In the world of fluid power, gear pumps stand out for their simplicity, cost-effectiveness, and reliability. These pumps use meshing gears to generate pressure, forcing fluid to flow around them and out of the outlet. For lubrication, gear pumps rely on a small amount of oil from the pressurized side of the gears, which is bled through hydrodynamic bearings and vented back either to the low-pressure side or a dedicated drain port.
While gear pumps can be noisy compared to other types, modern designs incorporate features such as split gears, helical teeth, and high-precision tooth profiles that reduce pressure ripple and related issues. Moreover, catastrophic breakdown is rare in gear pumps, as wear on the housing and main bushings gradually reduces the pump's efficiency, ensuring timely maintenance.
One area that may require attention is gear pump housing, which refers to the casing that encloses the gears and bearings. Over time, wear and tear, as well as exposure to temperature, pressure, and chemical factors, can cause housing damage, leading to leaks, cracks, or other issues. Fortunately, gear pump housings can be rebuilt or replaced, depending on the extent of the damage and the cost-effectiveness of the options.
To choose the right gear pump housing for your application, you need to consider several factors, such as the pump's flow rate, pressure, viscosity, and temperature range, as well as the fluid type and compatibility. You also need to ensure that the housing meets industry standards and regulations, such as those related to safety, environmental protection, and performance.
