4.1.1 Hydraulics
Centrifugal hydraulics with different impeller shapes, horizontal flange connection on
the pressure side, inspection cover as well as casing and impeller wear rings.
The hydraulics are not self-priming, in other words, the fluid must flow in either automatically or with supply pressure.
Impeller forms
The individual impeller shapes depend on the size of the hydraulics and not every impeller shape is available for every hydraulic system. The following is an overview of the
different impeller shapes:
▪W = Vortex impeller
▪E = Single-channel impeller
▪Z = Two-channel impeller
▪D = Three-channel impeller
▪V = Four-channel impeller
▪T = Closed SOLID impeller
▪G = Half open SOLID impeller
Product description en
Installation and operating instructions Wilo-EMU FA + FK 17.1, FK 202, FK 34, FK 42 11
Inspection cover (depending on the hydraulics)
Additional opening on the hydraulics housing. This opening is used to remove clogging
in the hydraulics.
Casing and impeller wear rings (depending on the hydraulics)
The suction port and impeller are subjected to the most stress when pumping. In the
case of channel impellers, the gap between the impeller and the suction port is an important factor for a constant delivery rate. The larger the gap between the impeller and
the suction port, the higher the losses in the delivery rate and the risk of clogging increases. In order to ensure long and efficient operation of the hydraulics, an impeller
wear ring and/or casing wear ring is installed depending on the impeller and the hydraulics.
▪Impeller wear ring
The impeller wear ring is attached to the channel impellers and protects the incoming
flow edge of the impeller.
▪Casing wear ring
The casing wear ring is installed in the suction port of the hydraulics and protects the
incoming flow edge in the centrifugal chamber.
The two components can be replaced easily when worn.
4.1.2 Motor
In the three-phase current version, self-cooling submersible motors are used as the
drive. The motor can be used in continuous duty both immersed and non-immersed.
Continuous duty is also possible in dry well installation. The roller bearings are permanently lubricated, which means they are maintenance-free. The connection cable has
bare cable ends and the standard length is 10m. The cable length can be adapted according to the order.
4.1.3 Cooling system
The motor has an active cooling system. For the cooling, the motor is filled with medicinal white oil. The coolant is circulated by an impeller. The impeller is driven by the
motor shaft. The waste heat is transferred directly to the fluid via the cooling flange.
The cooling system itself is not pressurised.
4.1.4 Seal
The seal for the fluid and the motor compartment is made via two mechanical seals. The
two mechanical seals are arranged in two different ways:
▪Version “G”: two separate mechanical seals
▪Version “K”: two mechanical seals in a block seal cartridge made of stainless steel
The sealing chamber between the mechanical seals is filled with medicinal white oil and
accommodates any possible leakage of the mechanical seal on the fluid side.
4.1.5 Material
The following materials are used in the standard version:
▪Pump housing: EN-GJL-250
▪Impeller: EN-GJL-250
▪Motor housing: EN-GJL-250
▪Seal on the motor side: SiC/SiC
▪Seal on the fluid side: SiC/SiC
▪Seal, static: NBR
The precise details of the materials are shown in the respective configuration.

Monitoring of motor compartment
The motor compartment monitoring protects the motor winding from short-circuits.
The moisture is measured by an electrode.
en Product description
12 WILO SE 2017-06
Monitoring of motor winding
The thermal motor monitoring protects the motor winding from overheating. Temperature limiting with bimetallic strip is fitted as standard.
As an option, the temperature can also be measured with a PTC sensor. The thermal
motor monitoring can also be designed as temperature control. This allows the measurement of two temperatures. When the low temperature is reached, an automatic reactivation can be initiated after cooling the motor. When the high temperature is
reached, the unit must deactivate with reactivation lock.
Sealing chamber monitoring
▪FK 17.1, FK 202: The sealing chamber can be equipped with an external pencil elec-
trode.
▪FK 34, FK 42: This sealing chamber is equipped with an internal pencil electrode.
The electrode registers fluid ingress through the mechanical seal on the fluid side. An
alarm or deactivation of the pump can therefore take place through pump control.
Monitoring of motor bearing
The thermal monitoring of the motor bearing protects the roller bearings against overheating. Pt100 sensors are used for temperature measurement.
4.3 Operating modes
Operating mode S1: Continuous duty
The pump can operate continuously at the rated load without exceeding the permissible temperature.
Operating mode: Non-immersed operation
The “non-immersed operation” operating mode describes the possibility of the motor
emerging during the drainage pumping sequence. This allows a further lowering of the
water level as far as the upper edge of the hydraulics. Observe the following points dur-
ing non-immersed operation:
▪Operating mode: Continuous duty (S1).
▪Max. fluid and ambient temperature: The max. ambient temperature corresponds to the
max. fluid temperature shown on the rating plate.
4.4 Operation with frequency converter

caused by falling parts. Loads may not be carried over work places where people are
present!
WARNING
Head and foot injuries due to lack of protective equipment!
Danger of (serious) injuries during work. Wear the following protective equipment:
• Safety shoes
• Safety helmet must be used if lifting equipment are used!
NOTICE
Only use lifting equipment in a technically sound condition!
Only use lifting equipment in a technically sound condition for lifting, lowering and
transporting the pump. Ensure that the pump does not become jammed during lifting and lowering. Do not exceed the max. permissible bearing capacity of the lifting
equipment!
Only remove the outer packaging at the place of utilisation to ensure that the pump is
not damaged during transport. Use tear-proof plastic sacks of sufficient size to package used pumps for transport in a leak-proof manner.

Fig.2: Attachment point
▪Adhere to the applicable national safety regulations.
▪Use legally specified and approved lifting gear.
▪Select the lifting gear based on the existing conditions (weather, attachment point,
load, etc.).
▪Only attach the lifting gear to the attachment point. Fix with a shackle.
▪Use lifting equipment with sufficient bearing capacity.
▪The stability of the lifting equipment must be ensured during operation.
▪When using lifting equipment, a second person must be present to coordinate the pro-
cedure if required (e.g. if the operator’s field of vision is blocked).
5.3 Storage
DANGER
Danger due to fluids hazardous to health!
If the pump is used in fluids hazardous to health, decontaminate the pump after dismantling and before carrying out any other work! There is danger to life! Observe the
specifications in the work regulations! The operator must make sure that the personnel has received and read the work regulations!
WARNING
Sharp edges on the impeller and suction port
Sharp edges can form on the impeller and suction port. There is danger of limbs being cut-off! Protective gloves must be worn to protect from cuts.
CAUTION
Total damage due to moisture ingress
Moisture ingress in the power supply cable damages the power supply cable and the
pump! Never immerse the end of the power supply cable in a fluid and firmly seal it
during storage.
Newly supplied pumps can be stored for one year. Contact customer service to store
the pump for more than one year.
The following must be observed for storage:
▪Securely position the pump on a firm bearing surface. Store pumps with pump support
foot in an upright position, store pumps without pump support foot in a horizontal pos-
ition. Secure the pump against falling over and slipping!
▪The max. storage temperature is -15°C to +60°C at a max. relative humidity of 90%,
non-condensing. Frost-proof storage at a temperature of 5°C to 25°C with relative
humidity of 40% to 50% is recommended.
▪Do not store the pump in rooms in which welding work is carried out. The resulting
gases or radiation can corrode the elastomer parts and coatings.
▪Seal the suction and pressure connection tightly.
▪Protect power supply cables against kinking and damage.
▪Protect the pump from direct sunlight and heat. Extreme heat can cause damage to the
impellers and the coating!
▪Impellers must be turned by 180° at regular intervals (3–6months). This prevents
jamming of the bearings and renews the lubrication film of the mechanical seal. WARN-
ING!There is a risk of injury due to edges on the impeller and suction port!
▪Elastomer parts and the coating are subject to natural brittleness. Contact customer
service if the pump must be stored for more than 6months.
After storage, remove any dust and oil from the pump and check the coating for dam-
age. Repair damaged coatings before further use.

ance with EN50110-1).
▪Installation-/dismantling: The technician must be trained in the use of the necessary
tools and mounting materials for the relevant construction site.
6.2 Installation types
▪Vertical stationary wet well installation with suspension unit
▪Vertical portable wet well installation with pump support foot
▪Vertical stationary dry well installation
▪Horizontal stationary dry well installation
NOTICE!Horizontal installation is not possible, depending on type and performance.
For this installation type, contact customer service!
6.3 Operator responsibilities
▪Observe locally applicable accident prevention and safety regulations of trade associ-
ations.
▪Observe all regulations for working with heavy loads and under suspended loads.
▪Provide protective equipment and ensure that the protective equipment is worn by
personnel.
▪Observe local sewage technology regulations for the operation of sewage systems.
▪Avoid pressure surges!
Pressure surges can occur in long discharge pipelines with steep terrain. These pressure
surges can lead to the destruction of the pump!
▪Ensure the cooling time of the motor depending on the operating conditions and the
size of the pump chamber.
▪Structural components and foundations must be of sufficient stability in order to allow
the device to be fixed securely and functionally. The operator is responsible for the pro-
vision and suitability of the structural component/foundation!
▪Check that the available consulting documents (installation plans, design of the operat-
ing space, inflow conditions) are complete and correct.
