Applications; Pumped Liquids; Identification; Nameplate For Crk And Mtr - Grundfos CRK-Serie Montage- Und Betriebsanleitung

3. 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.
Warning
Do not use the pump for flammable liquids,
such as diesel oil and petrol.

3.1 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.
