Impeller removal tool

An impeller removal tool assembly, comprising:

• a central body having an aperture defining an axis;
• a first puller arm pivotably pinned to the central body and having:
• a first angled ramp surface above the central body facing the axis;
• and
• a plurality of first teeth below the central body projecting toward the axis;
• a second puller arm pivotably pinned to the central body mirrored across the axis from the first puller arm, the second puller arm having:
• a second angled ramp surface above the central body facing the axis;
• and
• a plurality of second teeth below the central body projecting toward the axis;
• an arm rotator bolt threadably engaged with the aperture of the central body and coaxially aligned with the axis and a bearing coaxially aligned with the axis and positioned between the arm rotator bolt and the first and second angled ramp surfaces, wherein rotation of the arm rotator bolt translates the arm rotator bolt and the bearing along the axis with respect to the central body, wherein the bearing is configured to contact the first and second angled ramp surfaces during translation of the arm rotator bolt thereby causing the first and second puller arms to rotate between a first position in which the pluralities of first and second teeth are configured to be disengaged from a hub of an impeller, and a second position in which the pluralities of first and second teeth are configured to engage the hub of the impeller;
• and
• a central rod threadably engaged with and extending through the arm rotator bolt, the central rod being coaxially aligned with the axis, wherein rotation of the central rod translates the central rod along the axis with respect to the central body, the arm rotator bolt, and the bearing, and wherein the central rod is configured to interface with a pump shaft when the first and second puller arms are in the second position.
