Explosion proof vibrator CDX

Specifications of vibrators CDX


The CDX explosion-proof vibrators have been designed for use in industrial processes in a potentially explosive atmosphere. The enclosure of the CDX vibrators is equipped with increased thickness and joints to prevent the transmission of an internal explosion to the surrounding area. The CDX series is characterized and enhanced by many different certifications, depending on the vibrator model.

Power supply

Three-phase voltage from 24V to 690V (limit at 600V for UL and CSA certifications), 50Hz or 60Hz, or single-phase 100-130V 60Hz and 200-240V 50Hz; suitable for use with a PWM inverter from 20Hz to the base frequency with constant torque load profile.


2, 4, 6 and 8 poles.


The components that affect protection are 100% accurately controlled and recorded.


Continual service (S1) at maximum declared centrifugal force and electric power. Intermittent services are also possible depending on the type of vibrator and the operating conditions. For detailed information, contact our technical assistance office.

Centrifugal force

Range extended to 22400 Kgf. (220 KN), with centrifugal force adjustable from 0 to 100%.

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).


Standard on all vibrators, with vacuum encapsulation up to size 35, with “drop by drop” trickle system for larger sizes.

Ambient temperature

From -10°C to +40°C.

Vibrator thermal protection

With thermal protector at 130°C for the entire CDX range, or on request with PTC thermistors rated heat detectors 130°C (DIN44081-44082).

Fixing of the vibrator

In all positions and therefore without restriction.


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 40 and larger.

Terminal box

Large fixed electrical connections. The terminal cover, with increased thickness, is constructed to contain internal explosions. Special shaped terminals allow to fix the power supply cable, protecting it from loosening.

Electric motor

Three-phase and single-phase asynchronous type. Designed for maximum starting torques and torque curves specific to requirements of the vibrating machines. Insulated windings using vacuum encapsulating up to size 35; using the “drop by drop” trickle system with Class H resin for the larger sizes. The rotor is die cast aluminium.


In high-tensile aluminium alloy up to size 30, in spheroidal cast iron for larger sizes. Patented shape that improves heat dispersion and lowers normal running temperature with full load. An external earthing screw is located on the casing as prescribed by Regulation IEC/EN 60079-0.

Bearing flange

Constructed in spheroidal or grey cast iron. The geometry of the flange transmits the load to the casing uniformly.


Custom made with particular geometry, especially designed for this vibrator, suitable to support both high radial and axial loads.

Motor shaft

In treated steel alloy (Isothermic hardening) resistant to stress.

Eccentric weights

Allow continual adjustment of the centrifugal force. This adjustment is realized by a graduated scale, which expresses the centrifugal force as a percentage of the maximum centrifugal force. A patented system (patent N° MO98A000194), called ARS, prevents adjustment errors.

Weight covers

In aluminium alloy.


Electrostatic surface treatment based on polymerised epoxy polyester powder in oven at 200°C. Tested in salt spray for 500 hours.

Other features

The CDX series is supplied without cable gland and with NPT threaded conduit opening.
