What Makes the EPSS Series Different
The following specifications apply across all four EPSS models. Individual model pages do not repeat this information.
304 Stainless Steel Housing
Complete housing, flanges, and feet in AISI 304 stainless steel with electro-polished finish. No paint, no coating — nothing to flake, chip, or contaminate. Inherently resistant to sodium hydroxide, peracetic acid, and chlorinated cleaning agents used in food-industry CIP/COP procedures. Smooth surface profile minimises bacterial harbourage points.
IP69K Washdown Rating
The highest ingress protection rating in industrial use. Withstands 80-100 bar water jets at 80 degrees C from 100-150 mm distance at all angles — the exact conditions used in meat, dairy, and pharmaceutical washdown protocols. No protective covers, bags, or shrouds required during cleaning. Exceeds EN 60529 and DIN 40050 Part 9 requirements.
VITON (FKM) Seals as Standard
Every EPSS unit ships with VITON fluoroelastomer seals — not the NBR seals used as standard on general-purpose gearboxes. VITON resists the full chemical spectrum of food-industry cleaning: NaOH, peracetic acid, quaternary ammonium compounds, chlorine, and hot water. Continuous temperature range: -20 degrees C to +200 degrees C.
20CrMnTi Worm Shaft — Zi Profile
Carburised alloy steel worm shaft with Zi involute globoid tooth profile. The Zi geometry provides a larger contact area than standard ZA/ZN profiles, distributing load across more tooth surface and reducing contact stress. Result: higher load capacity, lower noise, and longer wear life under the same operating conditions.
CuSn12Ni2 Nickel-Tin-Bronze Wheel
A higher-grade bronze alloy than the CuSn10Pb1 used in standard worm gearboxes. The 12% tin and 2% nickel content increases tensile strength from approximately 250 MPa to 310 MPa, while the nickel addition improves corrosion resistance — relevant in food environments where trace lubricant may contact product.
NSF H1 Food-Grade Lubricant
Factory-filled with fully synthetic NSF H1 registered lubricant, compliant with FDA 21 CFR 178.3570 for incidental food contact. Eliminates the risk of non-food-safe lubricant contamination. Additional O-ring on the input flange face provides a secondary moisture barrier at the motor-gearbox interface during washdown.
Food Industry Certifications & Compatibility
HACCP Compatible
304SS construction with no paint contamination risk supports HACCP plan compliance in high-care food zones.
FDA 21 CFR 178
NSF H1 lubricant compliant with FDA regulations for incidental food contact applications.
IP69K / EN 60529
Withstands high-pressure, high-temperature washdown per EN 60529 and DIN 40050 Part 9.
