3 DESCRIPTION OF THE PRODUCT AND USE:
3.1 Technical and operational features:
The pumps described in this manual have one or more centrifugal impellers installed in series and spinning in a clockwise direction when viewed
from the shaft projection side, axial suction port and radial delivery port (tangential in mod. BHR), equipped with pump shaft borne by oil lubricated
roller bearings and coupled to an electric motor or internal combustion engine by a coupling or drive shaft.
Where possible, specially outfitted pumps can be supplied on request:
- with mechanical seal (...T...) only when coupled to an electric motor;
- with bronze impellers (...H...);
- with stainless steel pump shaft (...Z...);
- with reinforced supports for pulley operation (MEC-ACU...).
Consult the specific technical documentation for further information.
When the product is installed according to the instructions given in this manual and in compliance with the diagrams, the acoustic pressure level issued
by the machine will reach the cautionary values in dB(A) given in the tables in chapter 11 "Technical data".
In particular:
- noise measurement has been conducted in compliance with ISO 3746;
- according to Directive 98/37/EC, the gauging points were 1 meter from the reference surface of the machine and 1.6 meters from ground or access
platform level;
- the maximum value was measured in the electric motor fan side;
- there is a ± 3 dB(A) on the values;
- the pump values were measured in the maximum yield point;
- the electric motor values were measured as the motor idled (or:- the electric motor values are those declared by the manufacturer).
On request, binding noise values can be supplied when the equipment is ordered.
3.2 Fields of use:
The standard version of the product has been designed to pump clear water from sumps or to boost pressure.
3.3 Inadvisable uses: ATTENTION
The standard version of the product is not suitable for:
- dry operation;
