Choosing The Right Gearbox For The Job

There’s a lot to consider when choosing the right DESCH product for your specific application.

Operating Conditions

The operating conditions of the centrifuge or decanter influence the gearbox design, lubrication requirements and overall performance.

Key factors to assess include:

  • Operating speed
  • Torque requirements
  • Continuous-duty requirements
  • Material characteristics
  • Environmental and process conditions

Process Requirements

Different separation processes require different approaches to power transmission and speed control.

When evaluating the application, consider:

  • Centrifuge or decanter configuration
  • Required torque
  • Required operating speed
  • Material consistency and variability
  • Need for variable speed control

Gearbox Technology

DESCH provides three centrifugal gearbox technologies to address different performance and integration requirements.

Our options include:

  • ZG: Planetary gearbox technology for high-speed, high-torque applications
  • ZGD: Differential gearbox technology for variable speed control in decanters
  • ZGC: Compact cycloidal gearbox technology for high power transmission and demanding applications

Maintain For Longevity

While DESCH products are engineered for long-term performance, appropriate maintenance helps protect reliability, extend service life, and prevent avoidable downtime.

  • Follow the recommended installation and commissioning procedures
  • Maintain the correct lubrication level and lubricant condition
  • Monitor gearbox temperature, vibration and operating performance
  • Inspect the gearbox and associated drive components at recommended intervals
  • Address abnormal noise, vibration, temperature or other changes in operation promptly
