What is claimed is: 1. A pumping system, comprising: a first section, comprising: a first housing having an axial bore formed therethrough and a protruding member formed on one end of the first housing; and a first shaft arranged within the axial bore of the first housing; and a second section, comprising: a second housing having an axial bore formed therethrough and a recess formed on one end of the second housing for receiving the protruding member of the first housing; and a second shaft arranged within the axial bore of the second housing, wherein the protruding member in the first section has a slanted surface on an end face thereof to minimize trapping air in an oil held in the recess in the second section when the first section and the second section are joined. 2. The pumping system of claim 1, wherein the first section is one selected from a motor and a motor protector, wherein the second section is one selected from a motor and a motor protector. 3. The pumping system of claim 2, wherein the first section and the second section are pre-filled with motor oil. 4. The pumping system of claim 1, further comprising a shaft coupler for coupling the first shaft and the second shaft. 5. The pumping system of claim 4, wherein the shaft coupler is arranged on the first shaft. 6. The pumping system of claim 5, wherein the shaft coupler is releasably attached to the first shaft by a retaining clip. 7. The pumping system of claim 1, further comprising a seal disposed on the first housing and adapted to engage the first shaft. 8. The pumping system of claim 7, wherein the seal is located proximate the lowest point of the first housing. 9. The pumping system of claim 1, further comprising a compensator connected to an end of the first or second section, wherein the compensator compensates for the oil volume change in the section to which the compensator is connected. 10. The pumping system of claim 9, wherein the compensator comprises: a compensator housing having an open end for connecting to the first or second section, a closed end, and an axial bore therethrough; and a flexible bladder arranged within the compensator housing and connected to the open end of the compensator housing. 11. The pumping system of claim 10, wherein the compensator is connected to the first or second section by a tube. 12. The pumping system of claim 1, wherein the first section further comprises a communication valve assisted by a spring or an elastic element. 13. The pumping system of claim 12, wherein the second section further comprises a valve actuator that opens the communication valve. 14. The pumping system of claim 1, wherein the protruding member in the first section comprises a bolt-on bulkhead plate in which at least one protruding element is installed. 15. The pumping system of claim 14, wherein the protruding element is at least one selected from an electrical terminal, a gauge terminal, a thermal couple, and a valve component. 16. The pumping system of claim 15, wherein the protruding terminal is sealed with a rubber grommet. 17. The pumping system of claim 1, wherein the first section further comprises an anti-rotation ring that is radially installed using a first anti-rotation element, wherein the first anti-rotation element protrudes into a recess in the first housing, wherein the anti-rotation ring has a second anti-rotation element that engages a bearing. 18. The pumping system of claim 17, wherein each of the first and the second anti-rotation elements is one selected from a screw, a pin, and a key. 19. The pumping system of claim 17, wherein the recess allows fluid to flow past the anti-rotation ring.
