PUMP INSTALLATION AND APPLICATIONS
These pumps are suitable for handling clean water not containing
abrasive particles and fluids which are not chemically aggressive
to the pump components.
RELIABLE, ECONOMICAL AND SIMPLE TO USE, THEY ARE SUITABLE FOR
INDUSTRIAL APPLICATIONS.
These pumps should be installed in a covered area, protected against
the weather.
PERFORMANCE
The various models in the PQ series are designed to suit
a wide range of applications, with features including:
- high heads achieved from low motor powers.
- small variations in delivery rates in the event of changes
in the pressure demand;
- high tolerance to entrained air in the pumped liquid
STRUCTURAL CHARACTERISTICS
- Cast iron PUMP BODY, with UNI ISO 228/1 gas threaded
suction and delivery ports
- PUMP BODY COVER: brass with front shim disk in stainless
steel
- Aluminum MOTOR BRACKET with brass insert (patented),
reducing difficulties when starting the pump after long periods
without use.
- BRONZE IMPELLER, with radial peripheral blades, floating
on the shaft
- AISI 316 stainless steel MOTOR SHAFT (AISI 416 up to
0.75 kW)
- MOTOR: pumps are coupled directly to an asynchronous,
high efficiency PEDROLLO induction motor, which is quiet running,
closed and externally ventilated, with <IM B3> structural
shape, suitable for continuous duty. 3 Phase 230/400V - 50 Hz
- INSULATION class H
A thermal cutout device (motor protector) is incorporated in
single phase motors.
Three phase motors require an adequate external motor protector
complying with current standards
- PROTECTION IP 55.
- CONSTRUCTION AND SAFETY STANDARDS: complies with EN 60
335 -1, CEI 61-150), EN60034-1), (IEC 34-1, CEI 2-3)
