The MVTX explosion-proof screen
vibrators have been designed for use
in industrial processes in a potentially
explosive atmosphere.
They are used for industrial processes
on screens.
The enclosure of these screen vibrators
is equipped with increased thickness
and joints to prevent the transmission
of an internal explosion to the surroun-
ding area.
Explosion-proof screen vibrators bear
the UL, cUL, ATEX and IECEx markings.
Power supply
Three-phase voltage up to 690V (maxi-
mum 600V for UL and CSA), 50Hz or 60Hz
(fixed) or 20 to 70Hz (variable).
Suitable for use with a variable frequency
drive from 20Hz to the base frequency
with constant torque load profile.
Polarity
4 poles typical. 2, 6, 8 poles are also
available.
Reference Regulations and Directives
See tables.
Controls
The components that affect protection
mode are 100% accurately controlled and
report is recorded for complete traceability.
Functioning
Continuous service (S1) at maximum
declared centrifugal force and electric
power. Intermittent services are also pos-
sible, for detailed information contact our
technical assistance office.
Centrifugal force
Range extended to 7930 Kgf. (77.8 KN),
with centrifugal force adjustable by hand
tools to find better screen performance.
Mechanical protection
Mechanical protection IP66 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 on all screen vibrators with
“drop by drop” trickle system.
Ambient temperature
From -20°C to +60°C.
Vibrator thermal protection
With thermal protector at 130°C for the
entire range, or on request with 130°C PTC
thermistors (DIN 44081-44082). Thermal
protection not installed on MVTX-G series.
Fixing of the vibrator
Typical horizontal.
Lubrication
All vibrators are lubricated in the factory.
Periodic re-lubrication recommended.
Terminal box
Large fixed electrical connections.
The terminal cover, with increased
thickness, is designed to contain
internal explosions.
Electric motor
Three-phase asynchronous type.
Insulated windings using the “drop by
drop” trickle system with Class H resin.
The rotor is die cast aluminum.
Casing
Made in three parts.
Central part in aluminum, external parts in
aluminum or spheroidal cast iron.
Bearing flange
In grey cast iron.
Technical features
4 poles - 1500/1800 rpm
