Vertical In-Line - Retrofit to Design Envelope

Brand: Armstrong Fluid Technology

A retrofit of an existing constant speed Armstrong Vertical In-line to a Armstrong Design Envelope Vertical In-line pump utilizing the existing casing and replacing all other components.

Pipe-mounted with integrated intelligent controls for continued space savings and superior energy performance.  Saves up to 70% in energy compared to traditional constant speed pump installations.
Features
  • The retrofit does not require pipe changes or even disconnecting the casing so no fewer hours are required for the work and no pressure test is required
  • There are savings in the product cost as there is no casing
  • The insulation does not need to be removed and replaced
  • Relative to the installation of a separate third party drive, there is no additional wiring because wiring is already available to the motor
  • Superior energy performance qualifies for utility or government rebate programs in many jurisdictions
  • Integrated intelligent controls – combined with perfect component match-up and tuning – for up to 70% in energy savings when compared with the existing constant speed – constant flow application
  • Split-coupling design for easy seal change service without removal of the pump or motor
  • Up to 70% reduction in energy cost and associated greenhouse gas emissions
  • Keep existing casing out of landfill or recycling
  • Keep existing insulation on casing
  • Reduce shipping weight of heavy casing from foundry to assembly plant to customer
  • Integrated intelligent controls for fast and easy commissioning as well as reduced radio frequency interference/improved electromagnetic compatibility
  • Independent operation through embedded Sensorless control or in conjunction with a building automation system (BAS)
