Leading enterprises in the internal gear pump market are concentrating on creating innovative solutions such as the 4-quadrant internal gear pump to gain an advantage over competition. The 4-quadrant internal gear pump is a specific kind of gear pump in which the interior gears are engineered to work in four unique phases or quadrants. This design ensures steady fluid movement while reducing pulsations and enhancing efficacy in a wide array of industrial uses. For example, Moog Inc., a manufacturer based in the United States, introduced EPU-G in October 2024. Moog's EPU-G is equipped with a freshly designed 4-quadrant internal gear pump and a high dynamic servomotor, delivering flow rates ranging from 20 to 85 l/min and pressure levels reaching 345 bar. Its variable speed, energy-efficient functioning, and compact design lower complexity and maintenance requirements while improving the overall performance of the machine.
