EP-SSRV050 Stainless Steel Worm Reducer

Standard cast iron worm reducers corrode in food plant washdown environments within months. The EP-SSRV050 eliminates this failure mode with a precision-cast 316L stainless steel housing, electropolished to Ra ≤ 1.6 µm, and filled with NSF H1 registered food-grade synthetic oil as standard. Every unit arrives ready for HACCP-compliant food plant installation — no material change, no oil swap required.

The RV-style compact housing accepts IEC motor flanges directly via PAM adaptor for motor frames 63/71/80 IEC. Eleven speed ratios from 7.5:1 to 100:1 in the same external dimensions simplify inventory management for multi-speed production line designs.

■ 316L SS Housing — Corrosion Proof in Acids, Alkalis, and Chlorides

The EP-SSRV050 housing is precision-cast 316L stainless steel — not coated cast iron. Withstands 2–3% NaOH CIP cleaning, 1% phosphoric acid, and 200 ppm chlorinated sanitiser wash cycles without pitting or galvanic corrosion.

■ NSF H1 Food-Grade Synthetic Oil — Standard, Not Optional

Every unit ships with NSF H1 registered fully synthetic ISO VG 150 lubricant. No food-grade oil upgrade required — HACCP compliance begins at first installation without an oil change.

■ Ø25 mm Output Shaft — 63/71/80 IEC Motor Frames

Precision-ground Ø25 mm output shaft in 316L stainless steel. Compatible with IEC motor frames 63/71/80 IEC via PAM B5/B14 flange adaptors. Output options: A (single shaft), B (double shaft), E (torque arm), F (flange).

■ 11 Ratios 7.5–100:1 — Same External Envelope

All eleven speed ratios fit within identical external housing dimensions. Ratio changes do not require new mounting hardware, a key advantage when tuning production line speeds without machine redesign.

■ Electropolished Surface Ra ≤ 1.6 µm — Hygienic and Cleanable

Electropolished 316L external surfaces minimise microbial retention and cleaning chemical consumption. Optional Ra ≤ 0.8 µm electropolish available for pharmaceutical and ultra-hygienic applications.

■ EHEDG Compatible — EU Hygienic Equipment Standard

No external fastener threads exposed in product contact zones. Smooth external geometry with no recesses. Compatible with EHEDG guidelines for hygienic mechanical drive equipment in food and beverage plants.

⚔ Food & Beverage Production Lines

The EP-SSRV050 survives the daily CIP cycles and wet washdown environments of food processing lines where standard cast iron reducers fail within months. 316L housing, NSF H1 oil, and EHEDG-compatible design satisfy food safety audit requirements across meat, dairy, beverage, and bakery applications.

☵ Pharmaceutical Packaging Drives

Pharmaceutical packaging line drives require materials documentation for HACCP qualification. The SSRV 316L stainless steel housing and FDA 21 CFR 177 material compliance provide the documentation trail auditors require without custom fabrication.

⚒ Chemical Process Equipment

In chemical handling and water treatment environments where chlorides, acids, and alkalis are present, 316L SS housing resists the corrosion that attacks cast iron and aluminium reducers — extending service life from months to years.

⚛ Marine & Offshore Equipment

316L stainless steel’s superior chloride resistance makes the SSRV the correct choice for marine deck equipment, desalination plant drives, and offshore processing machinery where salt spray and humidity accelerate corrosion of ferrous alternatives.

■ Aço inoxidável 316L / 304 — Certificados de material fornecidos

Cada redutor de rosca sem-fim EP em aço inoxidável é fornecido com certificados de teste de material para a liga da carcaça (316L ou 304, conforme especificado). Resistência à tração, alongamento e resistência à corrosão verificados de acordo com a norma EN 10088.

■ Marcação CE + Conformidade com ISO 9001 + FDA 21 CFR 177

Marcação CE completa para a diretiva de máquinas da UE. Produção certificada ISO 9001:2000. Os materiais da carcaça estão em conformidade com a norma FDA 21 CFR 177.1550 para contato incidental com alimentos — aceito por auditores HACCP.

■ Testes de ruído, vazamento e torque antes do embarque

Todas as unidades passam nos seguintes testes: ruído abaixo de 65 dB(A) com carga nominal (mais silenciosas do que as equivalentes em ferro fundido devido à lubrificação sintética), teste de vazamento sob pressurização de 30 minutos e torque de saída dentro de ±5%.

■ Design compatível com EHEDG

Superfícies externas lisas, sem fixadores externos nas zonas de contato com o produto e seladas para limpeza CIP/SIP. Compatível com as diretrizes do Grupo Europeu de Engenharia e Design de Higiene (EHEDG) para o projeto de equipamentos higiênicos.

“EP-SSRV on our filling machine drives. 316L housing passes our weekly caustic washdown — 18 months, no corrosion, no leaks. NSF H1 oil means no re-lubrication protocol change.”

“Replaced aluminium reducers with SSRV on our dairy line. Audit passed first time — auditor confirmed FDA 21 CFR 177 compliance on the material cert. Production runs 22 hours/day without issues.”

“SSRV drives our conveyor in a pH 2 citric acid environment. After 12 months the housing shows zero pitting. Previous cast iron units lasted 4 months.”

“Good performance on our pharmaceutical packaging line. Synthetic oil runs clean, 316L surface is smooth for swab testing. Would appreciate lower-ratio options below 7.5:1.”
