PERFORMANCE RANGE

Flow rate up to 80 L/min (4.8 m³/h)
Dynamic head up to 72 m

Made from stainless steel for long life, these self-priming pumps incorporate a new hydraulic design which drastically reduces noise levels compared to current standards.

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, LIGHT, ECONOMICAL AND SIMPLE TO USE, FINDING MANY USES IN DOMESTRIC APPLICATIONS, AND IN PARTICULAR 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 JCR series suit a variety of applications.

• high heads with respect to power requirements;
• flat operating and power absorption curves, giving only moderate pressure variations with respect to large variations in delivery demand;
• high tolerance of the presence of entrained air in the fluid to be pumped;
• suction capacities up to 9 metres.

Curve tolerance according to ISO 2548.

STRUCTURAL CHARACTERISTICS

• AISI 304 stainless steel PUMP BODY with UNI ISO 228/1 gas threaded suction and delivery ports.
• AISI 304 stainless steel back plate serving also as mechanical seal housing.
• General Electric® Noryl® GFN2V technopolymer EJECTOR UNIT (approved for drinking water).
• Centrifugal radial flow type IMPELLER in General Electric® Noryl® GFN2V technopolymer (approved for drinking water).
• AISI 416 stainless steel MOTOR SHAFT
• Ceramic and graphite MECHANICAL SEAL.
• MOTOR: 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 B (class F only 0.90 kW single phase).
  A thermal cutout relay (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.
