To meet the extreme temperature requirements of the oil industry, Cardinal pumps are rated for continuous duty operating ranges from -40 to 212°F (-40 to 100°C). Other features include the ability to permit thermosiphon flow when the pump is not operating, allowing natural convection when the pump is shut off. The pumps offer a split-casing design with heavy-duty Class 30 cast iron pump casting, motor enclosure, impellers and volutes. Large-thrust face-sleeve bearings extend life, minimize wear and reduce maintenance, says the company.
