NMRV130 वर्म गियरबॉक्स – एल्युमिनियम वर्म गियर रिड्यूसर

⚙ 2,500 Nm Peak — Class-Leading Torque

The highest output torque in the compact NMRV series. For Australian port and mining operations, this weight reduction versus comparable cast iron translates to lower structural steel cost and simpler installation logistics in remote and elevated locations.

📈 12,076 N Radial Load — Highest in Series

Supports the largest industrial chain sprockets (up to 1.5-inch pitch) and heavy V-belt sheaves in overland bulk conveyor drives — eliminating intermediate pillow-block bearing supports and reducing drivetrain component count.

🔥 Centrifugally Cast Bronze Wheel

Denser, more homogeneous alloy structure than sand-cast wheels — delivering higher fatigue strength and longer service life under sustained high-torque, low-speed conditions of major conveyor and agitator drives in continuous 24-hour operation.

⚙ NEMA 210TC — 9.2 kW Motor Ready

Enables direct mounting of 7.5–9.2 kW motors in the 210 frame — the largest class commonly used in compact worm reducer applications in Australian heavy industry — without custom adaptor fabrication costs.

🌞 48 kg vs 100+ kg Cast Iron

At 48 kg, a 50–60% weight reduction versus cast iron reducers of equivalent torque. A replacement unit can be transported in a standard ute tray and installed with portable lifting — versus the heavy crane required for a cast iron equivalent at a remote Australian mine or farm site.

Overland Bulk Conveyors

Head and tail drives for overland iron ore, coal, and bauxite belt conveyors in WA and Queensland — 2,500 Nm handles maximum-load starting torque peaks on the longest loaded belts in Australian bulk commodity export terminals.

⚗

Major Process Vessels

Large-diameter mixing and reactor vessel agitators in chemical, fertiliser, and polymer plants — centrifugally cast bronze wheel withstands cyclic loading of high-viscosity product blending at full torque.

🏛

Major Water Infrastructure

Large clarifier rakes, gravity thickener drives, and penstock gate operators in major Australian water and irrigation authority plants — self-locking at high ratios eliminates brake requirements on power loss.

🏭

Heavy Grain & Food Industry

Large grain terminal elevator boot drives, silo chain conveyor drives, and commercial flour mill main drives — handles high inertia starting loads of heavily loaded grain handling systems in continuous 24-hour service.

★★★★★

“Installed EP-NMRV130 on overland belt conveyor drives at our iron ore terminal in Port Hedland. At 48 kg versus 120 kg cast iron, installation time dropped from two days to six hours per unit. Fifteen months continuous, zero failures.”

Grant Mackenzie 🇦🇺 — Operations Manager, Iron Ore Terminal, Australia

★★★★★

“Specified NMRV130 on large reactor vessel agitators in our chemical plant in Frankfurt. The centrifugally cast bronze wheel held up perfectly under 24-hour continuous high-viscosity blending for over a year. Performance exceeds our specification.”

Hans-Peter Vogel 🇩🇪 — Chief Engineer, Chemical Plant GmbH, Germany

★★★★½

“Using NMRV130 for large clarifier rake drives at our water treatment facility in Buenos Aires. Self-locking at 80:1 holds rake position on power loss. The 12,076 N radial load rating gave us confidence to mount chain drive directly without a separate pillow block.”

Carlos Rodríguez 🇦🇷 — Project Manager, Water Treatment, Argentina

🔌

IEC B5/B14 Motor Adaptors

IEC 132–160 frame adaptors for 5.5–9.2 kW three-phase motors including IE3 high-efficiency and brake motor variants for major industrial drives.

🔃

FA Output Flange (180 mm Pilot)

180 mm pilot diameter, 22.5 deg bolt pattern reference (unique to NMRV130). Direct coupling to large conveyor pulley flanges, clarifier rake arms, and major pump mounting plates.

🔨

Torque Arm (NRV130)

Heavy-duty torque arm rated for sustained 2,500 Nm reaction in shaft-mount conveyor drum and industrial drive configurations.

⚙

External Oil Cooling Coil

Recommended for 24-hour heavy-duty operation in ambient above 30 deg C — maintains oil below 90 deg C in tropical Australian and high-ambient process environments.
