The product is delivered by the manufacturer/shipping agency
in suitable packaging. This normally precludes the possibility of
damage occurring during transport and storage. The packaging
should be stored in a safe place if the location used is changed
frequently.
4.3 Storage
Newly supplied products are prepared that they can be stored
for at least 1 year. The product should be cleaned thoroughly
before interim storage.
The following should be taken into consideration for storage:
- Place the product on a firm surface and secure it against
falling over. Submersible motor pumps should be stored
vertically.
Danger from falling over
Never put down the product unsecured. If the
product falls over,
injury can occur.
- Our products can be stored at temperatures down to -15 °C. The
store room must be dry. We recommend a frost-protected
room with a temperature of between 5˚C and 25˚C for
storage.
- The product may not be stored in rooms where welding
work is conducted as the resulting gases and radiation can
damage the elastomer parts and coatings.
- Any suction or pressure connections on products should be
closed tightly before storage to prevent impurities.
- The power supply cables should be protected against
kinking, damage and moisture.
Beware of electrical current
Damaged power supply cables can cause fatal injury!
Defective cables must be replaced by a qualified
electrician immediately.
- The machine must be protected from direct sunlight, heat, dust,
and frost. Heat and frost can cause considerable damage to
propellers, rotors and coatings.
- The rotors or propellers must be turned at regular intervals.
This prevents the bearing from locking and the film of
lubricant on the mechanical shaft seal is renewed. This also
prevents the gear pinions (if present on the product) from
becoming fixed as they turn and also renews the lubricating
film on the gear pinions (preventing rust film deposits).
Beware of sharp edges
Sharp edges can form on rotors and propellers. There
is a risk of injuries. Wear protective gloves.
- If the product has been stored for a long period of time it
should be cleaned of impurities such as dust and oil deposits
before start-up. Rotors and propellers should be checked
for smooth running, housing coating and damage.
Before start-up, the filling levels (oil, motor filling etc.) of
the individual products should be checked and topped up if
required. Products filled with white oil should be completely
filled before start-up. Please refer to the machine data sheet
for specifications on filling.
Damaged coatings should be repaired immediately.
Only a coating that is completely intact fulfills the
criteria for intended usage.
If these rules are observed, your product can be stored for
a longer period. Please remember that elastomer parts and
coatings become brittle naturally. If the product is to be stored
for longer than 6 months, we recommend checking these
parts and replacing them as necessary. Please consult the
manufacturer.
4.4 Returning to the supplier
Products which are delivered to the plant must be clean
and correctly packaged. In this context, clean means that
impurities have been removed and decontaminated if it has
been used with materials which are hazardous to health. The
packaging must protect the product against damage. If you
should have any questions please contact the manufacturer.
5 Installation
In order to prevent damage to the machine or serious injury
during installation the following points must be observed:
- Installation work – assembly and installation of the machine
– may only be carried out by qualified persons. The safety
instructions must be followed at all times.
- The machine must be inspected for transport damage before
any installation work is carried out .
5.1 General information
After pumping water containing lime, clay or cement, flush out
the machine with clean water in order to prevent encrustation
and to prevent later break-downs.
If you are using level control, make sure that the minimum
water coverage is present. Air pockets may not be allowed to
enter the pump housing or the pipeline system, and they must
be removed with a suitable ventilation system and/or a small
inclination of the machine (with a portable installation). Pro-
tect the machine from frost.
5.2 Installation types
Possible types of vertical installation for the machine:
- Wet installation with a suspension unit.
- Portable wet installation.
5.3 The operating area
The operating area must be laid out for each machine. You
must ensure that lifting gear can be fitted without any trouble,
since this is required for assembly and removal of the machine.
It must be possible to safely reach the machine in its operating
and storage locations using the hoisting gear.
The machine must be located on a firm foundation.
Electric power cables must be laid out in such a way that safe
operation and non-problematic assembly/dismantling are
possible at all times.
The structural components and foundations must be of
sufficient stability to ensure safe and functional operation.
The operator or the supplier is responsible for the provision
of the foundations and their accuracy in terms of dimensions,
stability and strength.
Never let the machine run dry. Therefore, we recommend
installing a level control unit or a dry-run protection system
where there are great variations in the level.
Use guide and defector plates for the pumped fluid intake. If
the water jet reaches the surface of the water or the machine,
air will be introduced into the pumped liquid. This will lead to
unfavorable current and pumping conditions. As a result, the
machine does not run smoothly and is subjected to higher
wear and tear.
5.4 Assembly accessories
Swiveling hoisting gear
The maximum bearing capacity must be greater than the
weight of the machine, add-on units and cable. It is essential
that the machine can be lifted and lowered without hindrance
or endangering personnel. There should be no objects or
obstacles in the swiveling range of the hoisting gear.
Suspension unit (according to the mounting type)
The suspension unit connects to the discharge pipe.
Pump base (according to the mounting type)
The portable pump need a pump base. The pump base is
installed on a firm foundation to keep pump safe.
Fixing materials and tools
Make sure you have the required tools (such as wrenches) and
other material (such as plugs and anchor bolts). The fastening
materials should be sufficiently stable to ensure safe assembly.
5.5 Installation
The following information should be taken into consideration
when installing the machine:
- This work may only be carried out by qualified personnel.
Electrical work may only be carried out by qualified electricians.
- Lift the machine by the handle or lifting eyelets, never by
the power supply cable. When assembling with chains, they
must be connected with a shackle to the lifting eyelets or
the carrying handle. Fastening devices must have official
approval.
- Please observe all guidelines, rules and legal requirements
for working with and underneath heavy suspended loads.
- Wear the appropriate protective clothing/equipment.
- If there is danger that poisonous or asphyxiating gases may
collect, then the necessary counter-measures should be
taken.
- Please also observe all accident prevention guidelines, trade
association safety guidelines and the advice contained in
this operating and maintenance manual.
- The coating of the machine is to be examined before
installation. If defects are found, these must be eliminated.
An intact coating is necessary for the best possible protection
from corrosion.
Wet installation with a suspension unit
A suspension unit must be installed for wet installation. This
must be ordered separately from the manufacturer. The
pipeline system on the discharge side is connected to this.
The connected pipeline must be self-supporting, i.e. it should
not be supported by the suspension unit. The operating area
must be laid out so that the suspension unit can be installed
and operated without difficulty. For maintenance and/or repair
work, the machine must be taken out of the operating area.
The suspension unit makes this possible at any time.
The machine must be completely submerged in pumped
liquid up to the minimum water coverage.
- Install the suspension unit in the operating area (Only use a
suspension unit produced by the manufacturer. Information
about installation is located in the appendix of this
operating manual.).
- Prepare the machine for operation on a suspension unit.
- Check that the suspension unit is firmly fixed and functions
properly.
- Have an expert connect the machine to the power supply
and check the direction of rotation in accordance with
chapter 6.
- Lower the machine slowly onto the guide pipes in the
operating area. Hold the electric power cables slightly taut
when lowering. When the machine is connected to the
suspension unit, make sure that the electric power cables
are secured adequately against falling and/or damage.
- For new installation: Flood the operating area and bleed the
discharge pipe.
- Start the machine in accordance with chapter 6.
