The pressure data indicated there apply only to
approximated static pressure load. In the case of
dynamic alternating pressure load, consult the
manufacturer.
1.4
Warranty
Our warranty for shortcomings in the supply is laid
down in our delivery conditions. No liability will be
undertaken for damages caused by noncompliance
with the operating instructions and service conditions.
If at any later date the operating conditions change (e.g.
different fluid conveyed, speed, viscosity, temperature
or supply conditions), it must be checked by us from
case to case and confirmed, if necessary, that the pump
is suited for those purposes. Where no special
agreements were made, pumps supplied by us may,
during the warranty period, only be opened or varied by
us or our authorized contract service workshops;
otherwise our liability for any defects will cease.
1.5
Testing
Prior to leaving our factory, all pumps are subjected to a
thorough test run and performance test on the test
stand. Only properly operating pumps, achieving the
performance assured by us, leave the factory.
Thus, compliance with the following operating
instructions ensures faultfree operation and full
delivery.
1.6
Availability
As a matter of principle, we recommend stocking
replacement pumps and withdrawable units (hydraulic
action system) where the supplied pumps are a
decisive factor in maintaining a production or delivery
process. In this way downtimes can be avoided, or
reduced to a minimum.

3.1
Packaging
Attention must be paid to the markings on the
packaging.
The suction and pressure sides and all auxiliary
connections must always be closed during
transportation and storage. The closing plugs must be
removed when the pump aggregate is installed.
3.2
Transportation
The pump or pump aggregate is to be safely
transported to the place of installation, if required by
means of lifting gear.
The generally applicable safety regulations for
lifting loads must be observed. The crane device
and cables must be adequately dimensioned. The
cables must not be attached to the attachment eyes
of the motor.
3.3
3.3.1
Preservation
In the case of storage or prolonged standstill, the
pumps must be protected against corrosion. In those
cases, an outside and inside preservation is to be
provided. The durability of the protection against
corrosion, which is limited in time, depends on the
composition of the preservative to be applied and the
storage conditions.
Under normal circumstances the pumps
have no special preservative.
At an additional charge we can, however, supply
pumps and replacement parts ex factory with a preservative adequate to the planned storage period.
We will be pleased to specify suitable preservatives for
you on request.
Points of preservation:
All bright and unvarnished parts (e.g. shaft ends, couplings, flange facings, valve and manometer connections).
3.3.1.2 Inside preservation
The preservative is to be applied by filling the pump. For
these purposes, the suction side of the pump must first
be closed with a dummy flange. During filling, the
pressure flange must be on a higher level than the
suction flange. During the filling process, the shaft must
be slowly cranked against the direction of rotation.
Filling must be continued until the preservative reaches
the sealing strip of the delivery flange, bubblefree.
Then the outlet side is to be closed with a dummy
flange.
Note: Not required for pumps made of stainless materials.
aggregate
In the case of vertically and horizontally mounted
flanged pump aggregates, it is advisable to attach the
cables to the wall/foot lantern or intermediate fitting
lantern (not shown).
During transportation ensure that the
aggregate is secured against toppling
over. The attachment eyes of the motor can be used to
secure it.
Points of preservation:
All bright parts inside the pump (e.g. pump casing inside, screw spindles, ball bearings, pressurerelief
valves).
3.3.1.3 Monitoring of preservation
In the event of prolonged storage, the preservation of
the pump must be checked by the customer at regular
intervals.
Every six months the pump level must be checked; if
necessary, preservative must be topped up to the
sealing strip on the pressure flange.
At the same time, the packing must be checked for
destruction, and repaired if necessary.
Note: Liability for damages caused by improper
preservation cannot be assumed by us.
Transport damage
Check the pump for damage on receipt.
Any damage detected must be notified immediately.
SM...AR..D/E4.2QM
ALLWEILER
3.3.1.4 Depreservation
Prior to setting the pump in motion, the preservative
applied must be removed.
Environmentally compatible disposal must be
ensured.
The preservative applied for inside preservation can
normally be removed by flushing the pump with the fluid
to be conveyed.
Alternative, suitable solvents may be applied for
removing the inside and outside preservation.
Appropriate solvents are for example: petroleum,
benzene, Diesel fuel, spirit, alkalis (industrial cleaners)
or any other wax solvents. Steam jet cleaning devices
with appropriate admixtures can also be used (allow
wax solvent to act beforehand).
Prior to startup after prolonged storage,
all elastomers (Orings, shaft seals) must
be checked for their elasticity of shape. Embrittled
elastomers must be exchanged. Elastomers of
ethylenepropylene rubber (EPDM) must always be
replaced. The pump must be filled with fluid to prevent
seizing of the components. A pressurerelief valve
attached or fitted in the pipeline must be checked for
passage.
Note: If on the plant side, the pipelines, (oil) tanks or
other parts are wetted with paraffincontaining
preservative, the entire plant must be depreserved as
paraffin is detrimental to the air separating capability of
oil. This may result in unsteady operation of the pump
and loud noise.
3.3.2
Storage
During storage of the pump, the suction and outlet
branches and all other supply and discharge branches
must always be closed with dummy flanges or dummy
plugs.
Storage should be in a dry, dustfree room. During
storage, the pump should be cranked at least once a
month. During this process, parts such as the shaft and
bearings should change their position.

Structural design
Threescrew pumps with a doublethreaded driving
spindle and two doublethreaded idler spindles,
enclosed in a housing insert with narrow running
clearance.
The delivery elements are installed in a pump housing
which is closed off by pump caps.
In the plinth pumps, the endside pump cover is designed as a round foot. Cartridgeunit pumps do not
have a pump casing. Depending on the installation situation, they can be installed in pump columns, submersed bodies, (hydraulic) tanks and cylinder casings
etc.

Mode of operation
Through the suction connection, the fluid is conveyed
into the suction chamber of the pump. From there the
fluid flows into the spindle chambers, which are
constantly formed by the rotary motion at the spindle
end on the suction side. By the translatory rotary
motion, the chambers filled with the fluid move from the
suction side to the outlet side. During this process the
closed chamber volume does not change. At the
spindle end on the outlet side the chamber opens
towards the delivery chamber. The fluid is steadily
pushed out into the delivery chamber from where it is
transported, through the pressure connection, into the
pressure pipeline.
The axial thrust acting on the faces of the profile flanks
on the outlet side is hydraulically balanced by an
appropriate dimensioning of the compensating piston
of the driving spindles and the compensating journals
of the idler spindles. Thus the bearing is relieved of the
hydraulic axial thrust.
Heating
Where heavy heating oils or other fluids which tend to
solidification when cooling are to be pumped, the following equipment is available for pump heating.

Checking the coupling alignment in case of horizontal setup on base plate (if used)
A complete delivered pump aggregate has been care
fully assembled at the factory. After proper installation,
and prior to startup of the pump aggregate, the align
ment of the coupling must be checked.
The check can be made with a straightedge and a
feeler gauge, or with other suitable equipment (such as
a laser alignment device).

2. Push on the coupling halves on the pump and motor
side with the aid of a pusher device until the shaft
end is flush to the coupling hub.
If no puller is available, heating the coupling halves
to approx. 100C (without rubber buffer) facilitates
pushing.
Impacts to the components of the pump
or motor must be avoided.

5.7.7
Check valve
It is recommended to install a check valve between the
pressure connection of the pump and the stop valve in
order to prevent the pump from running dry when it is at
a standstill and the pressure stop valve is open.
5.7.8
Vent valve
A vent valve must be provided at the highest point in the
pressure pipeline.
5.7.9
Filtering
To protect the pump against coarse dirt contamination,
we recommend as a matter of principle installing a filter
in the suction pipeline, mesh width 0.6 mm.
Note: The service life of the pump is decisively
influenced by the degree of dirt contamination of the
fluid being conveyed, that is, by the number, size and
hardness of the abrasive components.

1. Switch off the motor. Make sure the pump runs down
smoothly and evenly.
2. If a check valve is installed in the pressure pipeline,
the stop valve can remain open. If no check valve is
fitted, the stop valve must be closed.
3. Flush the pump and the pressure relief valve if need
be (refer to Section Flushing procedure).
Note: If fluids which tend to polymerization, cristallization, solidification or the like are handled by the
pump, the pump must be flushed out before each interruption of operation. The pump must also be
flushed out when the fluid is changed.
All interior areas of the pump and the pressure relief
valve through which the delivery medium flows must
be cleaned such that blocking deposits of solid
matter are prevented. It is advisable to connect the
pump to a separate flushing system. The pump
should be flushed with a suitable solvent, to which
some lubricant has been added, in order to ensure
emergency functioning during flushing.
For delivery of polyhydrics and isocyanates, the
flushing agent must be free of water. Softeners, such
as Mesamoll (supplier: BAYER), Genomoll
(supplier: HOECHST) or Plantinol AH and Plastomol DIDA (supplier: BASF), are suitable as lubricating and flushing agents. Other equivalent softeners
may also be used.
The flushing fluid is to be replaced when saturated.
For prolonged downtimes, the interior of the pump
should be filled with undiluted softener, and air humidity should be prevented from entering.
Flushing procedure
After stopping the motor and closing off the stop valves
in the intake and delivery pipe, start the flushing system
as follows.
1. Open the stop valve in the flushing system and start
the motor.
2. Flush the pump and the pressure relief valve sufficiently (for approx. 15 minutes). The flushing pressure should be approx. 3 bar.
3. After flushing, stop the motor and close the stop
valve in the flushing system.
4. Drain all flushing agent from the pump.
5. For prolonged downtimes, fill the pump with undiluted softener.

General
Trained Service fitters are available on request to carry
out mounting and repair work.
Where repairs are carried out by the operators own
personnel or by specialist fitters, it must be ensured that
the pump is fully drained and cleaned.
This particularly applies to pumps which are sent for
repair to our factory or one of our service workshops.
We must refuse acceptance of repair work on pumps
filled with fluid, for the protection of our staff and for
environmental reasons. Otherwise we must invoice the
customer/operator for the costs of environmentally
compatible disposal.
Where repairs are to be carried out on pumps which
have been operated with hazardous substances
and/or
environmentally
harmful
media,
the
customer/operator must inform its own personnel on
site, or our personnel where repairs are returned to our
factory or a service workshop, without being
specifically requested to do so.
In such cases a verification of delivery material, for
example in the form of a DIN safety data sheet, must be
submitted to us together with the request for a Service
fitter.
Alternatively, you can request a certificate of safety
(form no. 448/191) from our Service department, filling
it out truthfully, correctly and in full. Send the completed
form to the center commissioned with carrying out the
repair, or hand it to our Service fitter.
