ƒ
Ensure ventilation!
Improper use and overstraining leads to damage to the lifting unit. The following appli-
cation limits must be observed:
ƒ
Max. intake/h: 7200 l (1902 US.liq.gal)
ƒ
Max. positive suction head: 5 m (16 ft)
ƒ
Max. pressure in the pressure pipe: 6 bar (87 psi)
ƒ
Fluid temperature: 3 ... 40 °C (37 ... 104 °F), max. 65 °C (149 °F) for 5 min
ƒ
Ambient temperature: 3 ... 40 °C (37 ... 104 °F)
CAUTION
Overpressure in the tank!
If there is overpressure in the tank, it can burst. Observe the following points to pre-
vent overpressure:
• The maximum positive suction head is 5 m (16.5 ft)
• The maximum inlet volume flow must be less than the maximum flow rate at the
duty point!
