4.3. Storage
Newly supplied pumps are prepared so that they
can be stored for at least 1 year. The pump should
be cleaned thoroughly before it is put into tem-
porary storage.
The following should be taken into consideration
forstorage:
• Placethepumponarmsurfaceandsecureit
against slipping and falling over. Submersible
pumps are stored vertically.
DANGER due to falling over!
Never set the pump down if unsecured. If the
pump falls over, this may lead to injuries!
• Ourpumpscanbestoredattemperaturesdown
to-15°C.Thestoreroommustbedry.Werecom-
mend a frost-protected room for storage with a
temperaturebetween5°Cand25°C.
• The pump is not allowed to be stored in rooms
inwhichweldingworkiscarriedout,because
the resulting gases or radiation can damage the
elastomer components and coating.
• Suction and pressure connections must be sealed
securely to prevent contamination getting in.
• All power supply cables must be protected
againstkinking,damageandmoistureingress.
ELECTRICAL hazard!
Damaged power supply cables can cause fatal
injury! Defective cables must be replaced by a
qualied electrician immediately.
BEWARE of moisture!
Moisture penetrating the cable will damage
both the pump and the cable. Never immerse
the cable end in uid and always protect it
from moisture.
• Thepumpmustbeprotectedfromdirectsunlight,
heat,dust,andfrost.Heatorfrostcancauseseri-
ous damage to impellers and coatings!
• The impellers should be checked at regular inter-
vals. This presents jamming of the bearings and it
renewsthelmoflubricationonthemechanical
seal.
BEWARE of sharp edges!
Sharp edges can form on the impeller and
hydraulic opening. There is a risk of injury!
Wear the necessary protective clothing, such
as protective gloves.
• If the pump has been stored for a long period of
time,itshouldbecleanedofimpuritiessuchas
dustandoilresiduebeforecommissioning.Check
that the impellers move freely and check the
housing coatings for damage.
Prior to commissioning, the ll level in the
sealing chamber should be checked and topped
up, if necessary!
Damaged coatings must be repaired immedi-
ately. Only an intact coating fulls its intended
purpose.
Please note that elastomer parts and coatings
become brittle over time. If the product is to be
storedforlongerthan6months,werecommend
checking these parts and replacing them as nec-
essary.Consultthemanufacturerfordetails.
4.4. Return delivery
Pumps that are returned to the factory must be
properly packaged. This means that impurities
have been removed from the pump and that it has
beendecontaminatedifusedwithuidsthatare
hazardoustohealth.
Forshipping,thepartsmustbepackedintear-
proofplasticbagsofsufcientsizeinsucha
manner that they are tightly sealed and leak-
proof.Furthermore,thepackagingmustprotect
the pump from damage during transportation.
Ifyouhaveanyquestions,pleasecontactthe
manufacturer!
5. Installation
In order to prevent damage to the product or seri-
ousinjuryduringinstallation,thefollowingpoints
mustbeobserved:
• Installation work – assembly and installation of
thepump–mayonlybecarriedoutbyqualied
persons. The safety instructions must be followed
at all times.
• The pump must be inspected for transport dam-
age before any installation work is carried out.
5.1. General
Forplanningandoperationoftechnicalsewage
systems,observethepertinentlocalregulations
and directives for sewage technology (such as
thoseoftheGermanAssociationforWater,
WastewaterandWaste).
Notethatpressuresurgescanoccur,inparticu-
lar with stationary installations where water is
pumped with longer discharge pipes (especially
withsteadyascentsorsteepterrain).
Pressure surges can result in destruction of the
pump/systemandnoisepollutionduetoap
knock. Pressure surges can be prevented by ap-
plying suitable measures (e.g. non-return valves
with an adjustable closing time or special routing
ofthedischargepipeline).
Afterpumpingwatercontainingcalcium,clayor
cement,thepumpshouldbeushedwithpure
water to prevent encrustation and avoid related
breakdowns later on.
Ifyouareusinglevelcontrol,makesurethatthe
minimum water coverage is present. Air pockets
in the hydraulic housing or piping system must be
avoided at all costs and must be removed using
a suitable ventilation system and/or placing the
pump at a slight angle (if installed as a portable
pump).Protectthepumpfromfrost.
5.2. Installation methods
• Vertical portable wet well installation with
• Fixeddischargepipelineconnection
• Pressure hose
