WPA Cast Iron Worm Reducer — Product Overview
그만큼 WPA is the benchmark foot-mount worm reducer in the WP series, chosen where engineers need a rugged, standard-dimension drive unit that installs directly into existing conveyor frames, agricultural machinery, and industrial processing equipment. The FC20+ grey cast iron housing delivers inherent vibration damping under sustained loads up to 2,371 Nm, supporting 50,000+ hour service life across continuous-duty applications.
Its defining feature — a bilateral input shaft — accepts motor connection from either side without ordering a mirrored unit, eliminating adaptor brackets and simplifying installation on compact machine frames. 12 standard sizes from 40–250 mm centre distance cover 0.12–33.20 kW input power across the full range of standard motor frames.

WPA Worm Reducer — Core Features
■ FC20+ Cast Iron — 3× Vibration Damping vs Aluminium
Precision-machined FC20+ grey cast iron absorbs shock loads that would fatigue aluminium housings, extending bearing life in conveyor and agricultural applications with high-vibration duty cycles.
■ Bilateral Input Shaft — Motor from Either Side
Both ends of the worm shaft are accessible on every WPA, allowing left- or right-hand motor connection without a mirrored unit. Reduces installation time and eliminates custom bracket fabrication on confined machine frames.
■ 12 Sizes: 17 Nm to 2,371 Nm Output Torque
From compact 40 mm units at 17–26 Nm to heavy-duty 250 mm units at 1,881–2,371 Nm, a single WPA series covers the entire range of standard conveyor, pump, and agricultural drive requirements.
■ Four Mounting Orientations Without Hardware Changes
B3 horizontal, B6 output-up, B7 output-down, and B8 reverse — all supported without modification. Adjust oil quantity per orientation per the lubrication chart.
■ 20CrMnTi Worm Shaft at 55–60 HRC
The carburised, precision-ground worm shaft maintains mesh geometry over 50,000+ hours. Noise level remains below 68 dB(A) at rated load across the full 1/5–1/60 ratio range.
■ Oil Gauge + Drain Plug Standard
Every WPA includes an oil level sight glass and bottom drain plug as standard. First oil change at 100 hours (run-in), then every 2,500 hours — a 15-minute task requiring no specialist tools.
WPA Worm Reducer — Industry Applications
⚊ Grain Auger & Conveyor Drives
The WPA foot-mount base installs directly into standard conveyor frame bolt patterns. Sizes 100–135 at 1/20–1/40 ratios are the standard choice for grain auger drives, where 24/7 harvest-season operation demands cast iron durability over lighter alternatives.
☷ Agricultural Machinery
Powers seed drills, slurry spreaders, and irrigation pump drives. The bilateral input shaft allows motor positioning on either machine side without custom brackets — reducing OEM build time per machine.
⚒ Packaging & Bottling Lines
WPA-60 to WPA-100 deliver precise speed reduction for carton formers, labelling conveyors, and palletiser turntables. Operation below 68 dB(A) meets food factory noise floor requirements.
⚙ Pump & Fan Drives
Continuous 95°C oil temperature rating suits pump station and HVAC fan applications where full-load operation is continuous rather than intermittent.
Ever Power Manufacturing Quality — WPA Worm Reducer
■ ISO 9001:2000 Certified
Every unit is manufactured under ISO 9001:2000 quality management. Raw material inspection, in-process checks, and final testing are all documented and traceable to each unit’s serial number.
■ CE 마크 — EU 기계류 지침 2006/42/EC
CE 인증을 완벽하게 준수하여 기계식 동력 전달 장치에 대한 유럽 안전 및 설계 표준을 충족함을 확인했으며, EU, 영국, 호주 및 뉴질랜드 시장으로의 수출을 지원합니다.
■ 출하 전 테스트: 소음, 누출, 토크
Every unit passes three tests before shipping: noise below 68 dB(A) at rated load, 30-minute pressurisation leak test, and torque transmission within ±5% of rated value. Non-conforming units are reworked — not shipped.
■ FC20+ 소재 인증
Housing castings are verified by mill certificates for FC20 grade: minimum 220 MPa tensile strength, 160–200 HB hardness. Ultrasonic defect testing is performed on size 135 and above.
WPA Worm Reducer — Customer Reviews
“WPA-100 running on our grain auger drives for 18 months — zero failures across 12 units in a dusty, high-vibration environment. The cast iron housing handles impacts that would crack aluminium.”
“Replaced worn units with WPA-80 on our packaging conveyor. Noise dropped from 74 dB to under 68 dB. Bilateral shaft meant no motor rewiring — saved two hours per unit during the changeover.”
“WPA-135 on our irrigation pump at 24/7 for over 14,000 hours with no leaks. The oil gauge boss makes monthly level checks a 30-second task.”
“Good performance on our bottling line. WPA-60 runs quietly in B6 vertical mount on a compact frame. Would appreciate more sizes between 135 and 155 mm.”
