What is the difference between an external and internal gear pump?
An external gear pump uses two interlocking gears to move fluid through a system. Gear Pumps and Motors from the Kings Mountain facility (300, 500, 600, Roller Bearing, etc.) are external gear pumps.
An internal gear pump uses a gear housed inside of another gear. The outer gear’s teeth are facing inside, and interlock with the inner gear’s teeth, which face out. Torqmotors and transmissions from the Greeneville facility (TE, TF, TJ, HTE, HTJ, etc.) are considered internal gear pumps.
