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. The wet seal chamber substantially prevents fluid from contacting the seal in order to prolong a life of the seal.

The pump of claim 1, wherein a first pressure in the wet seal chamber is higher than a second pressure at the inlet of the pump. 3. The pump of claim 1, wherein the wet seal chamber is positioned adjacent to the impeller. 4. The pump of claim 1, wherein the resilient member is a diaphragm. 5. The pump of claim 1, wherein the resilient member includes a bladder enclosing a fluid. 6. The pump of claim 1, wherein the resilient member decreases a volume of the wet sea chamber in order to increase a pressure in the wet seal chamber. 7. A pump comprising: a pump housing having a first housing portion and a second housing portion that is removably coupled to the first housing portion;a pump chamber including an inlet and an outlet;a shaft at least partially positioned in the pump chamber;an impeller coupled to the shaft, the impeller residing in the pump chamber;a seal coupled to the shaft; anda wet seal chamber positioned between the first housing portion and the second housing portion defining a reservoir for holding a first fluid having a first fluid pressure, the wet seal chamber including a separator for separating the wet seal chamber from the pump chamber, the separator including a resilient member that adjusts to increase the first fluid pressure by reducing a volume of the reservoir upon a second fluid pressure in the pumping chamber being greater than the first fluid pressure in the reservoir. 8. The pump of claim 7, wherein the first fluid pressure is higher than the second fluid pressure. 9. The pump of claim 7, wherein the separator further includes a disc, the disc including at least one slot through which the second fluid pressure from the pump chamber is transferred to the resilient member. 10. The pump of claim 9, wherein the resilient member includes at least one rib to inhibit the resilient member from blocking the at least one slot. 11. The pump of claim 7, wherein the resilient member is non-integral with the pump housing. 12. The pump of claim 7, wherein the resilient member includes a diaphragm. 13. The pump of claim 7, wherein the resilient member includes a ring and a bladder, the bladder enclosing a third fluid. 14. The pump of claim 13, wherein the bladder is molded onto the ring. 15. The pump of claim 7, wherein the resilient member includes an impermeable membrane. 16. The pump of claim 7, wherein the resilient member adjusts to decrease the first fluid pressure by increasing a volume of the reservoir upon the second fluid pressure in the pumping chamber being less than the first fluid pressure in the reservoir. 17. A wet seal chamber for a pump, the pump including a first housing portion and a second housing portion having an inlet, an outlet and a pump chamber, the pump including a shaft at least partially positioned in the pump chamber, and an impeller coupled to the shaft, the wet seal chamber comprising: a separator including a disc and a resilient member;a seal for coupling to the shaft; anda back wall;the resilient member and the back wall defining a reservoir for enclosing a first fluid having a first fluid pressure, the separator positioned between the pump chamber having a second fluid and the reservoir, the resilient member being deformable to increase the first fluid pressure by reducing a volume of the reservoir, andthe wet seal chamber positionable between the first housing portion and the second housing portion as a drop-in replacement for the pump. 18. The wet seal chamber of claim 17, wherein the resilient member deforms when a second fluid pressure of the second fluid in the pumping chamber is greater than the first fluid pressure of the first fluid in the reservoir. 19. The wet seal chamber of claim 18, wherein the disc includes at least one slot through which the second fluid pressure from the pump chamber is transferred to the resilient member. 20. The wet seal chamber of claim 19, wherein the resilient member includes at least one rib to inhibit the resilient member from blocking the at least one slot. 21. The wet seal chamber of claim 17, wherein the resilient member includes a diaphragm. 22. The wet seal chamber of claim 17, wherein the resilient member includes a bladder enclosing a third fluid.
