Centrifugal separator

A centrifugal separator, comprising:

• a separator housing that includes a stationary chamber having a stationary chamber sidewall and a stationary chamber floor substantially closing an open bottom end of the stationary chamber sidewall, and the separator housing also including a mechanical floor below the stationary chamber floor;
• a horizontal plate located vertically between the stationary chamber floor and the mechanical floor, and a plurality of isolation mounts, the plate supported with respect to the mechanical floor by the plurality of isolation mounts;
• a bearing mounted to the plate with a bearing axis oriented vertically and fixed against horizontal movement with respect to the plate;
• a basket arranged to spin within the stationary chamber, the basket having a perforated surrounding sidewall;
• a motor arranged below the stationary chamber floor, the motor having a motor housing and an output shaft;
• a flexible coupling;
• a driveshaft connected to the output shaft by the flexible coupling, the driveshaft extending through the bearing to be journaled thereby, and extending through the stationary chamber floor and connected to the basket, the motor housing fastened to the mechanical floor, the motor housing arranged below the driveshaft;
• and comprising a substantially horizontal intermediate floor arranged between the mechanical floor and the plate, wherein the mechanical floor is supported from the intermediate floor and the plurality of isolation mounts are located between the plate and the intermediate floor.
