Abstract
A pump assembly which includes a prop head which is driven by a rotor that is located in a housing to which the pump head is attached. The pump head includes a drive gear and a driven gear. The drive gear is coupled to the rotor by a shaft which is received at opposite ends by a bearing located in a closed end of the rotor housing and a bearing which is located in the pump head.
Claims56
A pump assembly, comprising:
- a frame;
- a stator coupled to the frame;
- a rotor associated with the stator and configured to include a bore;
- a housing configured to define a cavity in which the rotor is disposed, the cavity having a closed end and an open end;
- a first bearing secured in the closed end of the housing;
- a pump element disposed adjacent to and driven by the rotor and stator;
- and
- a solid shaft coupled to the pump element, disposed within and extending through the bore of the rotor, and journaled in the first bearing.

A pump assembly, comprising:
- a frame;
- a stator coupled to the frame;
- a rotor associated with the stator;
- a housing configures to define a cavity in which the rotor is disposed, the cavity including an open end;
- a solid shaft coupled to the rotor;
- a pump element coupled to the solid shaft and driven by the rotor and stator and including a body attached to the housing;
- and
- an alignment spacer adjacent the open end of the housing and the body of the pump element, the spacer reducing lateral shifting of the pump element relative to the housing.
