Operating and inlet pressure CR-H, CRN-H, CRE-H, CRNE-H Operating range of the shaft seal The operating range of the shaft seal depends on operating pressure, pump type, type of shaft seal and liquid temperature. The following curves apply to clean water and water with anti-freeze liquids. For selecting the right shaft seal, see List of pumped liquids on page 100.

Standard CR-H, CRN-H pumps are not suitable for the pumping of liquids above 248 °F (120 °C) for long periods. See the Grundfos "Custom-built Pumps" Product Guide for information about pumps for extreme temperatures and special conditions.
