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, quiet and
virtually maintenance-free, finding many uses in domestic and
light commercial applications.
their performance characteristics and low
noise means that cr pumps are particularly suited to water
supply applications (including boosting domestic mains
pressure*) and for large or multiple shower
applications.
These pumps should be installed in a covered area, protected
against the weather.
PERFORMANCE
The working principle of multistage pumps gives high pressures
without excess capacity while retaining the clear advantages of
centrifugal pumps. Pumps in the 2/4CR range have the following
features.
Stable characteristic curves (very high ratio between maximum and
minimum head values);
Very low noise levels at any duty point;
Low power consumption for the head values achieved;
Good suction capacities.
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.
IMPELLERS, centrifugal radial flow type, made of General Electric
Noryl technopolymer (approved for drinking water).
AISI 416 stainless steel MOTOR SHAFT.
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 B.
A thermal cut-out 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.
