PUMP INSTALLATION AND APPLICATIONS
These pumps are suitable for handling 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 DOMESTRIC 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.
PERFORMANCE
The wide range of pumps in the JSW series suit a variety of applications.
- high heads with respect to power requirements;
- flat operating and power absorption curves, giving moderate curve variations with respect to large variations in delivery demand;
- high tolerance of the presence of entrained air in the pumped liquid;
- suction capacities up to 9 meters.
- Curve tolerance according to ISO 2548.
STRUCTURAL CHARACTERISTICS
- Cast iron PUMP BODY with UNI ISO 228/1 gas threaded suction and delivery ports, threaded side openings for installing a pressure gauge and pressure switch.
- Pump BACKPLATE in AISI 304 Stainless Steel (Cast Iron on JSW 3 models)
- General Electric® Noryl® GFN2V technopolymer EJECTOR UNIT (approved for drinking water).
- BRASS IMPELLER centrifugal radial flow type.
- AISI 416 stainless steel MOTOR SHAFT (AISI 316 on JSW 3 models, optional on others)
- Ceramic and graphite MECHANICAL SEAL.
- MOTOR: the pumps are coupled directly to an asynchronous, high efficiency PEDROLLO induction motor of suitable size which is quiet running, closed and externally ventilated, suitable - for continuous duty. INSULATION class F (Class B below 0.75kW).
- A thermal cutout device (motor protector) is incorporated in single phase motors.
Three phase motors require an adequate external motor protector connected according to current standards.
- PROTECTION IP 44.
- CONSTRUCTION AND SAFETY STANDARDS in compliance with EN 60 335-1 (IEC 335-1, CEI 61-150) EN 60034-1 (IEC 34-1, CEI 2-3).
- REGISTERED MODEL.
NOTE: It is always advisable to install a foot valve on installations that involve a suction lift.
