Abstract
A pump assembly includes a chamber, a compressible conduit along a periphery of the chamber, an elongated sun member within the chamber, and an elongated planet member arranged to orbit around the sun member. The sun member includes a first portion at one axial end having a gear and a second portion at the other axial end. The planet member includes a first portion at one axial end with a gear engaged with the gear of the sun member and a second portion at the other axial end configured to be engaged with a section of the compressible conduit to constrict the section. The first portion has a different texture from the second portion, and teeth of the gears on either the sun member or the planet member are retained in an axial direction by the second portion of the other of the sun member and planet member.
