MVSS
The MVSS stainless steel series vibrators are characterized
by their total protection from liquids, dusts, aggressive
agents and contaminants, thanks to the AISI 304 stainless
steel casing and external components.
Line MVSS-P is available for potentially explosive dust at-
mospheres in conformity with ATEX Directive 94/9/EC.
Power supply
Three-phase voltage from 24V to 690V,
50Hz or 60Hz or single-phase 100-130V
60Hz and 200-240V, 50Hz; suitable for use
with an inverter from 20Hz to the base fre-
quency with constant torque load profile.
Polarity
2, 4, 6 and 8 poles.
Conformity with European Directives
Low Voltage 2006/95/EC.
Reference Regulations
EN 60034-1.
Functioning
Continual service (S1) at maximum decla-
red centrifugal force and electric power.
Intermittent services are also possible
depending on the type of vibrator and the
operating conditions. For detailed infor-
mation, contact our technical assistance
office.
Centrifugal force
Range extended up to 4300 Kgf. (42.4 KN),
with centrifugal force adjustable from 0
to 100%.
Mechanical protection
IP 66 according to IEC 529, EN 60529.
Insulation class
Class F (155°C), class H (180°C) on request.
Tropicalization
Standard on all vibrators, with vacuum
encapsulation up to size 35, with “drop by
drop” trickle system for larger sizes.
Ambient temperature
From -20°C to +40°C. Versions for higher
or lower temperatures are available on
request.
Vibrator thermal protection
Standard PTC rated thermistor heat detec-
tors 130°C (DIN 44081-44082) on size 70,
on request for smaller sizes. 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-lubrication may
be applied to size 35 and larger.
Terminal box
Large fixed electrical connections, with
terminal board cover in stainless steel AISI
304. Special shaped terminals allow to fix
the power supply cable, protecting it from
loosening.
Electric motor
Three-phase and single-phase asynchro-
nous type. Designed for maximum star-
ting torques and torque curves specific to
vibrating machines. Insulated windings
using vacuum encapsulating up to size 35;
using the “drop by drop” trickle system
with class H resin for larger sizes. The rotor
is die cast aluminium.
Casing
In stainless steel AISI 304, with especially
studied design to reduce deposits of dusts
and liquids.
Bearing flange
Constructed in cast iron (spheroidal or
grey) or in aluminium with steel bearing
seat. The geometry of the flange transmits
the load to the casing uniformly.
Bearings
The lower and upper bearings have been
studied to support the relative load and
therefore they have a particular geome-
try, especially designed and made for
Italvibras.
