EP-SSVF50 Stainless Steel Worm Reducer

Vessel-mounted and column-mounted drives in food, pharmaceutical, and chemical environments have a specific requirement the foot-mount SSRV cannot meet: direct flange-face mounting to a vessel nozzle without a separate base plate or floor frame. The EP-SSVF50 is designed exactly for this. The VF-type housing bolts directly to vessel nozzle flanges, column flanges, or wall-mount brackets via a precision-machined flat face — no base plate, no pedestal, no contamination trap.

316L stainless steel housing, electropolished Ra ≤ 1.6 µm, NSF H1 food-grade synthetic oil as standard, ratios 7.5–100:1, and IEC motor compatibility via PAM B5/B14 adaptors for frames 63/71/80 IEC. One product — the complete specification for hygienic flange-face vessel drive applications.

■ VF Face-Mount — Direct Vessel Nozzle Bolt-On

The EP-SSVF50 VF-type flat face bolts directly to vessel nozzles, column flanges, and wall-mount brackets. No separate base plate, no contamination-trapping floor frame — the cleanest possible drive installation for hygienic vessel applications.

■ 316L Stainless Steel — All Wetted Surfaces

Housing, output shaft, and all external surfaces are 316L stainless steel. No ferrous components in potential product contact zones. Material certificates supplied with every unit.

■ NSF H1 Food-Grade Synthetic Oil — Pre-Installed

Ships with NSF H1 registered ISO VG 150 synthetic oil. No oil change required at commissioning. First service interval 5,000 hours under normal food plant operating conditions.

■ IEC Motor Frames 63/71/80 IEC — PAM B5 & B14 Adaptors

Compatible with 63/71/80 IEC IEC motor frames via standard PAM B5 and B14 flange adaptors. Motor couples directly to the VF housing without custom adaptors or coupling brackets.

■ 11 Ratios — Same Mounting Envelope

Ratios 7.5 to 100:1 all fit within the same external VF housing dimensions — enabling ratio changes without modifying the vessel nozzle or mounting hardware.

■ Electropolished Ra ≤ 1.6 µm — EHEDG Compatible

Smooth electropolished external surfaces minimise bacterial adhesion and cleaning chemical consumption. Compatible with EHEDG hygienic design guidelines.

⚔ Food Processing Vessel Face-Mount Drives

The EP-SSVF50 VF face-mount eliminates the floor frame from food plant vessel drive installations — reducing contamination risk, simplifying cleaning validation, and meeting EHEDG hygienic design requirements for vessel-mounted equipment.

☵ Pharmaceutical Vessel & Bioreactor Drives

Pharmaceutical bioreactor and mixing vessel drives require IQ/OQ/PQ documentation for every drive component. The SSVF provides 316L material certs, NSF H1 oil cert, and FDA 21 CFR 177 compliance documentation to support validation packages.

⚒ Chemical Process Vessel Column Drives

Flange-mount to column and vessel nozzles in chemical plant without a floor frame — compact installation in tight vessel spacing. 316L SS resists the acid and alkali environments that destroy cast iron and aluminium within months.

⚛ Beverage Tank Agitator Drives

Beverage plant tank agitator drives using VF face-mount reduce the equipment footprint within tight tank farm layouts — direct flange-to-nozzle installation eliminates floor frame and base plate from every tank drive position.

■ 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-SSVF on our vessel face-mount drives. VF face-mount bolts directly to the vessel nozzle flange — no bracket needed. 316L housing, food-grade oil, passed our BRC audit without exception.”

“Used SSVF on our face-mount mixer drives. The VF flange bolts straight onto our reactor vessel flanges. Electropolished surface passes our swab testing. Excellent design for hygienic vessel drives.”

“SSVF on our pharmaceutical filling machine face-mount drives. FDA 21 CFR 177 material certs provided with the unit. NSF H1 oil already installed. No additional qualification steps needed.”

“Good VF face-mount stainless reducer for vessel applications. SSVF50 running clean for 14 months on our food line. Would appreciate an IP65 option for full submersion CIP.”
