A fluid pump includes an upstanding wall on its base with a generally circular rotor spaced from and generally parallel to the wall to define a tube containing path therebetween with the rotor having at least one slot which defines the inner edge of an integral spring arm upon which a roller is mounted for making depressing contact with a resilient tube mounted in the path for forcing fluid through the tube and with the integral spring arm having sufficient resiliency to accommodate any back pressure developed in the tube.
