WORKING PRINCIPLE

Thr\e series consists of PUMPS with a SINGLE CENTRIFUGAL  IMPELLER.These pumps have an essential form are the result of precise design choice,made to obtain specific performance characteristics.The impeller,mounted on the end of the motor shaft,directly faces the suction opening machined in the pump.The shape of impeller channel transfer energy to the fluid both in the form of pressure and an increase in speed.After leaving the fluid passes to the volute and tapered diffuser which transform part of the kinetic energy energy into pressure energy.

PUMP INSTALLATION AND APPLICATIONS

These pumps are suitable for handing clean and fluids which are not chemically aggressive to the pump components.

THE ARE EXTREMELY RELIABLE,SIMPLE TO USE,QUIET AND VIRTUALLY MAINTANCE-FREE,FINDING MANY USES IN DOMESTIC AND CIVIL APPLICATIONS,AND IN PARTICULAR THE AUTOMATIC DISTRIBUTION OF WATER FRO,SMALL AND MEDIUM-SIZE SURGE TANKS,TRANSFERRING WATER,WATERING GARDENS,ECT.

These pumps should be installed in a covered area,protected against the weather.

PERFORMANCE

The range of pumps making uo he series is particularly varied:however when developing the single units,care was taen to aim at standardizing the following features within the series:

-Ample and stable characteristic curves

-outputs having food absolute values and tendencially flat curves:

-Flat absorption curves at high delivery rates,preventing motor over loading even during prolonged use;

-Good suction capacities both at low and high delivery rates

STRUCTURAL CHARACTERISTICS

cast iron PUMP BODY

stainless stell PUMP BODY COVER,in cast iron on more powerful model.

BRASS IMPELLER,with radial peripheral blades,floating on the shaft.

Ceramic and graphite MECHANICAL SEAL.

MOTOR :the pumps are coupled directly to an asynchronous,high efficiency TOP induction motor of suitable size,which is quiet running,closed and externally vebtilated,suitable for continuous duty.INSULATION class F(B up to 0.75kw)

the thermal cutout relay(motor protector) is incorporated in single phase motors.

Three phase motors require an adequate external motor protector,with connections according to current standards.

PROTECTION IP44

CONSTRUCTION AND SAFETY STANDARDS in compliance with IEC.

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