- Install the suction hose in ascending position towards the pump. Do not
install the suction hose beyond the pump height (air bubbles in the suction
hose).
- Install the suction hose so as not to exert any mechanical pressure on the
pump.
- The suction valve must be located at least 30 cm under the fluid level.
- Non-airtight suction hoses suck air and prevent the fluid from being sucked.
-Minimum nominal diameter: 1/2
-Nominal recommended pressure: 10 bar
-Use tubing suitable for functioning under suction pressure.
- Install the delivery hose so as not to exert any mechanical pressure on the
pump.
-Minimum nominal diameter: 2"
-Nominal recommended pressure: 10 bar
During the suction phase, the stop components (nozzles, valves etc.) in the
delivery hose should be fully opened, so that the air in the suction hose is
freely removed.
It is the responsibility of the installer to provide the necessary line acces-
sories to ensure the correct and safe operation of the pump. The accesso-
ries that are not suitable to be used with the previously indicated material
could damage the pump and/or cause injury to persons, as well as causing
pollution.
Loosening of the connections (threaded connections, flanges, gasket seals)
could cause serious ecological and safety problems. Check all the connec-
tions after the first installation and, subsequently, check on a weekly basis.
If necessary, tighten all the connections.
To maximise performance and prevent damage that could affect pump op-
eration, always demand original accessories.
During initial start-up or accidental draining of the pump, fill the oil sump di-
rectly through the suction inlet of the pump. At the end of the operation,
remember to connect the hose to the suction inlet.
When connecting the delivery and suction hoses, use the correct fittings (not
supplied with the unit) with thread seal.
