centrifugal water pump
PUMP INSTALLATION AND APPLICATIONS
These pumps are suitable for pumping clean water and fluids which are not chemically aggressive to the pump components. They are extremely reliable,economical and simple to use,being particularly suitable for domestic applications such as the automatic distribution of water from small and medium-sized surge tanks, watering gardens,etc .These pumps should be installed in a covered area,protected against the weather. N.B.it is always advisable to install a foot valve or a non-return valve on the suction opening.
OPERATING LIMITS
suction lift up to 9 m
fluid temperature up to 60°C
maximum ambient temperature 40°C
FEATURES
seal mechanical
Attractive design
Low noise, steady performance
No leakage
High concentricity of components
Easy installation, easy maintenance
PERFORMANCE
ample and stable characteristic curves.
outputs having good absolute values and tendencially flat curves.
flat absorption curves at high delivery rates,preventing motor overloading even during prolonged use.
good suction capactities both at low and hight delivery rates.
STRUCTURAL CHARACTERISTICS
cast iron pump body
stainless steel pump body cover
stainless steel mechanical seal(graphite ceramic)
brass impeller with centrifugal radial flow type
protection IP44
with thermal overload protector in single phase motor
