Claims21
A bypass system for a submersible pump, the submersible pump including a housing, a plurality of impeller stages disposed in the housing and aligned in series from a bottom impeller stage to a top impeller stage, each of the impeller stages having an impeller, the system comprising an impeller stage bypass hole extending through one of the impellers and a housing bypass hole extending through the housing radially outward from one of the impeller stages.
A submersible pump comprising:
- a housing;
- a plurality of impeller stages serially disposed in the housing from a bottom impeller stage to a top impeller stage, each of the impeller stages having an impeller;
- an impeller bypass hole extending through one of the impellers;
- and
- a housing bypass hole extending through the housing radially outwardly from one of the impeller stages.
A method of making a submersible pump, the pump including a housing, a plurality of impeller stages disposed in the housing and aligned in series from a bottom impeller stage to a top impeller stage, each of the impeller stages including an impeller, the method comprising forming an impeller bypass hole through one of the impellers and forming a housing bypass hole extending through the housing radially outward one of the impeller stages.
A submersible pumping system for pumping water from a well, the system comprising:
- a pump comprising:
- a housing;
- a plurality of impeller stages serially disposed in the housing from a bottom impeller stage to a top impeller stage, each of the impeller stages having an impeller;
- an impeller bypass hole extending through one of the impellers;
- and
- a housing bypass hole extending through the housing radially outwardly from one of the impeller stages;
- and
- a submersible motor operatively coupled to the pump.
