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 with a first fluid. The wet seal chamber can include a bladder that compresses to compensate for volumetric expansion of the first fluid. The wet seal chamber substantially prevents fluid from contacting the seal in order to prolong a life of the seal.
