Abstract
A submersible pumping system includes a pump assembly that is connected to a motor assembly. The pump assembly includes a pump intake having an intake hole, a pump housing connected to the pump intake and a pump discharge head connected to the pump housing. An intake seal device is connected to the pump intake and seals the pump intake prior to the initial use of the pump assembly. To further isolate the pump assembly while dormant, an outlet seal device can be fitted to the pump discharge head to isolate the pump assembly from the reservoir fluid in the production tubing.
