A brief discussion on external gear pumps

Thread Content

In the world of hydraulics, the various hydraulic components are always clearly categorized. For example, there are three types of hydraulic pumps that we know about: vane pumps, piston pumps, and gear pumps. Do you think that’s the end of it? No, vane pumps can also be divided into fixed-displacement vane pumps and variable-displacement vane pumps, while gear pumps can be categorized as external gear pumps and internal gear pumps. Although their names are similar, there are significant differences in their functions and performance. Today, Jingbo Cloud Commerce will discuss with you the advantages and disadvantages of gear pumps. A gear pump is a low-pressure hydraulic pump that is easy to use, features a simple and compact design, is small in size and light in weight, has good self-priming capabilities, operates reliably, has low costs, and is widely used. However, it also has serious drawbacks: it generates a lot of noise and has poor flow consistency. In applications with high requirements, such as those where consistent flow is essential, this type of gear pump is limited in its usefulness and essentially unsuitable for such purposes. Stay tuned to Jingbo Cloud Commerce, where we will introduce internal gear oil pumps next time.
