EP-SSRV040 Stainless Steel Worm Reducer

Standard cast iron worm reducers corrode in food plant washdown environments within months. The EP-SSRV040 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 56/63/71 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-SSRV040 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.

■ Ø18 mm Output Shaft — 56/63/71 IEC Motor Frames

Precision-ground Ø18 mm output shaft in 316L stainless steel. Compatible with IEC motor frames 56/63/71 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-SSRV040 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.

■ 316L / 304 Stainless Steel — Material Certificates Supplied

Every EP stainless steel worm reducer ships with material test certificates for the housing alloy (316L or 304 as specified). Tensile strength, elongation, and corrosion resistance verified per EN 10088.

■ CE Marking + ISO 9001 + FDA 21 CFR 177 Compliance

Full CE marking for EU machinery directive. ISO 9001:2000 certified production. Housing materials comply with FDA 21 CFR 177.1550 for incidental food contact — accepted by HACCP auditors.

■ Pre-Shipment Noise, Leak & Torque Testing

Every unit passes: noise below 65 dB(A) at rated load (quieter than cast iron equivalents due to synthetic lubrication), 30-minute pressurisation leak test, and output torque within ±5%.

■ EHEDG Compatible Design

Smooth external surfaces, no external fasteners in product contact zones, and sealed for CIP/SIP cleaning. Compatible with European Hygienic Engineering & Design Group (EHEDG) guidelines for hygienic equipment design.

“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.”
