JSW2 Self Priming Jet Pump Range General Product Description
PERFORMANCE RANGE
Flow rate up to 80 L/min (4.8 m³/hr)
Dynamic head up to 70 m
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 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.
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
