    Abstract: Some embodiments of the invention provide a pump including a pump chamber, a shaft at least partially positioned in the pump chamber, an impeller coupled to the shaft, and a seal coupled to the shaft. The pump also includes a wet seal chamber. The wet seal chamber can include a separator with a disc and a resilient member. The disc includes one or more slots through which fluid pressure from the pump chamber is transferred to the resilient member.
