and the auxiliary chamber are arranged in fluid communication such that liquid which escapes from the tube into the pumping chamber flows from the pumping chamber into the auxiliary chamber.
