EP-NMRV110 Large Industrial Aluminium Worm Reducer – Product Overview

The EP-NMRV110 brings the weight and corrosion advantages of aluminium to large industrial drive applications – 648 Nm output torque from input powers up to 9.2 kW. At 35 kg it remains notably lighter than the 50+ kg cast iron equivalents at this torque level, making overhead, wall-mount, and remote-site installations substantially more practical. The 110 mm centre distance and Ø42 mm output shaft handle heavy conveyor head drives, large mixing vessel agitators, and industrial process machinery. IEC motor frames from 80 to 210 connect directly via B5 or B14 flange. Compatible with PC080 and PC090 helical pre-stages for extended ratio ranges. Also serves as the output stage for NMRV050/110 double-stage combinations reaching 5000:1 with output torques up to 1396 Nm.

✓ Core Features and Benefits

⚒ 648 Nm – Heavy Industrial in Aluminium
The first NMRV size that routinely replaces cast iron in mining, heavy process, and large conveyor applications. Proves that aluminium can deliver heavy-duty torque at serious industrial levels.

⚙ IEC Frames 80 to 210 – Up to 9.2 kW
Accepts large IEC motor frames directly for heavy-duty applications. Frame 200 and 210 support enables applications previously reserved exclusively for cast iron housings.

❄ 35 kg vs 50+ kg Cast Iron Equivalent
30% lighter than cast iron equivalent – practical for installation on elevated conveyors and mezzanine-mounted drives where every kilogram affects structural steel requirements.

⚖ PC080/PC090 Pre-Stage + Double-Stage to 5000:1
PC080 and PC090 helical pre-stages for extended ratios with higher efficiency. NMRV050/110 double-worm reaches 5000:1 with up to 1396 Nm output – the heaviest double-stage combination below NMRV130.

⚙ Industry Applications

⚊ Mining Belt Conveyor Drives
Heavy-duty head drives for medium-capacity ore, coal, and mineral belt conveyors. 648 Nm handles loaded belt starts and continuous running torque. 35 kg enables underground installation by two workers.

☵ Large Industrial Agitator Drives
Industrial mixing drives for chemical reactors, water treatment clarifiers, and mineral processing vessels. Ø42 output matches heavy agitator shaft coupling bore sizes directly.

⚙ Heavy Process Machinery
Palletiser main drives, heavy indexing tables, and production line main conveyors exceeding 400 Nm torque requirements. FA and FB flanges for direct machine frame mounting.

☀ Renewable Energy Systems
Large solar tracker drives and wind turbine yaw mechanisms. PC090 helical pre-stage extends the ratio to 196:1 for slow tracking speed applications.

⚙ Selection Guide and Mounting Positions

Select the NMRV110 for output torque requirements between 264 Nm and 648 Nm at input power up to 9.2 kW. Step up to the NMRV130 at 1596 Nm for the heaviest loads. The NMRV090 at 479 Nm covers moderate-heavy applications at lower weight.

⚖ Aluminium vs Cast Iron at Large Frame Sizes

At the 110 mm frame size, the weight difference between aluminium and cast iron becomes a significant factor in structural design. Replacing a 50+ kg cast iron unit with a 35 kg aluminium NMRV110 can allow lighter support steel – reducing total installed cost.

Feature	Aluminium NMRV	Cast Iron
Weight	30-50% lighter	Heavier
Corrosion	Excellent	Poor
Heat Dissipation	Superior	Moderate
Cost	Lower	Higher
Noise	Low	Moderate
IEC Motor	Direct B5/B14	Adaptor often needed

❓ Frequently Asked Questions

▶ What is the maximum output torque of the EP-NMRV110?

648 Nm at 30:1 ratio with approximately 2.2 kW input. In NMRV050/110 double-stage: up to 1396 Nm at 5000:1 ratio.

▶ Can the NMRV110 replace cast iron reducers at this size?

Yes for most applications. At 35 kg versus 50+ kg, the aluminium NMRV110 provides equivalent torque capacity at significantly lower weight. Exception: extreme shock loading applications such as mining crushers may still require cast iron.

▶ What is the PC090 helical pre-stage?

PC090 is a helical gear pre-stage providing ratios from 73.6:1 to 196.4:1 with higher transmission efficiency than double-worm at comparable ratios. Standard for large solar and positioning drives.

▶ What is the NMRV050/110 double-stage configuration?

NMRV050 as pre-stage plus NMRV110 as output stage reaches ratios from 3000:1 to 5000:1 with output torques up to 1396 Nm. Standard for extreme-ratio heavy-duty applications.

▶ Thermal capacity at 9.2 kW?

At maximum input power, verify thermal service factor above 1.0. For continuous duty above 7 kW in ambient over 30°C, supplementary fan cooling or duty cycling is recommended.

★ Customer Reviews

★★★★★

“NMRV110 on our coal conveyor heads. 35 kg – two workers install on the mezzanine without a crane. 648 Nm handles loaded belt starts reliably. 22 months running, zero unplanned downtime.”

Bruce H. – Hunter Valley Mining (Australia)

★★★★★

“Replaced cast iron on 6 agitator drives. NMRV110 saved us 90 kg total across the vessel platform – our structural engineer approved a lighter frame design as a result.”

Lisa M. – ProcessTech Inc. (United States)

★★★★★

“PC090 plus NMRV110 on our solar farm main tracking drives. 196:1 ratio with efficient helical pre-stage. Better overall performance than the double-worm setup we previously used.”
