PUMP INSTALLATION AND APPLICATIONS
These pumps are suitable for pumping clean water and fluids which are not chemically aggressive to the pump components.
These pumps are an obvious choice wherever there is a need for high head values hard to reach with single impeller pumps,all thanks to the following features:extremely high outputs,suitable for continuous and heavy-duty use and particularly adaptable to a wide range of particular applications.
2MC series pumps are extremely reliable, simple to use, quiet and virtually maintenance-free, finding many uses in domestic, civil and industrial applications, the automatic distribution of water from surge tanks, watering gardens, increasing the mains supply pressure, feeding boilers, cooling systems and fire-fighting units.
These pumps should be installed in a covered area,protected against the weather.

PERFORMANCE
¡ù particularly ample and stable characteristic curves (high ratio between minimum and maximum head values);
¡ù outputs having high absolute values and tendencially flat curves;
¡ù flat absorption curves at high delivery rates,preventing motor overloading even during prolonged use;
¡ù good suction capacities both at low and high delivery rates.

STRUCTURAL CHARACTERISTICS
¡ù cast iron suction body
¡ù cast iron delivery body
¡ù brass impellers with centrifugal radial flow type
¡ù stainless steel shaft(Hi-Cr plated 45# steel up to 0.75kw)
¡ù stainless steel mechanical seal (graphite to ceramic or graphite to SiC)
¡ù protection IP 44
¡ù with thermal overload protector in single phase motor up to 1.5KW
The remaining single phase motors and all three phase motors require an adequate external motor protector,with connections according to current standards.
¡ù NSK bearing or local bearing

WARRANTY:1 YEAR(according to our general sales conditions)
