Italvibras MVTX 15/7900-G/D 601575 Explosion Proof Screen Vibrator
BRAND : Italvibras
These vibrators are available both in the MVT standard
version and in the MVTX explosion-proof version. They are commonly used on
screens in various industrial sectors and the MVTX version has been designed
for environments with potentially explosive atmospheres with particular
reference to the oil field. MVTX series is characterised by increased thickness
and joints to prevent transmission of an internal ignition source to the
surrounding area.
Technical features
Power supply Three-phase voltage up to 690V (maximum 600V
for cULus), 50Hz or 60Hz (fixed) or 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. Conformity with Standards and Regulations ATEX
Directive 2014/34/UE; EN/IEC 60079-0, EN/IEC 60079-1, EN/IEC 60079-31, UL
674-886, CSA C22.2. See also 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 possible,
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 IP66 according to IEC/EN 60529.
Protection against mechanical impacts IK 08 according to IEC/EN 62262.
Insulation class Class F (155°C). Tropicalization Standard on all screen
vibrators with “drop by drop” trickle system. Ambient temperature From -20°C to
+40°C. Vibrator thermal protection MVTX series equipped with130°C bimetallic
thermal protector or, on request, with130° PTC thermistors. Thermal protection
not included in MVT and MVTX-G series vibrators (available on request). Fixing
of the vibrator Typical horizontal. Lubrication All vibrators are lubricated in
the factory and do not require further lubrication at start-up.
Terminal box Large terminal box to facilitate
electrical connection. The terminal cover, with increased thickness, is
designed to guarantee the seal with flame path joint for MVTX and MVTX-G
series. Electric motor Three-phase asynchronous type.
