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. __, for information on
the design of the shaft seal.

Filling Up of Suction Side to Avoid Dry Running
at Startup
CAUTION
Before switching on the pump, fill the suction-sided
pump casing with fluid so that the first rotations will
lubricate the conveying elements immediately. A
small quantity of fluid is sufficient for lubrication; the
subsequent operation of the pump is self-priming,
even if an air column up to the liquid level remains.
6.2.4

Equipment for Protection of Persons
Machines must be fitted with mechanical
protective devices complying with DIN EN
809.
!Moving or working parts must be
protected against accidental contact.
!However, safety considerations demand
it be possible at all times

shaft seal is fully functional.
A protective guard is necessary in this
area only if components are mounted on
the rotating, smooth shaft.
!If pumps are operated with an open
suction flange/feed hopper, a suitable
protective guard complying with DIN EN
294 must be mounted.
!Country-specific protective regu-lations
must be observed at the site of
installation.
Prior to activation of the pump, check the
proper function of all protective
equipment.
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.

6.5.5
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). Casings
without screwed plug must be
evacuated by the connection branch
(SAG and DRS). Refer to the data
sheet and the sectional drawing of the
associated operating instruction, Point
9, 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. If conveying
aggressive or hazardous media,
therefore, wear appropriate protective
gear 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
Preservation/Storage
The pump must be preserved prior to storage.
Appropriate preservation measures must be agreed
with seepex. Always state the pump commission
number when making inquiries.

Holding Band (HBD) - Assembly
Tools required for the re-assembly, see document
OM.SPT.01.
•Prepare holding band
Onlyprefabricateddouble-bandholdingbands
should be used. The diameter (!)and in particular
the breadth (b) of the holding band is matched to the
universal joint sleeve.
•Test holding band
Thebentholdingband(HBD)mustfitagainstthe
holding band loop (SCL), if necessary apply
pressure with the tool/pliers (WZ).
•Assembly of holding band
Insert holding band in tool (W3/ see Point 9). Hold
free end of holding band with control lever (EX),
turn crank (KU) until the holding band is strained
and fitting against the holding band loop (SCL).
Carefully contract holding band until it fits inside the
circular groove of the universal joint sleeve.
•Correct holding band tension (HBD)
Correct
Holding band
(HBD) has
slightly con-
tracted outer
form of
univers-al joint
sleeve and is
stuck in
position.
Incorrect
Holding band
(HBD) is too
slack and
liable to slip.
Incorrect
Holding band
(HBD) is too tight.
Universal joint
sleeve will be
damaged/sheared
