Overview
PCA300 pumps feature a magnetically levitated impeller that is rotated independent of its stabilization functions. The pump offers continuous, steady flow without pressure pulsation. Its process-safe PTFE/PFA flow path is ideal for ultra-pure wet process applications. They are precisely controlled by electronically regulating the impeller speed.

Operation
![](https://cdn.wkfluidhandling.com/wp-content/media/operation-models/pca300_operation-diagram.jpg)
Fluid enters through the impeller eye and is accelerated by centrifugal force created by the impeller rotation. The impeller is rotated with magnetic coupling and levitated by a magnetic bearing system. These magnetic systems prolong pump life as there are no mechanical couplings or seals to wear and fail.
