摘要

The pump arrangement (100) has three housing modules, where a housing module (110) has a section with a diameter (D1) and a passage recess (111) for inserting a drive shaft. Another housing module (120), for the admission of a pump unit (122), has another passage recess (121) for the admission of the drive shaft. The latter housing module is coupled with the former housing module. An independent claim is included for a method for manufacturing a pump arrangement.
