The double-conical flange VB-E vibrators have been desig-
ned for use in industrial processes in environments with a
potentially explosive atmosphere, caused by gas and dusts,
in compliance with ATEX Directive (94/9/EC).
They are supplied without eccentric weights, which must be
realised and mounted by the Manufacturer of the vibrating
machine. In particular, these vibrators can be used in areas
1 and 2 (gas) and in areas 21 and 22 (dusts) according to the
layout and following features:
Technical features
Power supply
Three-phase voltage from 220V to 690V,
50Hz or 60Hz; suitable for use with an
inverter from 20Hz to the base frequency
with constant torque load profile.
Polarity
4 poles.
Conformity with European Directives
Low Voltage 2006/95/EC,
ATEX 94/9/EC.
Reference Regulations
IEC/EN 60079-0, IEC/EN 60079-7,
IEC/EN 60079-31,
EN 60034-1.
Controls
The components that affect protection
are 100% accurately controlled and
recorded.
Functioning
Continual service (S1) at maximum decla-
red centrifugal force and electric power.
Centrifugal force
Proportioned for a centrifugal force
equal to 5000 Kgf. (49 KN), with eccentric
weights not included, to be made by the
user.
Mechanical protection
IP 66 according to IEC 529, EN 60529.
Protection against mechanical impacts
IK 08 according to IEC 68, EN 50102.
Insulation class
Class F (155°C).
Tropicalization
Standard with “drop by drop” trickle
system.
Ambient temperature
From -20°C to +40°C, on request it is
possible to have vibrators for maximum
ambient temperatures of +55°C in tempe-
rature class T3.
Vibrator thermal protection
On request with PTC rated thermistor
heat detectors 130°C (DIN 44081-44082).
Also on request thermistors with different
temperatures and anti-condensation
heaters.
Fixing of the vibrator
In all positions and therefore without
restriction.
Lubrication
All vibrators are lubricated in the factory
and do not require further lubrication
if used in normal operating conditions
(”FOR LIFE” lubrication). In heavy duty
operating conditions periodical re-lubri-
cation may be applied.
