Equipment and spare partsBrowse manufacturers Search by manufacturerFounded in 1961 in Italy and part of the global WAMGROUP, OLI S.p.A. is the world's leading manufacturer of industrial vibration equipment, electric motovibrators, and flow aids. We provide direct international deliveries of genuine OLI MVE motovibrators, ATEX explosion-proof units, pneumatic vibrators, silo fluidization systems, and concrete consolidation pokers.
The flagship OLI MVE electric motovibrator series is engineered for continuous heavy-duty industrial operations across screening, conveying, and silo discharge applications. Featuring heavy-duty NiCrMo alloy steel shafts, dynamically balanced rotors, and adjustable eccentric weight plates, MVE motors provide centrifugal forces up to 260 kN across 2-, 4-, 6-, and 8-pole speeds with robust GGG40 ductile iron and aluminum casings.
Certified to strict ATEX, IECEx, and international explosion safety standards, OLI MVE-D and MVE-E flameproof motovibrators operate reliably in hazardous gas and combustible dust zones (Zones 1, 2, 21, 22). The companion MVE-DC direct current line (12V and 24V) is engineered for mobile machinery, concrete transit mixers, salt spreaders, and dump vehicle hoppers.
Compact OLI MVE-MICRO miniature vibrators deliver precise low-force excitation for packaging lines, laboratory sifters, dosing chutes, and pharmaceutical hoppers. The reinforced MVE-SV series is built to endure extreme G-forces and harsh abrasive slurries on heavy industrial vibrating screens and oilfield drilling mud shale shakers.
OLI rotary pneumatic vibrators transform compressed air into powerful high-frequency rotational vibrations. Oil-free turbine vibrators in the OT series generate up to 46,000 vibrations per minute with noise levels under 75 dBA, meeting strict food and pharma hygiene standards. Ball (S series) and roller (OR series) units provide economical, high-force excitation.
OLI linear piston vibrators produce directional sinusoidal oscillations for feeder troughs, screening decks, and packaging conveyors (non-impacting F and K series). For sticky, hygroscopic bulk materials forming internal rat-holes, continuous-impact P series and PS single-impact pneumatic hammers deliver powerful hammer blows to silo walls.
OLI fluidization systems eliminate wall friction and restore fluidity to compressed fine powders in silos and hoppers. Sintered polymer I100 aeration pads inject micro-currents of air into dry powders (cement, lime, flour), while VBS and VBM vibro-aerators combine gentle aeration with high-efficiency silicone membrane vibration to prevent product bridging.
OLI concrete consolidation equipment delivers structural concrete density for precast plants, infrastructure construction, and commercial builds. High-frequency VHN and VHP internal pokers operate at 12,000 VPM powered by safety-isolated 42V / 200Hz electricity. Plug-and-play EWO pokers feature built-in 230V electronic inverters, while CM and FX stations support multiple poker heads.
Engineered for mounting directly onto working attachments of mobile heavy equipment, OLI MVO hydraulic vibrators connect seamlessly to hydraulic circuits on excavators, clamshell buckets, screening crushers, and concrete pump trucks. Delivering up to 3,500 kg of centrifugal force at pressures up to 200 bar, they ensure dependable discharge without electrical supply.
Our technical engineers calculate required vibration parameters based on hopper geometry, wall thickness, and bulk material properties (bulk density, moisture content, angle of repose). We determine the ideal centrifugal force, frequency, and mounting coordinates for OLI MVE electric vibrators or pneumatic flow aids to ensure uninterrupted gravity flow. Structural resonance checks and wall stiffener configurations are fully evaluated to protect plant infrastructure.
OLI vibration technology is widely deployed across mineral processing plants, asphalt and concrete batching facilities, chemical reactors, and food processing lines. We supply heavy-duty OLI-WOLONG W-MVE motors for vibrating screens as well as full-scale silo aeration systems. Proven high reliability in extreme continuous duty minimizes maintenance downtime and protects plant throughput.
All OLI motovibrators are built in automated facilities conforming to ISO 9001 quality management systems. Vacuum-impregnated Class F windings, alloy NiCrMo shafts, oversized spherical bearings, and ductile iron GGG40 castings ensure total reliability under non-stop continuous duty. Rigorous full-load spin tests and dielectric insulation diagnostics are performed prior to dispatch.
We supply genuine OLI products directly from manufacturing facilities in Italy (OLI S.p.A.) and certified industrial production plants in China (OLI Vibrators). All equipment is shipped in reinforced packaging with complete manufacturer inspection records, ATEX explosion-proof certificates, and warranty documentation. Comprehensive international logistics channels ensure dependable door-to-door delivery with transparent customs clearance.
