Pump with two rotary driven displacement bodies in housing - has displacement bodies arranged on parallel running shafts with bearings on both sides.

摘要

The housing face wall has two parallel, spaced sections (9,10) which with formation of a rear housing section (7) are joined to one another in an axial direction. For each shaft end (22) a bearing casing (17) passing through the housing section is provided, which via a ball bearing (13) is located against the one face wall section (17) and via a sealing device (17) is sealed against the other, inner face wall section (10). The rear housing section (7) is screwed to the housing (1) via a ring flange. A wear plate limits the pump inner chamber against the rear housing section. USE/ADVANTAGE - A pump for moving relatively aggressive media with a wear plate between the housing and the rear housing section.
