High Temperature Twin Screw Pumps
High temperature applications present many engineering problems. Thermal growth of piping and vessels, coupled with typically lower viscosities at high temperature, has made centerline mounted centrifugal pumps the primary choice in hot applications. Two screw pumps offer extended viscosity ranges, can handle entrained gases, and require less inlet pressure than centrifugal pumps. Two screw pumps have earned a reputation of reliability over several decades of high temperature service in demanding applications.
