The Armstrong Design Envelope pump vs. variable speed drive mounted on a wall - white paper

The Armstrong Design Envelope IVS pump is a unique solution available with integrated controls up to 350HP / 250kW.  Configuring a pumping solution to use integrated controls has many advantages over a traditional pump controlled by a variable frequency drive mounted on a wall.  These advantages include: 
  1. Selections save energy and cost.
  2. Impeller trim saves energy and cost.
  3. Superior Control.
  4. Smaller size motor and control.
  5. Wiring VFD mounting bracket savings.
  6. Harmonic distortion
  7. Emission and immunity requirements.
  8. Reflected wave voltage.
  9. Envelope selection reduces risk and cost.
  10. Energy metering Capability.
  11. Saves wall space.
