A worm pump has an eccentric worm rotor rotatable in a stator to compress tubes which thus carry respective flowable media so that these media are forced through the tubes. The tubes are received in recesses in the stator wall which preferably is composed of a rubber with a Shore .ANG. hardness of 90 to 95. The pump is easier to manufacture, virtually free of corrosion caused by the pumped medium, can be used to pump more than one medium, and provides smooth flow of the pumped liquid substantially free of pulsation.
