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.
Claims12
A surface-located pumping apparatus for pumping fluid from a fluid source, comprising:
- a pressure vessel having an inlet on one end adapted to be connected to the fluid source, and a discharge;
- a submersible pump disposed in the pressure vessel, the pump having an intake on one end and a discharge on another end;
- 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 on one end adapted to be connected to the fluid source, a discharge end opposite the inlet;
- a pump disposed in the pressure vessel, the pump having an intake on one end and a discharge on another end;
- and
- an motor located external to the pressure vessel, the motor constructed and arranged to operate the pump and having a shaft extending thereto.
