Overview

VERTICAL INLINE WITH CUE DRIVE

Type VLC (Close Coupled)
Type VLSC (Split Coupled)

 

The Grundfos line of VLC/VLSC, single stage, inline pumps with CUE drive (Grundfos variable frequency drive), and control are part of the family of pumps, which are better engineered to increase efficiency and reduce radial loads. The VLC and VLSC pumps are the smart choice for number of reasons.

  • Pump, motor, and variable frequency drive are supplied by one supplier
  • All components you need are in one pump
  • Simple set up on CUE with predefined control modes
  • 16 steps to get a system up and running
  • Energy savings due to on-demand performance
  • Grundfos sensor technology
  • Vertical inline mounting for floor space savings
  • Axially split coupling enhances ease of service and alignment (VLSC)
  • Spacer coupling allows easy replacement of mechanical seal without removing the motor and drive (VLSC)
  • Highly efficient for reduced operation costs
  • Integrated frequency drive cuts planning, purchasing, installation, and commissioning costs
