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…
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.
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.
