Abstract
A suction chamber for use in a pumping system has a motor and a pump. The suction chamber is positioned between the motor and the pump in the pumping system and has a seal assembly. The seal assembly seals the shaft to prevent fluid from leaking through a motor end of the suction chamber. The seal assembly may be removed and replaced through the pump, or wet end of the suction chamber so that any parts, including thrust bearing chamber and/or the motor positioned on the motor end of the suction chamber are not moved during the removal and replacement of the sealing assembly. This permits removal and replacement of the sealing assembly without necessitating the need for realigning the motor, thrust bearing chamber and other parts on the motor side of the suction chamber which alleviates the risk of vibration that might occur due to the removal and then improper realignment of the motor, bearings and/or other equipment on the motor side of the suction chamber.
