ZOOMRY
ZOOMRY motorized pulleys are compact, hermetically sealed conveyor drive units that integrate the motor, gear reducer, and bearings inside a single pulley shell. This all-in-one design eliminates the need for external motors, couplings, chains, and exposed drive components — making it the ideal space-saving solution where conventional drives are impractical. Completely impervious to water, oil, grease, dust, and other contaminants, motorized pulleys excel in demanding environments across mining, cement, steel, food processing, and recycling industries.

Why Choose a Motorized Pulley Over a Conventional Drive?
Conventional conveyor drive systems require external motors, gearboxes, couplings, belt guards, and mounting foundations — each a potential point of failure and a demand on valuable space around the conveyor. A motorized pulley condenses all these components into a single sealed unit inside the pulley drum, freeing up floor space, simplifying installation, and dramatically reducing maintenance requirements.
The comparison is clear: a conventional drive setup occupies up to 3x the lateral space beside the conveyor and exposes motors to dust, moisture, and physical impact. A motorized pulley achieves the same drive power within the pulley diameter itself — requiring zero external footprint beyond the conveyor frame. With IP66-equivalent hermetic sealing, the internal components are permanently protected from the operating environment, eliminating the need for motor guards, drip covers, or climate-controlled enclosures.
Where Are Motorized Pulleys Used?
Motorized pulleys are the preferred drive solution for applications where space, hygiene, or environmental exposure rule out conventional drive arrangements:
- Food Processing & Wash-Down Environments — the smooth, sealed drum surface has no crevices for bacteria or contaminants to accumulate. The stainless steel shell option meets USDA and HACCP hygiene requirements for meat, dairy, grain, and packaged food conveyors.
- Underground Coal Mining — explosion-proof motorized pulleys eliminate exposed electrical components in gassy environments. The sealed design prevents coal dust ingress, and the compact form fits within restricted tunnel cross-sections where conventional motor-and-gearbox assemblies simply cannot fit.
- Port Terminals & Coastal Installations — the hermetic seal prevents salt-laden air and moisture from corroding internal motor windings and bearings, extending service life in marine environments to 50,000+ hours.
- Recycling & Waste Handling — impervious to dust, liquids, and abrasive particles that would quickly destroy exposed drive components in sorting lines and shredder feed conveyors.
- Mobile Equipment — the compact, self-contained design is ideal for mobile shiploaders, telescopic stackers, and portable conveyors where weight, space, and rapid deployment are critical.
Types of Motorized Pulleys
- Built-out Gear-Reducing Motorized Pulley – external gear reducer configuration for easy maintenance access and high torque applications in heavy-duty mining and quarry conveyors.
- Oil-steeped Motorized Pulley – internal components immersed in oil for superior cooling and continuous lubrication, ideal for 24/7 continuous-duty operations in cement plants and power stations.
- Oil-cooled Motorized Pulley – advanced oil circulation cooling for high-power, high-speed applications where thermal stability is critical for reliable performance.
- Explosion-proof Oil-cooled Motorized Pulley – certified for gassy underground coal mines and chemical processing plants requiring ATEX/IECEx compliance for methane and combustible dust atmospheres.
How to Select the Right Motorized Pulley?
Choosing the correct motorized pulley requires matching drive power, belt speed, drum diameter, and belt width to your specific application. ZOOMRY offers driving power from 1.5kW to 630kW with belt speeds from 0.35 to 4.0 m/s. The drum diameter (200mm to 1800mm) determines the belt wrap tension capacity, while the belt width (400mm to 2600mm) must match your existing Conveyor Belt specification. Our engineering team provides full technical support to ensure the correct match for your conveyor's load, speed, and environmental conditions.
