Dismantling the seepex Progressive Cavity Pump
Tools are required for dismantling and re-assembly.
These tools are listed in item 9 of document
OM.SPT.01.
The stator (601) and the rotating pump parts can be
exchanged at site. The rotating pump parts can be
either dismantled as a complete rotating unit (RTE)
(item 7.3.4) or as individual components (item 7.3.5).
Before commencing the dismantling
of pump parts, protect the pump against
tipping or falling down by fastening it at
the drive (ANT).
7.3.2
Stator (601) - Dismantling
• Easier assembly:
Disassembly of the stator can be made consider-ably
easier by first moistening the inner surface
of the stator with antiseize agent (soft or liquid soap).
Before removing the pressure flange (700), pour the
antiseize agent into the opening between rotor and
stator on the pressure flange side. Several clockwise
(see item 6.2.5) revolutions of the rotor will then
distribute the antiseize agent over the inner surface
of the stator reducing the friction between rotor and
stator considerably.
• Lock drive shaft against rotation.
Dismantling of the stator (601) with tool (W13/see
item 9.).
