Operations Necessary For Starting The Diesel Motor Pump - DAB KDN Instrucciones Para La Instalación Y El Mantenimiento

Ensure that the system pipes are independently supported and do not weigh down on the set manifolds so as

to avoid deformation or breaking of any of its components.
3.3. It is advisable to insert vibration-damping couplings when connecting the suction and delivery pipes to the system,
especially when installing Diesel motor pumps.
3.4. Ensure that the characteristics of the water supply source are such as always to guarantee the flow rate
required in the expected operating conditions.
3.5. 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.
e)
Avoid the "siphon" effect at intake: it risks unpriming the pumps!
3.6. The vertical distance between the pump intake and the minimum water level must not exceed 3.2 metres.

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!
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 10.9.9 – UNI 10779).
DAB motor pump sets guarantee 6 hours of autonomy.
b) FILL THE MOTOR WITH LUBRICATING OIL 15 W 40, 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.
3.8. 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.
