EPNMRV030 Aluminium Worm Gearbox — Overview
The EPNMRV030 delivers expanded torque capacity within a still-compact 30-series aluminium housing, making it the preferred choice for packaging machinery designers and OEM conveyor builders serving the food and consumer goods industries. Weighing just 1.2 kg and accepting input powers up to 0.18 kW, this model bridges the gap between the entry-level EPNMRV025 and the mid-range EPNMRV040. It offers twelve gear ratios from 5:1 to 100:1 — the widest single-stage span in the compact EPNMRV range — allowing OEMs to standardise on one frame across multiple machine variants and reduce spare-parts inventory. Direct IEC B14 flange mounting eliminates adapter plates and shortens drive-train length.

Key Features & Benefits — EPNMRV030
100:1 Single-Stage — No Compound Box
The EPNMRV030 is the only 30-frame single-stage unit reaching 100:1, delivering 14 rpm from a 1,400 rpm motor without a compound gearbox. This simplifies machine design for label applicators, indexing tables, and low-speed turntables.
Direct IEC B14 Flange Integration
The integral VS motor flange eliminates adaptor brackets and associated misalignment risk. Standard IEC 56-frame motors bolt directly, saving assembly time and the premature bearing failures caused by multi-piece adaptor stacks.
Anti-Leak Multi-Lip Output Seal
Triple-lip output shaft seals and a moulded-in O-ring housing joint prevent oil weeping under vibration — critical for food and pharmaceutical packaging lines where lubricant contamination of product triggers a full line shutdown.
️
Finned Housing Sustains 16-Hour Shifts
The finned ADC12 alloy housing dissipates heat faster than an equivalent cast-iron unit. In packaging machines running multi-shift production, this prevents thermal creep in gear clearances and keeps oil viscosity within design specification.
12 Ratios — One Stocked Part Number
Twelve ratios from 5:1 to 100:1 allow OEMs to use a single frame size across an entire product family, dramatically cutting spare-parts inventory cost and reducing the risk of specifying the wrong model under time pressure.
Application Scenarios — Where the EPNMRV030 Excels
Packaging Machinery & Labellers
The EPNMRV030’s 100:1 ratio and 1.2 kg mass make it standard for label-applicator head indexing, shrink-tunnel conveyor drives, and blister-pack feed rollers across Australian and New Zealand FMCG packaging plants. Multiple flange options reduce integration time. Keyword: worm gear reducer for packaging machinery Australia
Beverage Bottling Line Drives
Sealed housing and food-grade synthetic oil fill suit bottling carousel drives, fill-head rotators, and cooling-tunnel conveyors in wine, beer, and carbonated-drinks plants. Smooth low-speed output minimises bottle tip-over and product spillage at fill stations. Keyword: food-grade worm gearbox for beverage bottling lines
Modular Conveyor Drives
Short-pitch conveyor modules in electronics assembly, logistics sortation, and cold-chain distribution use the EPNMRV030 as a plug-in unit. Its bolt pattern aligns with standard 80 mm aluminium extrusion profiles for tool-free lane reconfiguration. Keyword: compact worm reducer for modular conveyor belt drives
Pharmaceutical & Lab Automation
Blister-seal indexing units and dispensing carousel drives in pharmaceutical clean rooms choose the EPNMRV030 for its sealed housing that passes routine washdown cycles. Smooth output minimises vibration at precision fill nozzles. Keyword: sealed worm gearbox for pharmaceutical automation
Selection Guide & Comparison — EPNMRV030
How to Select the Right EPNMRV Model
Select the EPNMRV030 when output torque is 10–25 Nm and input power is 0.06–0.18 kW. Ratios 25:1–100:1 suit packaging indexing at 14–56 rpm. Ratios 5:1–20:1 suit faster conveyors at 70–280 rpm. Step up to EPNMRV040 if torque exceeds 25 Nm.

EPNMRV030 vs Traditional Cast-Iron Worm Reducer
| Attribute | EPNMRV030 (Aluminium) | Traditional Cast-Iron | Advantage |
|---|---|---|---|
| Weight | 1.2 kg | ~3.5 kg typical | 66% lighter — easier single-person fitting |
| Single-stage max ratio | 100:1 | 60:1 typical | No compound box for 14 rpm output |
| Oil leak risk | Multi-lip seal + O-ring joint | Single lip standard | Better for food-line contamination control |
| Thermal management | Finned alloy — fast cooling | Solid cast iron | Sustains 16-hour production shifts |
| Mounting | Foot + IEC B14 flange | Foot only standard | More machine layout flexibility |
Frequently Asked Questions — EPNMRV030
What makes the EPNMRV030 different from the EPNMRV025?
The EPNMRV030 provides a larger 16 mm (0.625 in) output shaft, 25 Nm maximum torque versus 15 Nm, and extends the ratio range to 100:1 with twelve options versus nine in the 025. Input power capacity doubles from 0.09 kW to 0.18 kW. Choose the 030 for packaging machinery requiring ratios of 60:1, 80:1, or 100:1 in a single-stage unit.
Is the EPNMRV030 available with a NEMA input flange?
Yes. The inch series accepts a NEMA 48C flange (0.5 in bore), compatible with standard North American 1/20–1/4 HP motors. This makes the unit suitable for machine exports to the US, Canada, and Mexico without separate adaptor plates.
What output flange options are available?
The EPNMRV030 offers an FA output flange (PCD 54.9 mm, 4 × M6) in addition to solid shaft and hollow bore variants. The FA flange allows direct mounting of conveyor sprockets and indexing discs, reducing radial load on the output shaft bearing versus a cantilevered coupling.
How do I calculate the gear ratio needed for my conveyor?
Divide required belt speed (m/min) by the sprocket pitch-circle circumference (diameter × π) to get the required output rpm. Then divide motor speed (typically 1,400 rpm at 50 Hz) by required output rpm and round to the nearest standard ratio. Example: 28 rpm output needs 1,400 ÷ 28 = 50:1.
Can the EPNMRV030 run in cold-chain refrigerated environments?
Yes, with ISO VG 100 synthetic gear oil replacing the standard VG 220 for operation below 0 °C. The ADC12 aluminium housing retains dimensional stability to −30 °C. Specify low-temperature-rated seal lips if ambient drops below −15 °C continuously.
What is the standard oil fill volume?
Approximately 0.11 litres of ISO VG 220 gear oil in horizontal B3 mounting. Vertical V5/V6 orientations require 0.14–0.16 litres. The sealed housing is maintenance-free under standard duty; inspect oil at 10,000-hour intervals.
Is the EPNMRV030 suitable for continuous 24/7 packaging plant operation?
Yes, provided operating torque and power stay within rated limits. For continuous duty at maximum 0.18 kW, ensure at least 50 mm of clear airspace around the housing for natural convection cooling. In enclosed cabinets add a small fan directed at the housing fins.
