What reduces internal leakage in a hydraulic gear motor?

Wear plates play a critical role in reducing internal leakage in a hydraulic gear motor. Their purpose is to create a smoother interface between moving parts, minimizing the gaps where fluid could escape. By fitting snugly within the motor, wear plates maintain better contact and alignment of the gears, which prevents hydraulic fluid from bypassing and leaking out of the system.

This is especially important in hydraulic applications where maintaining pressure is crucial for efficiency and performance. Wear plates not only help to decrease internal leakage but also contribute to the longevity of the motor by reducing wear and tear on the gears and other components. Their design and positioning are integral to the overall function of the hydraulic system, ensuring optimal performance.

In contrast, while seals are designed to prevent leakage, they often work in conjunction with other components like wear plates. Check valves and filters serve different purposes related to flow control and fluid cleanliness, respectively, rather than directly addressing issues of internal leakage within the motor itself.
