Abstract: A pressure vessel and submerged electric motor pump system may include a pressure vessel and at least two motor-pump assemblies located within the pressure vessel. Each of the at least two motor-pump assemblies may include a submersible electric motor and a submersible pump in operable communication with the submersible electrical motor. The submersible pump may be configured to pump fluid from within the pressure vessel to without the pressure vessel. A method for pumping a fluid from a pressure vessel may include supplying a fluid to a pressure vessel, pumping the fluid with two or more submersible electric motor pumps located within the pressure vessel and discharging a pumped fluid from the pressure vessel.

Abstract: A vertically-disposed pump shaft is supported by an upward force against the pump shaft during periods of non use of the pump thereby off-loading bearings normally supportive of the shaft to prevent damage thereto when the pump is moved. Additionally, a lateral support is provided at a lower end of the pump to prevent lateral movement while permitting axial movement, thereby reducing stresses against the pump housing and other components.
