Built for Durability

AKMA motors are engineered for performance and longevity in tough washdown environments and uncertain outdoor conditions.

Unsurpassed durability starts with the motors’ hardened anodized aluminum coating that provides strong chemical resistance in a wide pH range to withstand common cleaning agents in washdown. You’ll find:

  • Coating that is less vulnerable to scrapes, dents, and paint flaking than conventional epoxy
  • Stainless-steel shaft with chromium oxide inlay maximizes lifetime of the shaft seal
  • Vented design and “one-piece” housing structure eliminates the O-ring to reduce risk of water ingress

  • Smooth surface ensures simple cleanability in environments where cleanliness is essential
  • Round housing prevents contamination droplets from pooling
  • IP69K-rated sealing allows higher pressure exposure for food-grade environments
