1. A pump assembly comprising:
a motor;
tubing; and
a pump head comprising:
an occlusion bed; and
a rotor guide having a rotor guide inlet side defining a rotor guide inlet groove and a rotor guide outlet side defining a rotor guide outlet groove, where the occlusion bed and the rotor guide together define at least a portion of a pathway for the tubing through the pump head;
a bezel surrounding an outer perimeter of the pump head, the bezel comprising a bezel upper side, a bezel lower side opposite the bezel upper side, a bezel inlet side extending from the bezel upper side to the bezel lower side, and a bezel outlet side opposite the bezel inlet side and extending from the bezel upper side to the bezel lower side;
wherein the bezel defines an inlet channel on the bezel inlet side and an outlet channel on the bezel outlet side, each of the inlet channel and the outlet channel guiding the tubing into the pump head,
wherein the bezel defines a fixed opening that is shaped to accept a pump head cover through the fixed opening of the bezel,
wherein the inlet channel has a first inlet width adjacent an inner surface of the bezel inlet side and a second inlet width adjacent to an outer surface of the bezel inlet side, the second inlet width being wider than the first inlet width such that the inlet channel flares away from the pump head,
wherein the outlet channel has a first outlet width adjacent to an inner surface of the bezel outlet side and a second outlet width adjacent an outer surface of the bezel outlet side, the second outlet width being wider than the first outlet width such that the outlet channel flares away from the pump head,
wherein an inlet bracket is attached to the inner surface of the bezel inlet side and an outlet bracket is attached to the inner surface of the bezel outlet side,
wherein the inlet bracket defines an inlet bracket groove that aligns with the rotor guide inlet groove and receives the tubing on the bezel inlet side, and
wherein the outlet bracket defines an outlet bracket groove that aligns with the rotor guide outlet groove and receives the tubing on the bezel outlet side.
