Operations Necessary For Starting The Diesel Motor Pump; 6.8. Diesel Motor Pump Exhaust Gases - DAB 1 KVT Instrucciones Para La Instalación Y El Mantenimiento

6.4. Make the intake section following all the precautions necessary to keep load losses to a minimum and to avoid the
formation of air pockets, for example:
a) Position the set as close as possible to the water supply source.
b) Provide each pump with its own intake pipe (EN 12845 – UNI 10779).
c) Lay the suction pipes horizontally or sloping slightly upwards towards the set.
d) Avoid using elbows or couplings that cause sudden changes in direction. If necessary, use bends with a wide radius.

OPERATIONS NECESSARY FOR STARTING THE DIESEL MOTOR PUMP

ALL THE DIESEL MOTOR PUMP SETS ARE DELIVERED DRY, WITHOUT DIESEL FUEL,
MOTOR OIL AND COOLING FLUID!
THE SET MUST NOT BE STARTED UNTIL IT HAS BEEN FILLED WITH DIESEL FUEL,
MOTOR OIL AND COOLING FLUID!
6.6. IF THE FIRST START-UP OF THE DIESEL MOTOR PUMP SET IS CARRIED OUT MORE
THAN 6 MONTHS AFTER THE INSPECTION DATE, SPECIAL MAINTENANCE MUST BE
PERFORMED (AS SPECIFIED IN THE MANUAL OF THE DIESEL MOTOR IF SUPPLIED
WITH THE MOTOR PUMP) BEFORE STARTING THE SET FOR THE FIRST TIME, SO AS TO
ENSURE THAT THERE IS NO DAMAGE CAUSED BY THE LONG PERIOD OF INACTIVITY.
a) Fill the tank of the Diesel motor pump with diesel fuel up to the maximum level to ensure 3-4-6 hours of autonomy
depending on the risk classes of the system (EN 12845 point 10.9.6 – UNI 10779).
DAB motor pump sets guarantee 6 hours of autonomy.
b) FILL THE MOTOR WITH LUBRICATING OIL, as indicated in the table below (check the level of the
motor lubricating oil with the dipstick provided).
c) Fill the air suction filter with special oil according to the instructions supplied with the Diesel motor

DAB reserves the right to change motors or their parts without notice; reference should therefore always be made to
the manual of the Diesel motor supplied with the motor pump.
6.7. Though the Diesel motor pump is more reliable than the electropump (it works even during a black out), it needs
particular precautions to avoid excessive noise, vibrations, contamination by exhaust gas, overheating.
Below are listed some measures to adopt to obtain maximum efficiency during operation.

6.8. DIESEL MOTOR PUMP EXHAUST GASES

Convey the exhaust gases outside the pump room using a specific pipeline (not supplied) connected to the silence
exhaust pipe supplied with the Diesel motor pump.
La tubazione di scarico può correre lungo il soffitto od il pavimento.
The exhaust pipe can run along the ceiling or the floor.
It must be protected against unfavourable weather conditions and provided with drainage for emptying any condensate.
To avoid exceeding the maximum value of back pressure at discharge (600 mm H2O for air-cooled motors and 100 mm
H20 for supercharged air-cooled motors), it is also recommended to adopt the following measures:

Preferably, the exhaust pipeline should not be more than 10 metres long.

If the exhaust pipeline is no more than 10 metres long, its diameter can be the same as or larger than the diameter of
the exhaust pipe of the Diesel motor.

If the exhaust pipeline is more than 10 metres long, its diameter must be the same as the diameter of the motor
exhaust pipe (in mm) multiplied by the length of the pipeline (in metres), divided by 8.
For example: 12 metre pipelines with Diesel engine exhaust pipe of 45 mm = (45 mm X 12 m):8 = 68 mm. The
pipeline, 12 metres long, must therefore be at least 68 mm in diameter.
Reduce as much as possible the number of bends used in the pipe (maximum 6) and opt for the use of bends with a

wide radius.
