EP-NMRV110 Large Industrial Aluminium Worm Reducer – Product Overview
El 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.

✓ Características y beneficios principales
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.
Accepts large IEC motor frames directly for heavy-duty applications. Frame 200 and 210 support enables applications previously reserved exclusively for cast iron housings.
30% lighter than cast iron equivalent – practical for installation on elevated conveyors and mezzanine-mounted drives where every kilogram affects structural steel requirements.
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.
⚙ Aplicaciones industriales
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.
Industrial mixing drives for chemical reactors, water treatment clarifiers, and mineral processing vessels. Ø42 output matches heavy agitator shaft coupling bore sizes directly.
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.
Large solar tracker drives and wind turbine yaw mechanisms. PC090 helical pre-stage extends the ratio to 196:1 for slow tracking speed applications.
⚙ Guía de selección y posiciones de montaje
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.
| Característica | NMRV de aluminio | Hierro fundido |

| Corrosión | Excelente | Pobre |
| Disipación de calor | Superior | Moderado |
| Costo | Más bajo | Más alto |
| Ruido | Bajo | Moderado |
| Motor IEC | Directo B5/B14 | A menudo se necesita un adaptador |

★ Opiniones de los clientes
“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.”
