Description

The 812745 Gear Reducer SK72-W 10.84:1 1750/161 RPM is a precision mechanical component designed for reliable power transmission in pump systems.

Constructed primarily from high-strength metal alloys, the 812745 Gear Reducer features a durable gear set made of hardened steel to ensure longevity and wear resistance. Its casing is typically composed of cast iron or reinforced aluminum, offering corrosion resistance and structural stability for demanding industrial environments.

The reducer measures approximately 12 inches in length, 8 inches in width, and 10 inches in height, with a weight nearing 25 kilograms (55 pounds). It supports input shaft diameters up to 1.25 inches, compatible with standard motor shafts. The output shaft is designed for a 1-inch keyway, optimized for coupling to pumps. It accommodates shaft alignment and flange mounting based on industry standards, facilitating integration into existing systems.

  • Gear ratio: 10.84:1, converting 1750 RPM input to approximately 161 RPM output
  • Input speed range: up to 1750 RPM with a maximum torque capacity of 300 Nm
  • Efficiency: exceeding 95% under optimal conditions
  • Lubrication: requires API GL-5 gear oil, with a recommended oil capacity of 1.5 liters
  • Operation temperature: -20°C to +80°C, ensuring performance in diverse environments
  • Corrosion resistance features: sealed housing and high-grade corrosion-resistant gears

This gear reducer is ideal for use in pump applications such as positive displacement and sliding vane pumps, where precise speed reduction and torque stability are critical. It is well-suited for industries including water treatment, chemical processing, and manufacturing, where consistent pump performance and durable drive components are required. Its 812745 Gear Reducer is recommended for budget-conscious operations seeking a reliable, heavy-duty gear reduction solution.

Included in the box are the gear reducer assembly, mounting hardware, and installation instructions. Not included are the coupling and motor, which must be purchased separately to match the existing system specifications.

For maintenance, ensure regular lubrication checks and replace gear oil according to manufacturer guidelines. The gear reducer features a sealed housing that requires minimal servicing, and a standard warranty covers parts against manufacturing defects for up to 12 months from purchase. Cleaning involves wiping with a damp cloth; avoid harsh chemicals that may damage the housing or gears.
