Variable Speed Drives

A Variable Speed Drive (VSD) regulates the speed and rotational force, or torque output, of an electrical motor. One of the main reasons why drives save energy is because they can change the speed of an electrical motor by controlling the power that is fed into the machine. They allow protection and control of electric motors, therefore extending the life of motors.

VSD's are a hot topic in the farming sector as this device helps save electricity costs. ESKOM is also pushing this now as more and more farmers are realising the benefits of this equipment. When used on water pumps,VSD's maintain the line pressure in pipes completely constant, independently from fluctuations in outflow and demand. A multi pump VSD can be used with up to 4 water pumps at a time on a single application.

Advantages include:

  • Energy Savings
  • Longer Lifetimes for the pump
  • Maintains the line pressure constant
  • Provides the necessary outflow according to the demand of the system
  • Soft Starts, protecting the mechanical & electrical instillation
  • Alteration in running auxiliary pumps based on operating hours

A VSD can be used on motors such as:

  • Irrigation Pumps
  • Milking Machines
  • Power-plant Fans
  • Sawmill Conveyers
  • Ventilation Systems
  • Sewage Pumps
  • Ski Lifts

We manufacture VSD's with high quality components and materials. Significant savings can be achieved when used on water pumps. We manufacture VSD's in conjunction with water pump motors from 0.75kw to 1000kw.
