4.1.3. Spare Parts
Please refer to the technical drawing of the pump for necessary spare
parts.
4.1.4. Shaft
The pumps are provided with the rigid shaft capable of supporting
different loading conditions. Since the shaft diameter is highly resistant to
bending and the distance between the bearing and the sealing is short,
pump can operate at optimal conditions for the sealing.
4.1.5. Bearing and Lubrication
Lifelong grease lubricated bearings are used in ENDURO series
submersible pumps. There is no need any extra lubrication for bearings.
On the side of the pump and motor side 3300/6300 series bearings can
be used
.
4.1.6. Seals
Special Stuffing Box Design*
Spiral grooves in the big conical seal chamber avoid contamination of the
sealing environment with solids improved mechanical seal life.
*Available on some models.
Shaft Sealing
To prevent water pass to motor two sets of mechanical seals with oil bath
in the middle of these seals are used.
In standard production, SiC-SiC mechanical seals are used for sealing.
Water Leakage Warning System
An electrode system is used in case of water leakage caused by worn out
mechanical seal or any other reason.
4.1.7. Drive
MASDAF ENDURO Series Submersible sewage pumps are developed
for the purpose of pumping domestic and industrial waste water
containing large solid particles. These pumps are suitable for operating
entirely immersed in water. Different types of impeller are used in
ENDURO Series pumps for different purposes of pumping clean and
waste water, sewage containing solids and fibrous materials and sludge.
5. TRANSPORT AND STORAGE
Suction, discharge and all auxiliary fittings must be closed during
transport and storage. Flange covers must be removed while the pump
unit is being installed.
5.1. Transport
Pump and pump group must be carried safely to the installation location
by lifting equipments.
CAUTION
Current general lifting safety instructions must be applied. Please use a
suspension system shown in figure while you are carrying and lifting the
pump unit. Prefer fabric cable for suspension.

Transport of Pump Group
Incorrect lifting may damage the pump unit and cause injuries
Damages caused in transport.
Check the pump when it is delivered to you. Please let us know of there is
any damage.
5.2. Storage
Please keep the unit clean and dry area during storage.
If the pump is out of use for a long time, please consider the instructions
below.
1.
If there is water inside the pump, drain it.
2.
Clean the pump casing and impeller by jetting clean water for a short
time.
3.
Empty water inside the pump casing, suction line and discharge line.
4.
Spray an anti-corrosive into the pump casing.
5.
If the pump is not operated immediately, it has to be kept in clean and
dry area in vertical position.
6. ASSEMBLY / INSTALLATION
6.1. Connection Type
i. Suspended Connection:
The pump is hanged to the inlet of the pipe
system on the ground by a special connecting device. Pump does not
sit on the base of the sump. If required, the connection elbow can be
used as a non-return valve. Steel discharge pipe between the pump
and suspension part keeps the pump on suspension. Suspended
connection can apply on 50-160, 50-200 (up to 5,5 kW) and 80-190
types.At suspended connection option,it should be noted that these
pumps enables to operate more reliably by not bringing overload to
the discharge pipe because of being lighter.It is not necessary for
sump bottom to be flat and solid for suspended connection.
Suspension elbow and complete suspension set are needed for this
application.
