Abstract
There is a problem of restoration and replacement of worn parts imported components and
assemblies, which are separate parts, as a rule, do not come, and only blocks replaced. To solve the
problem analyzed technology for manufacturing key components gear pump for possible recovery
or production. For this purpose, identified materials making up the drive shaft and the gear, the end
seal plates, bushings. Established kind of hardening of details; recommendations on the production
of repair kits to high-pressure gear pump. This approach can significantly reduce the costs of repair
work and maintenance of gear pumps and thereby implements the concept of import substitution.
Keywords
