Pumped liquids CR, CRI, CRN, CRE, CRIE, CRNE Pumped liquids Thin, non-explosive liquids, not containing solid particles or fibers. The liquid must not chemically attack the pump materials. When pumping liquids with a density and/or viscosity higher than that of water, oversized motors must be used, if required. Whether a pump is suitable for a particular liquid depends on a number of factors of which the most important are the chloride content, pH value, temperature and content of chemicals, oils, etc. Please note that aggressive liquids (e.g. sea water and some acids) may attack or dissolve the protective oxide film of the stainless steel and thus cause corrosion. The CR(E), CRI(E), CRN(E) pump types are suitable for the following liquids: CR(E), CRI(E) • Non-corrosive liquids. For liquid transfer, circulation and pressure boosting of cold or hot clean water. CRN(E) • Industrial liquids. In systems where all parts in contact with the liquid must be made of high-grade stainless steel. CRT(E) • Saline liquids. • Hypochlorites. • Acids. For saline or chloride-containing liquids such as sea water or oxidizing agents such as hypochlorites, CRT(E) pumps of titanium are available. See separate product guide on CRT(E). List of pumped liquids A number of typical liquids are listed on the following pages. Other pump versions may be applicable, but those stated in the list are considered to be the best choices. The table is intended as a general guide only, and cannot replace actual testing of the pumped liquids and pump materials under specific working conditions. The list should, however, be applied with some caution as factors such as • concentration of the pumped liquid, • liquid temperature or • pressure may affect the chemical resistance of a specific pump version. Safety precautions must be made when pumping dangerous liquids. Notes D Often with additives. Density and/or viscosity differ from that of water. E Allow for this when calculating motor output and pump performance. Pump selection depends on many factors. F Contact Grundfos. H Risk of crystallization/precipitation in shaft seal 1 The pumped liquid highly inflammable. 2 The pumped liquid is combustible. 3 Insoluble in water. 4 Low self-ignition point. 74
