This section contains a description for installing the internal gear pumps.
9.1 Assembly of pump and motor
If any assembly points differ from this description, please contact Voith Turbo
H + L Hydraulic.
The hydraulic system must be depressurized before any work is carried out on the
pumps.
During assembly, ensure that:
• the pump and motor shafts are aligned,
•
sufcient couplings are used (elastic or curved tooth couplings), that the coupling
is correctly positioned,
• the pump drive is free of axial and transverse forces. A drive via the gears, belt,
or chains without attachment bearings is only possible in limited cases, and
requires the approval of Voith Turbo H + L Hydraulic,
• the pump is not put under any strain as a result of pump misalignment,
• there are no strains as a result of incorrectly assembled pipelines,
• the coupling parts are assembled without excessive force,
•
for assembly of the coupling parts, no assembly paste containing solid lubricants
or other abrasive substances (eg copper or silver paste, etc.) may be used. After
inevitably migrating to the pump’s shaft seal, these substances cause damage of
the seals and general pump damage with resulting leakage,
•
permanent air entry into the hydraulic system causes damage to all uid-carrying
components and the pressure uid itself.
Voith internal gear pumps can be designed either with left-hand rotation or
right-hand rotation. The rotation is marked on the pump housing with an arrow. The
rotation of the drive must match the rotation information for the internal gear pump.
The pump shaft contains an assembly thread (see page 41) as standard.
