Matters Need Attention:
 
In order to prevent the external gear pump's drive shaft from being driven out of the housing when there is a high pressure on the suction side, the drive shaft must be relieved. It protrudes from both sides of the housing and is sealed, so that atmospheric pressure predominates on both sides of the drive shaft.
