What are the requirements after the gear pump stops running

When using a gear pump, it is necessary to follow the instructions for use, which will increase the service life of the gear pump. The normal use of gear pumps in fire protection systems also has corresponding reasons. Generally, it refers to the preparations that should be made before starting, the issues to be noted during use, and how to clean the medium inside the pump when not in use. Only by following the correct instructions can the service life of the gear pump be increased.
