WARNING
• For applications where the pump uses a cardan shaft, strain on the pump shaft must be avoided
caused by incorrect use of the cardan shaft (poor lubrication of moving parts, incompatible
turning radius for type of cardan shaft used).
• In case of use at very low temperatures, check that ice does not form inside the pump.
• Complete all routine maintenance, especially concerning the oil.
5.2 HYDRAULIC CONNECTIONS
fi«
CAUTION
• Do not connect up to the mains supply of drinking water.
• All pipes must be securely fixed to the relative coupling with grips.
WARNING
• The intake of the pump must use a tank at atmospheric pressure and the level of the liquid must
be between 1m / 3.3ft above and 1 m /3.3 ft below the intake coupling (see fig. 8); never connect
the pipe to pressurized water pipes.
• For periods of 10÷15 min, the intake of the pump can operate at drops of up to 3m/ 9.8 ft: it must
not operate at drops in excess of this.
• The pump must be provided with an adequate intake filter. In case of doubt, contact a Skilled
Technician. Check that the filter is perfectly clean at all times.
• The internal diameter of the intake and bypass pipes must be equal to the external diameter of
the intake and bypass couplings respectively. They must have a nominal pressure of 10 bar /145
psi
• The internal diameter of the delivery pipes must be equal to the external diameter of the delivery
couplings. Their nominal pressure must not below the maximum pressure of the pump.
• Do not supply the pump with water at a temperature in excess of 40°C/104°F or below 5°C/
41°F.
• Do not operate the pump for a long time if it is not connected to a water supply.
• Do not supply the pump with salt water or water containing impurities. In this event, run the
pump for a few minutes with clean water.
