PRODUCT DESCRIPTION

3. Product description
The lifting unit has been manufactured with great
care and is subject to constant quality controls.
Trouble-free operation is guaranteed if the device
is installed and maintained correctly.

3.1. Intended use and fields of application

DANGER of explosion!
Gas can collect in the collection reservoir
during pumping of sewage containing faeces.
This can ignite and lead to an explosion as a
result of incorrect installation and operation.
• The collection reservoir must be undamaged
(no cracks, leaks, porous material)!
• The inlet and outlet as well as the vent must
be connected in accordance with the regula-
tions and be absolutely leak-tight!
DANGER – explosive fluids!
It is strictly prohibited to pump explosive flu-
ids (gasoline, kerosene etc.). The lifting units
are not designed for these fluids!
Pumping of untreated sewage that cannot be
returned to the sewer system using natural falls,
and for the draining of objects that are below
the backflow level (according to DIN EN 12056/
DIN 1986-100).
The lifting unit must not be used for pumping
• Debris, ash, garbage, glass, sand, plaster, cement,
lime, mortar, fibrous materials, textiles, paper
towels, wet-wipes (e.g. fleece cloths, moist toilet
paper wipes), nappies, cardboard, coarse paper,
synthetic resins, tar, kitchen waste, grease, oil
• Slaughterhouse waste, disposal of slaughtered
animals and animal waste (liquid manure, etc.)
• Toxic, aggressive and corrosive substances, such
as heavy metals, biocides, pesticides, acids, bases,
salts, swimming-pool water
• Cleaning agents, disinfectants, dishwashing or
laundry detergents in excess amounts, and such
which have a high degree of foam formation
• Sewage from drainage objects that are located
above the backflow level and can be drained by
natural fall (in accordance with EN 12056-1)
• Explosive media
• Drinking water
The system must be installed in accordance with
the general rules as detailed in EN 12056 and
DIN 1986-100.
Intended use includes compliance with this man-
ual. Any other use is regarded as non-compliant
with the intended use.

3.1.1. Application limits

DANGER due to overpressure
Exceeding the application limits can result in
excessive pressure in the collection reservoir
in the event of system malfunction. This can
cause the collection reservoir to burst! There
is a health risk due to contact with sewage
polluted by bacteria (faeces). Always comply
with the application limits and ensure that the
inlet is blocked if the system malfunctions.
Installation and operating instructions Wilo-EMUport CORE
The following application limits must be observed
strictly:
• Max. inlet:
• CORE 20.2: 20 m³/h
• CORE 45.2: 45 m³/h
• CORE 50.2: 50 m³/h
• CORE 60.2: 60 m³/h
• Max. reservoir flooding:
• CORE 20.2: 5 m for max. 3 h
• CORE 45.2, 50.2, 60.2: 6,7 m for max. 3 h
• Max. permitted pressure in the system pressure
pipe: 6 bar
• Max. fluid temperature: 40 °C
• Max. ambient temperature: 40 °C

3.2. Set-up

The Wilo-EMUport CORE is a submersible and
fully automatically operating sewage lifting unit
with solids separation system and two sub-
mersible sewage pumps in alternating operation
without peak-load operation.

3.2.1. Solids separation system
Solids separation system with all-in-one gastight
and watertight collection reservoir without con-
structive welded joints, as well as two separately
blockable solids separation reservoirs.
The collection reservoir has rounded edges, the
tank bottom is bevelled, the deepest point is
located directly below the pump. This prevents
deposits and the drying of solids at critical points.
With pre-filtering in the solids separation reser-
voirs, the solids are filtered from the fluid and only
pre-filtered sewage is directed to the collection
reservoir.
3.2.2. Sewage pumps
Pumping is performed by two high-performance
submersible sewage pumps in dry well instal-
lation. The pumps are designed as a redundant
system and run in alternating operation.
Simultaneous operation of the two pumps is
strictly forbidden!

3.2.3. Level control

The level control is controlled by a level sensor.
Measurement range is documented on the rating
plate.
