ATTENTION! It is the installer's responsibility to use tubing with adequate characteristics.
The use of tubing unsuitable for use with diesel fuel can damage the pump, injure persons and cause
pollution.
Loosening of the connections (threaded connections, flanging, gasket seals) can cause serious ecological
and safety problems.
Check all the connections after the initial installation and on a daily basis after that.
Tighten the connections, if necessary.
4.5.1- Connecting the suction line (not supplied)
Minimum recommended nominal diameter: 1".
Nominal recommended pressure: 10 bar.
Use tubing suitable for functioning under suction pressure
The suction hose (not supplied) must have a minimum diameter of 25 mm and must be rigid and kink
resistant to prevent crushing and suitable for vacuum..
The assembly connections must be sealed with hemp and Teflon or thread sealing tape so that the sealing
is perfect.
For fittings equipped with gaskets or O-rings, it is not necessary to add Teflon or sealing tape.
Check the correct sealing over time.
Do not forget to check the connections of the strainer (mounted with Teflon). Add clamps if necessary.
In any case, the suction hose must not be directed upwards.
The suction line should be as short as possible, since the suction capacity decreases as the length of the
line increases.
The suction line should ascend steadily towards the pump to prevent air pockets.
Sufficient liquid supply must be assured; the end of the suction line must always be in liquid.
The suction line must be installed so that it does not exert any mechanical force or tension on the pump.
If the conveying medium is contaminated, a suction filter must be used to protect the pump from sand and
dirt
IMPORTANT! It is recommended to install a check valve.
Before starting, carefully check the suction hose to make sure that it is properly sealed. Air bubbles in the
suction line are an indication that there may be a leakage!
4.5.2- Connecting the discharge line (not supplied)
Minimum recommended nominal diameter: 1"
Nominal recommended pressure: 10 bar
The discharge hose (not supplied) must have a minimum diameter of 25 mm and must be rigid and kink
resistant to prevent crushing.
To avoid leakages in the delivery line and get the best performance, ensure to seal the fittings with
Teflon.
Remarks:
- All components of the pressure line must be compression-proof.
- All components of the pressure line must be professionally installed
- If the components are not compression-proof or if they are improperly installed, the pressure line could
burst during operation. Risk of injury from liquid spurting out!
