Pumping action is achieved through meshing between a something may have blocked the gears or there could be a problem in the connection between the pump and circuit. No discharge. Excessive noise in a hydraulic system can be caused by the presence of air in the hydraulic oil. Introduction of air into the system can be the result of a leak in the suction line, air bubbles entrained in the oil, or insufficient pump or motor inlet flow which results in a vacuum. Gear pumps problems are divided into two main categories: those resulting from the pump itself, and others from issues other than the pump. Figure 2.
