Pumped liquids CR-H, CRN-H, CRE-H, CRNE-H Pumped liquids We recommend CR(E)-H, CRN(E)-H pumps for 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 may used, if required. Whether a pump is suitable for a particular liquid depends on a number of factors including 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)-H, CRN(E)-H pump types are suitable for pumping the following: CR(E)-H • Non-corrosive liquids For fluid transfer, circulation and pressure boosting of cold or hot, clean water or other non-corrosive liquids. CRN(E)-H • Industrial liquids In sytems where all parts in contact with the pumped liquid must be made of high-grade stainless steel. 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 <strong>guide</strong> 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 the following may affect the chemical resistance of a specific pump version: • concentration of the pumped liquid • liquid temperature • pressure. Safety precautions must be observed when pumping dangerous liquids. The notes in this list apply to the table on the following page. 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 <strong>cr</strong>ystallization/precipitation in shaft seal 1 The pumped liquid is highly flammable. 2 The pumped liquid is combustible. 3 Insoluble in water. 4 Low self-ignition point. 100
