GIS has distribution rights for Grundfos CR(N)-H products


GIS is excited to be offering Grundfos’ CR(N)-H, which is an interchangeable ANSI pump solution.  The design of this pump allows it to bolt directly into the piping and pump case footprint of a traditional ANSI pump, with a motor riser block.  The advantages of this pump include:

  • Unique design of a multi-stage allows the end user to expand your pressure range by adding additional stages and even sizing up the motor if necessary, without pipe or foundation changes.
  • Seal Changes in Under an Hour.  The CR(N)-H cartridge seal can be replaced on-site without pump removal, or disassembly, or additional alignment.
  • It also has variable speed functionality, offering control of your pump system, while providing more flexibility and as much as 80% reduction of energy costs consumed.
