Descripción

EP-SSVF63 — Stainless Steel VF Worm Gear Reducer Overview

Large-format food and chemical processing machinery — industrial mixers, slow-speed drum drives, and heavy filling-line conveyors — that require a face-mount stainless worm reducer with 90B5/B14 motor compatibility need a product that delivers the power density of a 90-frame motor in the compact axial footprint of the VF hollow-flange architecture. The EP-SSVF63 Stainless Steel VF Worm Gear Reducer provides this: 304 precision-cast electropolished housing, Ø25 mm 304 stainless output shaft, six PAM-IEC flange options spanning 71–90 IEC frames (0.18–0.75 kW), and the SSVF series’ largest housing at 166 mm total length and a Ø95 mm input-flange face. As the top model in the SSVF family, the SSVF63 handles the most demanding hygienic face-mount drive applications and offers the SSVF series’ widest torque output, making it the go-to selection for seafood-processing conveyors, pharmaceutical drum-coating drives, and large vessel agitators.

Core Features & Benefits

90-Frame Motor Flange — Maximum Power in SSVF Range (0.75 kW)

The SSVF63’s 90B5/B14 PAM-IEC adapter unlocks up to 0.75 kW continuous input — the highest in the SSVF series — enabling it to serve heavy agitators and drum drives that SSVF40/50 cannot reach in terms of motor power.

Ø95 mm Input Face — Largest SSVF Housing, Highest Torque Density

The Ø95 mm input flange face and 166 mm total length of the SSVF63 provide the largest worm gear pair in the SSVF family, delivering the highest output torque per unit housing volume in the range — maximising torque density in face-mount stainless applications.

Output Flange KM=150 mm PCD — Standard VF63 Mating Geometry

The SSVF63..F output flange (KA=82 mm, KM=150 mm, KP=180 mm, 11 bolt positions) matches the standard VF63 output-flange geometry across the industry, ensuring drop-in compatibility when upgrading from aluminium VF63 to stainless.

150 mm Torque Arm (304 SS) — Increased Reaction-Torque Capacity

The SSVF63’s 304 SS torque arm (K1=150 mm, G=14 mm, B=6 mm) provides greater reaction-torque capacity than the 100 mm arm of smaller models, supporting the higher output torques of 0.55–0.75 kW applications in shaft-mount configurations.

Electropolished 304 Housing — EHEDG-Compatible Surface Quality

All six external faces of the SSVF63 housing are electrolytically polished to Ra ≤ 0.8 µm, meeting the EHEDG (European Hygienic Engineering & Design Group) surface-quality guideline for equipment used in wet food-processing environments.

Industry Applications & Typical Use Cases

🐑

Seafood & Fish Processing Conveyors

Salt-water, blood-acid, and enzyme environments in seafood processing destroy aluminium drives quickly. The SSVF63’s 304 housing and stainless output shaft maintain integrity through high-frequency CIP and high-pressure washdown in these aggressive conditions.

📑

Pharmaceutical Drum Coating & Pan Drives

Tablet-coating pan drives in pharmaceutical manufacturing require slow, quiet, smooth rotation (2–15 rpm), hygienic surfaces, and face-mount integration into the pan frame. The SSVF63’s VF flange and silent worm mesh fulfil all three requirements.

🍾

Brewery & Winery Process Drives

Mash-turn agitators, grape-crusher conveyor drives, and must-pump drives in brewing and winemaking specify the SSVF63 for its resistance to acetic acid, SO₂, and ethanol environments, combined with the power range to drive large-volume vessels.

📣

Industrial Mixing & Agitation

Heavy-duty paddle agitators and ribbon blenders in batch chemical, pigment, and adhesive mixing specify the SSVF63 for its 0.75 kW input rating, self-locking at ratios ≥ 30:1, and corrosion-safe stainless construction.

Water Treatment Equipment

UV steriliser conveyor drives, chemical-dosing slow-speed mixers, and sludge conveyor drives in water-treatment plants use the SSVF63 for its resistance to chlorinated water and its compact face-mount installation that saves floor space in equipment rooms.

Selection Guide, FAQ & Customer Reviews

How to Select the Right SSVF Model

1. Define required output torque (Nm) and output speed (rpm) from your process requirements. 2. Calculate ratio = motor speed ÷ output speed. 3. Match motor frame to available PAM-IEC adapters for EP-SSVF63. 4. Check VF flange compatibility — confirm your driven-machine flange accepts the SSVF63 output-flange PCD (KP=180 mm, 11 bolt holes). 5. Specify accessories — 304 SS output shaft (DS/SS), torque arm, or ..F flange option as needed.

❓ Frequently Asked Questions

▼ What distinguishes the SSVF63 from the SSVF50 in terms of technical capability?
The SSVF63 adds 90B5 and 90B14 motor-flange compatibility (unavailable on SSVF50), extending maximum continuous input power from 0.37 kW (SSVF50) to 0.75 kW (SSVF63). The housing is larger (166 mm total length vs ~134 mm for SSVF50), the input flange face is Ø95 mm vs Ø85 mm, and the torque arm grows from K1=100 mm to K1=150 mm. Output shaft diameter remains Ø25 mm in both models.
▼ What is the maximum output torque of the EP-SSVF63?
At ratio 100:1 from a 90B5 (0.55 kW) motor, the EP-SSVF63 delivers approximately 250–310 Nm at the output shaft. At ratio 7.5:1, output torque is approximately 25–35 Nm at higher output speed. Use the model selection table for exact torque values at your specific operating point.
▼ How do I specify the SSVF63 for a seafood-processing application with high-pressure washdown?
For high-pressure washdown (IPX6/IP69K), specify: (1) EP-SSVF63, (2) enhanced double-lip Viton shaft seals (on request), (3) sealed vent plug in place of standard breather, (4) H1 food-grade oil fill. All external fasteners should be 316L or A4-70 stainless for maximum corrosion resistance in salt-spray environments.
▼ Can the EP-SSVF63 be used with a DC brushless (BLDC) motor?
Yes. The SSVF63 worm gear drive is motor-agnostic — it accepts any motor with a compatible PAM-IEC input flange. BLDC motors are common in speed-controlled hygienic drive applications. Confirm that the motor flange frame (71–90 IEC) matches one of the six available PAM-IEC adapters for the SSVF63.
▼ What is the typical efficiency of the SSVF63 at ratio 30:1?
Worm gear efficiency at ratio 30:1 is typically 72–80% for a 12-2 tin-bronze wheel with the hardened steel worm shaft specified in the SSVF63. Efficiency decreases as ratio increases: approximately 65–72% at 60:1, and 50–60% at 100:1. The selection table provides input power and efficiency data for all standard ratios.
▼ Does Ever-power offer custom housing materials for more aggressive chemical environments?
Yes. For environments where 304 SS is insufficient (e.g., strong chloride solutions, seawater immersion, highly concentrated acids), Ever-power can supply selected SSVF models with 316L stainless steel housings as a custom option. Contact our applications engineering team with your specific chemical exposure conditions.

“Running 24 SSVF63 units on our prawn and salmon conveyor lines. Salt water, enzyme baths, and twice-daily CIP cycles. After 20 months, every unit is in perfect condition. The 90B5 motor flange was essential for the torque we needed. Best stainless gearbox we have used.”

“Installed on our drum-coating pan drives for pharmaceutical tablets. The VF face-mount to the pan shaft was straightforward — no alignment needed. Smooth, quiet worm mesh at ratio 40:1 meets our GMP noise requirements. Electropolished surface looks excellent after six months of operation.”

Elena Gonzalez — Industrias Alimentarias SL

“SSVF63 on our miso fermentation agitators. The salt and acid environment was our main concern — the 304 stainless housing has handled it well. Good torque at ratio 30:1 for the viscous miso batch. One request: provide a metric technical manual rather than dimension drawings only.”
