PERFORMANCE
The range of pumps making up the DK series is particularly varied: however when developing the single units, care was taken to aim at standardizing the following features within the series:
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 capacities both at low and high delivery rates
-Non jam impeller for pumping dirty or sandy water
PERFORMANCE RANGE
Flow rate up to 340 l/min (20.4 M3/H)
Dynamic head up to 20m
OPERATING LIMITS
Suction lift up to 7 m
Fluid temperature up to + 80℃
Maximum ambient temperature +40℃
 
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, simple to use, quiet and virtually maintenance-free, finding many uses in domestic and civil applications, and in particular the automatic distribution of water from small and medium-size surge tanks, transfer water,Watering gardens, etc.
These pumps should be installed in a covered area. protected against the weather.
WARRANTY: 1 YEARS
(according to our general sales conditions).
STRUCTURAL CHARACTERISTICS
PUMP BODY Cast iron
FRONT COVER Cast iron
IMPELLER Brass or cast iron
MECHANICAL SEAL Ceramic and graphite
MOTOR:
The pumps are coupled directly to an asynchronous, high efficiency SILVER ELEPHANT induction motor of suitable size, which is quiet running, close and extremely ventilated, suitable for continuous duty.
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.
INSULATION Class B
PROTECTION IP44
CONSTRUCTION AND SAFETY STANDARDS in compliance with IEC.
