4 Description of the pump The Stratos GIGA2.0 high-efficiency pump is a glanded pump with integrated power
adjustment and “Electronic Commutated Motor” (ECM) technology. The pump is con-
figured as a single-stage low-pressure centrifugal pump with flange connection and
mechanical seal.
The pump can be installed both directly as pipe installation pumps in sufficiently se-
cured pipes or be placed on a foundation base. Mounting brackets (accessories) are
available for installation on a foundation base.
The pump housing is designed as an in-line design; i.e. the flanges on the suction and
pressure side are on one axle. All pump housings are provided with pump support feet.
Installation on a foundation base is recommended.
NOTICE
Blind flanges (accessories) are available for all pump types/housing sizes from the
Stratos GIGA2.0-D series. When replacing the motor impeller unit (motor with im-
peller and electronic module), a drive can thus remain in operation.

kW, EMC irregularities can occur under unfavourable circumstances when used in resid-
ential environments (C1) with low electrical power in the conducted range. In this case,
please contact WILO SE so that together we can find a quick and suitable shutdown
measure.

Fluids
Water-glycol mixtures or fluids with a different viscosity than pure water increase the
power consumption of the pump. Only use mixtures with corrosion protection. Observe
the relevant manufacturer’s specifications!
ƒThe fluid must be sediment-free.
ƒWilo’s approval must be obtained for the use of other fluids.
ƒMixtures with a proportion of glycol of >10% influence the Δp-v characteristic
curve and the flow calculation.
ƒThe compatibility of the standard seal/standard mechanical seal with the fluid is
generally given under normal system conditions.
Special circumstances may require special seals, for example:
–solids, oils or EPDM-attacking substances in the fluid,
–air content in the system, etc.
Observe the safety data sheet for the fluid to be pumped!
NOTICE
When using water-glycol mixtures, the use of an S1 variant with a corresponding
mechanical seal is generally recommended.

5 Transport and storage
5.1 Shipping The pump is secured to a pallet ex works, packaged in a box and protected against dirt
and moisture.
5.2 Transport inspection Check delivery immediately for damage and completeness. Defects must be noted on
the freight documentation! Defects must be notified to the transport company or the
manufacturer immediately on the day of receipt of shipment. Subsequently notified de-
fects can no longer be asserted.
Only remove the outer packaging at the place of utilisation to ensure that the pump is
not damaged during transport.
5.3 Storage
CAUTION
Damage due to incorrect handling during transport and storage!
Protect the product from moisture, frost and mechanical damage during transport
and temporary storage.
Leave stickers on the pipe connections so that no dirt and other foreign matter can get
into the pump housing.
Fig.5: Turning the shaft
To prevent scoring at the bearings and sticking, turn the pump shaft once a week using
a socket wrench (see Fig.5).
If a longer storage time is required, contact Wilo for preservation measures.
WARNING
Risk of injury due to incorrect transport!
If the pump is transported again at a later date, it must be packaged so that it cannot
be damaged during transport. Use the original packaging for this, or choose equival-
ent packaging.
Damaged transport lugs can break off and cause considerable personal injury. Check
the transport lugs before use for damage and secure fixation.
5.4 Transport for installation/dis-
mantling purposes
Fig.6: Lifting direction

en Installation
20 WILO SE 2021-12
The pump must be transported using approved lifting gear (hoist, block and tackle,
etc.). The lifting gear must be attached to the transport lugs at the motor flange. Slide
the lifting loops under the adapter plate, if necessary (Fig.6).
WARNING
Damaged transport lugs can break off and cause considerable personal
injury.
• Check the transport lugs before use for damage and secure fixation.
NOTICE
To improve the weight distribution, the transport lugs can be swivelled/rotated ac-
cording to the lifting direction.
To do so, loosen and then re-tighten the fastening screws!
DANGER
Risk of fatal injury from falling parts!
The pump itself and pump parts can be extremely heavy. Falling parts pose a risk of
cuts, crush injuries, bruises or impacts, which can be fatal.
• Always use suitable lifting equipment and secure parts against falling.
• Never stand underneath a suspended load.
• During storage and transport, as well as before all installation and assembly work,
ensure that the pump is in a safe position and standing securely.
WARNING
Personal injury due to unsecured installation of the pump!
The base with the threaded holes is used for fixation only. When standing freely, the
pump might not be sufficiently stable.
• Never place the pump unsecured on the pump support feet.
CAUTION
Improper lifting of the pump by the electronic module can cause damage
to the pump.
• Never lift the pump by the electronic module.
