Abstract: A peristaltic pump is provided, which may have auxiliary fluid introduction, for a plurality of resilient pump tubes progressively occluded concurrently along a portion of their lengths, recurringly, to advance fluids therethrough by a pressure roller assembly; and a control system for the pump to render the roller assembly inoperative to advance fluids. A platen is mounted for movement from an operative position, in which the pump tubes are engaged and sandwiched between the platen and the roller assembly, to an inoperative position in a direction away from the roller assembly. In the inoperative position of the platen, a tube or tubes of the auxiliary fluid introduction, which includes a pressure pin cooperating with a pad engageable with the tube or tubes therebetween, are released. The platen is power-operated to move to at least one of the two aforementioned positions thereof.
