A pump producing peristaltic pumping action by sequentially occluding a tube between staggered curved surfaces. The pump includes a pump frame with a platen. The platen has an irregular surface forming a plurality of curved end surfaces. The irregular surfaces of the platen operatively interact with a pressure plate assembly having a plurality of pressure plates. The pressure plates are configured for translational motion. In operation the pressure plates are spaced one from another such that each one includes an end curved surface extending generally toward complementary staggered curved surfaces on the platen. Pumping is accomplished via a tube sandwiched between the platen and the pressure plate assembly. A drive operatively associated with the pump frame and pressure plate assembly drives the pressure plates in a wave sequence so as to sequentially occlude portions of the tube between staggered curved surfaces so as to promote a peristaltic pumping action within the tube.
