Abstract
A surface pump assembly having a pressure vessel containing a submersible pump and an industrial motor located at least partially external to the pressure vessel having a shaft or seal thrust chamber extending at least partially into the pressure vessel to connect to pump. The pressure vessel has an inlet connected to a fluid source and one or more bleed off or pressure relief valves. The pump has an intake to receive the fluid and a discharge connected to a discharge conduit.
Claims15
A surface-located pumping apparatus for pumping fluid from a fluid source, comprising:
- a pressure vessel having an inlet adapted to be connected to the fluid source;
- a submersible pump disposed in the pressure vessel, the pump having an intake disposed in an interior of the pressure vessel and a discharge isolated from the fluid in the interior of the pressure vessel;
- and
- an industrial motor located adjacent the pressure vessel and having a shaft or seal thrust chamber extending at least partially into the pressure vessel to connect to the pump.
An apparatus for pumping fluid down a well, comprising:
- a flow line feed pump having an intake connected to a source of fluid and an outlet for transferring the fluid out the outlet at a selected feed pressure;
- a pressure vessel connected to the fluid source by an inlet on one end;
- a submersible pump contained within the pressure vessel and connected to a motor located at least partially outside of the pressure vessel and having a shaft or seal thrust chamber sealably extending at least partially into the pressure vessel, the pump having an intake disposed in the pressure vessel and a discharge connected to a discharge conduit sealably extending through the pressure vessel;
- and
- a valve disposed at the discharge end of the pressure vessel for bleeding off any accumulation of gases.
A surface-located pumping apparatus for pumping fluid from a fluid source, comprising:
- a sealed vessel having an inlet adapted to be connected to the fluid source;
- a pump disposed in the sealed vessel, the pump having an intake and having a discharge outside the pressure vessel;
- and
- a motor located external to the pressure vessel, the motor constructed and arranged to operate the pump and having a shaft extending thereto.
A surface-located pumping apparatus for pumping fluid from a fluid source, comprising:
- a sealed vessel having an inlet adapted to be connected to the fluid source;
- a single pump disposed in the pressure vessel, the pump having an intake disposed in the fluid within the sealed vessel and a discharge isolated from the fluid within the sealed vessel;
- and
- a motor located external to the pressure vessel, the motor constructed and arranged to operate the pump and having a shaft extending thereto.
A method of pumping a fluid supplied from a source, comprising:
- providing a sealed vessel and a pump having an intake disposed in an interior of the vessel;
- supplying the fluid from the source to an inlet of the vessel;
- operating the pump, thereby drawing the fluid in the vessel to the intake of the pump, the pump having a motor located external to the sealed vessel;
- and
- transporting the fluid through a fluid path to a discharge while isolating the fluid in the path from the fluid in the vessel.
