5. Product introduction
5.1 Applications
The Grundfos pumps, types CRK and MTR, are tank
mounted multistage centrifugal pumps designed for
the following applications:
•
liquid transfer in machine tools
• condensate transfer
• liquid transfer in industrial washing machines
• pressure boosting of cold or hot clean liquids
• similar applications.
5.2 Pumped liquids
Thin, non-explosive liquids, not containing fibres.
The liquid must not attack the pump materials
chemically.
When pumping liquids with a density and/or viscosity
higher than that of water, use motors with
correspondingly higher outputs, if required.
MTR version A pumps have a cast iron pump head.
In MTR version I and CRK version I pumps all parts
in contact with the pumped liquid are of stainless
steel EN/DIN 1.4301 or better.
