A centrifugal pump, and components thereof, operable at high speeds, is described under the present disclosure. A hard polymer sleeve can be applied to certain surfaces of a seal casing within the pump. If the sleeve is applied along surfaces near the center shaft, then the hard polymer will withstand the forces and pressures of the system. The hard polymer might not be used along the outer diameter, farther from the shaft, because velocities are higher the further out one goes. The current disclosure allows for the use of fluoropolymer in the lining sleeve. The benefits of fluoropolymer have been unavailable in high speed centrifugal pumps because the forces are too great on the periphery of the seal casing. However, the lower speeds along the interior, near the shaft, allow fluoropolymer to be used.
