WASHDOWN HYGIENIC The VFD Series

Product catalog summary

Overview: The document provides technical specifications and features of the VFD Series aluminum worm gearboxes, focusing on their hygienic design, protective coatings, and corrosion resistance.

Specifications: The gearboxes are available in various models with different torque, center distance, input power, and output shaft dimensions. Key models include D30, D50, D85, D45, and D63, with torque ranging from 21 Nm to 347 Nm and input power from 0.06 kW to 4.0 kW.

Design and Protection: The gearboxes feature a smooth surface design for easy cleaning and are available with a white protective paint for medium aggressive environments. The painted version offers enhanced corrosion resistance, as demonstrated by a salt spray test where the painted gearbox showed no signs of corrosion after 1200 hours.

Corrosion Resistance: The document includes a graph comparing the corrosion resistance of unpainted and painted gearboxes. The unpainted gearbox showed signs of corrosion after 100 hours, while the painted version remained unaffected after 1200 hours.

Materials and Construction: The gearboxes are constructed with a single-piece aluminum alloy housing, vacuum impregnated to MIL-STD 276 standards. They feature hardened and ground worms with radiused teeth for noise reduction. Options include stainless steel or zinc-plated components for enhanced durability.

Sealing Options: Various sealing options are available, including NBR seals for standard applications and Viton seals with stainless steel shields for IP69k protection in harsh environments.

Recommendations: For environments with aggressive chemical agents, the use of full stainless steel gearboxes (N series) is recommended. Specific tests in the working environment are suggested to ensure compliance with minimum requirements.
