proper wetting of the pump. The installation of a foot valve is recommended to prevent the emptying of the
suction tube and to keep the pump wet. In this way, the pump will subsequently always start up immediately.
When the system is functioning, the pump can work with pressure at the inlet as high as 0.5bar/7PSI, beyond
which cavitation phenomena can begin, with a consequent loss of flow rate and increase of system noise.
As we have said up to this point, it is important to guarantee low suction pressure by using short tubing of a
diameter equal to or larger than recommended, reducing curves to a minimum and using suction filter of wide
cross-section and foot valves with the lowest possible resistance.
The difference in height between the pump and the fluid level must be kept as small as possible and, at any
rate, within the 2 meters anticipated for the priming phase.
If this height is exceeded, it will always be necessary to install a foot valve to allow for the filling of the suction
tube and provide tubing of wider diameter. It is recommended that the pump not be installed at a difference in
height greater than 3 meters.
ATTENTION!
In the case that the suction tank is higher than the pump, it is advisable to install an anti-siphon valve
to prevent accidental diesel fuel leaks.
Dimension the installation in order to control the back pressure due to water hammering.
