Description of the seepex Progressive Cavity
Pump and Accessories
4.1
General Description, Design and Mode of Operation
Like all progressive cavity pumps, seepex pumps
belong to the rotating positive-displacement pump
family. The characteristic attribute of these pumps is
the special formation and arrangement of the two
conveying elements, namely the rotor and the stator.
The difference in the number of threads possessed
respectively by the rotor and stator produces a
chamber that opens and closes alternately in line
with the constant turning motion of the rotor, effecting
the continuous transportation of the conveying
product from the suction side to the pressure side.
The geometrical formation of the two conveying
elements combined with the constant contact that
exists between them result in sealing lines that effect
an airtight seal between the suction and pressure
side in every position of the eccentric screw, even
when the pump is stationary. The pump owes its high
suction capacity to this
sealing between the suction and pressure sides.
4.2
Mechanical Design
Please consult the sectional drawing, Point 9,
for the mechanical design of the pump. The data
sheet, Point 9, gives information on the design of the
pump housing, stator, rotor and rotating components.
Refer to document OM.SEA. _ _, Point 9 for
information on the design of the shaft seal.
The data sheet, Point 9, specifies details of the
design of the drive engine. Further details are
given in the appended manufacturer’s documents,
Point 10.

4.5
Design Variants
Refer to the data sheet, Point 9, for the design of the
seepex progressive cavity pump. Other design
variants are possible, whereby seepex must first
check whether a particular pump is suitable for the
intended purpose.

Installation of the Fully Assembled Pump
•Installation in conformity with data sheet
Installation of the pump is permissible only in
accordance with the data sheet specifications and
the associated basic drawing, see Point 9. Any
change in the position must be checked and
approved by seepex.
•Tension-free mounting of pump
This rule applies to pumps with and without drives,
to versions with and without baseplate, for
mounting on the foundation or other bearing
elements. The entire area of all bearing surfaces of
the machine must rest on the ground. Any
unevenness must be corrected by appropriate
supports.
ìCorrect seating of drives
All drives have been aligned ready for operation
and mounted by seepex. However, displace-ments
may occur during transport or installation. For this
reason, check that the alignment and fastening of

6.5
Commissioning
6.5.1
Initial Startup/Re-starting
CAUTION
Every seepex progressive cavity pump is designed
for the specific operating conditions documented in
the data sheet. Commissioning is permissible only if
the operating conditions conform with those
indicated in the data sheet. Although the potential
usages of the seepex pump are not confined to the
specified operating conditions, any change in the
original conditions must be checked and approved
by seepex.
The right to make claims under the warranty
agreement will be annulled if operating conditions
are changed without prior approval by seepex.
6.5.2
Avoid Dry Running of Pump
CAUTION
The dry running of a pump increases the friction
between rotor and stator, quickly causing an
unacceptably high temperature to develop on the inner
surface of the stator. This overheating leads
to burning of the stator material and the total
failure of the pump.
For this reason it is necessary to ensure that the
suction-sided flow never dries up completely.
If a continuous flow cannot be guaranteed for the
plant, it is essential to fit the seepex dry running
protection device TSE, available as an optional
accessory.
6.5.3
Check Pressure at Suction and Pressure Flanges
6.5.3.1
Safeguard Pump Against Excessive
Pressure at the Suction Flange
The seepex pump is designed to
operate with the pressure at the suction
flange (suction head or inlet pressure)
specified in the data sheet. Deviating
pressure conditions may lead to the
failure and/or destruction of the shaft
seal or entire pump.
For this reason the suction pressure
specified in the data sheet must be
guaranteed. Appropriate monitoring
devices are oil-filled contact mano-
meters that deactivate the pump.
6.5.3.2
Safeguard Pump Against Excessive Pressure at
the Pressure Flange
The seepex
pump operates according to
the positive displacement principle.
Operation of the pump against an
excessive pressure caused by closed
valves, by high pressure losses in the
piping or by product sedimentation will
lead to the destruction of the pump,
drive, pipe work and/or downstream
equipment. Every progressive cavity
pump must therefore be protected
against overpressure. Safety valves with
bypass pipes or oil-filled contact
manometers that disactivate the pump
are appropriate protective devices.
6.5.4
Drive Engine
Consult the attached manufacturer's
operating instructions, Point 10, for
information on commissioning the drive
engine.

Establish Clear Passage Through Pipelines
CAUTION
To prevent damage to the pump the unhindered flow
of liquid must be guaranteed between the points of
entry to and exit from the pipeline. For this reason,
open all relevant valves etc. prior to activation of the
pump.
6.6
De-commissioning
6.6.1
De-activation
The electric connections must be
switched off and protected against
accidental re-activation. Observe the
safety regulations applying to the plants.
6.6.2
Stationary Pump
The pump and all optional equipment must be
provided with the following protection modes while at
astandstill:
-Frost protection
-Protection against solid particle deposits
-Protection against sedimentation of the medium
-Corrosion protection for parts in contact with
the medium
We recommend that the pipeline and pump be
emptied for the duration of the plant standstill.
Following evacuation, the pump should be preserved.
6.6.3
Evacuation of the Pump
The pipeline must be evacuated on the
suction and pressure side or
shut-off directly behind the pump
connections. Drain any residual liquid in
the pump casing by opening/ removing
the screwed sealing plugs (705) and
(502), sealing rings (706) and (503).
CAUTION
Coated casings or housings without
screw plug have to be drained by the
connection branch (SAG and DRS).
Refer to the data sheet and the
sectional drawing of the associated
operating instruction for information on
the pump design.
Conveying medium residues always
remain in the rotor/ stator chambers
and may run out during transport or
disassembly of the pump. When
conveying aggressive or hazardous
media, therefore, wear appropriate
protective clothes during
all installation work.
6.6.4
Disassembling the Pump
Dismantle the pipe work by removing the flange
bolts (SCH) and flange seals (DFL) or the threaded
connections (G).
Disassemble the pump together with the baseplate
(GPU) or, as applicable, without the baseplate
(GPU) following removal of the bolts (SCH) at the
pump feet.
Block-design pumps with direct flange-
mounted drive engine are liable to
become unstable during disassembly.
Stability can be restored by propping up
the drive engine.
6.6.5

Dismantling the seepex Progressive Cavity Pump
Tools are required for dismantling and re-assembly.
These tools are listed in Point 9 of the document
OM.SPT.01.
The stator (601) and the rotating pump parts can be
exchanged in site. The rotating pump parts can be
dismantled as a complete rotating unit (RTE) (Point
7.3.4) or as individual components (Point 7.3.5).
Before commencing the dismantling
of pump parts, safeguard the pump
against tipping over or falling down
by fastening it at the lantern (200).

Before dismantling the stator (601), provide it with a
support (S) to prevent it from falling.
.
7.3.2
Stator (601) - Dismantling
•Maintenance tip:
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 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 shaft against rotation.
While dismantling the stator (601) with tool
(W2/see Point 9) prop up the rotor (600) and the
suction casing (500) with support (S) to prevent it
from falling.
