Gear pumps often get stuck

Column A operates at an absolute pressure of 1000 Pa, while column B operates at 200 Pa. A high-vacuum gear pump is located at the bottom of column B to serve as a circulation pump. There is also a high-vacuum gear pump under Tower A that supplies fluid to the circulation pump. When Tower A becomes empty during shutdown, the gear pump located beneath it gets stuck; this happens every time it is shut down. I would appreciate it if someone experienced could tell me what causes this How to solve it
Why is it stuck? Has the material become too hard after being steamed?
The viscosity of the material increases, leading to caking after cooling
Thank you for the answer. The cause has been identified: the material burned up and seized the shaft
