End-of-Life Information

Grundfos MS6000 must be disposed of according to local regulations by using a public or private waste collection service. If this is not possible, contact the nearest Grundfos company or service workshop.


Safety risks

Safety risk related to materials used

  • MS6000 contains motor liquid with monopropylene glycol.
  • Hermetically sealed stator with embedding material – risk of explosion if exposed to temperature > 120 deg C.
  • Grinding in SS poses risk of dust with Cr and Ni.

Safety risk related to handling the product

  • Electrically burned motors can contain health hazardous substances formed by burning of various insulation materials.
  • Motor and motor liquid can contain substances present in the media it has been in (pay attention in case of radioactive media – biological growth etc.)


Disassembly of the product

  • Submersible motor can be disassembled into main components using standard tools.
  • Shaft can be pressed out of rotor core.
  • Stator + rotor core can be recycled by use of shredder technology to separate the different materials, copper, SS, electro steel and insulation materials.
