Rotating Pump Parts - Re-assembly
Prepare main components:
Prepare rotor (600), coupling rod (400) and
plug-in shaft (307) as described in document
OM.PJT.01e Point 2. to 2.3
Joint (G) re-assembly as described in document
OM.PJT.01e Point 3.
7.4.4
Suction Casing (500), Casing Gasket (501) - Re-
assembly
Fit protective cover (SH) on rotor (600) and prop it up
with support (S). Prop casing gasket (501) and
suction casing (500) by support.
7.4.5
Stator (601) - Assembly / Re-assembly
Maintenance tip:
Disassembly of the stator can be facilitated con-
siderably by first moistening the inner surface of the
stator with antiseize agent (soft or liquid soap).
Before removing the pressure flanges (700), pour the
antiseize agent into the opening between rotor and
stator on the pressure flange side. Several clockwise
(see Point 6.2.5) revolutions of the rotor will then
distribute the antiseize agent over the inner surface
of the stator and reduce the friction between rotor
and stator considerably
Lock drive (ANT) shaft against rotation. Using tool
(W2/see Point 9), turn stator (601) clockwise and
simultaneously push it over rotor (600), propping up
stator with support (S) at the same time.
7.4.6
Pressure Flange (700) - Assembly
CAUTION
Tighten tie bolts (602 and 603) in equally.
