Abstract: A fluid pump includes an inlet; an outlet; a motor; and an impeller rotated by the motor about an axis, the impeller being positioned axially between an inlet plate and an outlet plate. The inlet plate includes a channel that receives fluid from the inlet, the channel being defined by an inner wall and an outer wall. The channel has a first region extending over an angle of at least 150° and a second region extending from the first region over an angle of 61.8° to 71.8°. The inner wall has a first radius centered about the axis which is constant over the first region and the second region. The outer wall has a second radius centered about the axis which is constant over the first region and also has a third radius not centered about the axis which is constant over the second region.
