A White Knight PCA300 centrifugal pump system was tested to determine how its use affects the size distribution of particles in Semi-Sperse® 12 slurry. The slurry was circulated until it passed through the pump approximately 1,000 times. After 1,000 turnovers, no change in the mean working particle size distribution was observed with DLS…
This report compares pressure and flow pulsations from a White Knight closed-loop control system and Levitronix system and evaluates their effect on the retention efficiency of a membrane filter. The White Knight system featured a PSA060 bellows pump; the Levitronix system used a BPS-4 centrifugal pump.
A White Knight PXASD060 bellows pump and Levitronix BPS600 centrifugal pump were run simultaneously in identical recirculation systems. The bath temperature was recorded eight hours. White Knight’s pump maintained a stable fluid temperature. The centrifugal pump heated the fluid bath significantly.
