The present invention is directed to a pump system. The pump system has a motor, a pump shaft, a pumping section, a connecting column, and a shaft isolator. The motor drives the pump shaft and has a bottom surface above a desired medium. The pumping section has a top surface that receives the pump shaft and pumps the desired medium to a predetermined instrument. The connecting column surrounds a predetermined portion of the pump shaft and connects the motor support and pumping section together. The shaft isolator is positioned between the connecting column and the pump shaft, and extends from the top surface of the pumping section to a predetermined height above the desired medium and below the bottom surface of the motor. The resulting pumped medium has an acceptable amount of entrained air that will not adversely affect the predetermined instrument.
