Abstract: A seal ring for improving the performance of a gear pump, primarily for vehicle transmissions, comprises the milling of a circular ring on at least one lateral face of an inner gear and an outer gear in a gear pump and inserting a friction reducing ring within the milled circular ring. The addition of this ring, especially on remanufactured gear pumps, will reduce the amount of transmission fluid leaking between the gears and the gear pump housing and also reduce the friction between the gears and the gear housing, thus providing more fluid to the transmission and also increasing the pressure while decreasing the amount of heat of the transmission fluid being circulated through the gear pump.
