Fluid pump and method of manufacturing same

A process for manufacturing a fluid pump, comprising:

• forming an auger tube from a first synthetic polymer;
• forming a helical screw from a second synthetic polymer;
• forming an outlet end cap from a third synthetic polymer, obtaining a drive shaft having a first end and a second end, wherein the fluid pump comprises:
• the auger tube that comprises a first end and a second end, the helical screw that comprises a first end, a second end, and collar positioned toward the second end thereof, the outlet end cap that comprises a first end that defines a longitudinal bore partially therethrough, a second end that defines an aperture therethrough, a first shoulder, and a second shoulder, and an outlet tube having a first end in fluid communication with the longitudinal bore defined by the first end of the outlet end cap, a first bearing that defines a bore therethrough, a second bearing that defines a bore therethrough, and an adapter that defines a shoulder, coupling the drive shaft to the helical screw;
• coupling the first end of the outlet end cap to the second end of the auger tube;
• disposing the first bearing within the aperture defined by the second end of the outlet end cap;
• disposing the second bearing within the aperture defined by the second end of the outlet end cap;
• disposing the helical screw within the auger tube such that the first bearing is disposed between the collar of the helical screw and the first shoulder defined by the second end of the outlet end cap and the second end of the drive shaft extends at least partially through the bore defined by the first bearing and the bore defined by the second bearing;
• and coupling the first end of the adapter to the second end of the drive shaft such that the second bearing is disposed between the second shoulder defined by the second end of the outlet end cap and the shoulder defined by the adapter.

A fluid pump, comprising:

• an auger tube having a first end and a second end;
• a helical screw having a first end and a second end;
• an outlet end cap having a first end that defines a longitudinal bore partially therethrough, a second end that defines an aperture therethrough, and an outlet tube having a first end in fluid communication with the longitudinal bore defined by the first end of the outlet end cap;
• an inlet end cap having a first end, a second end, and that defines a longitudinal bore therethrough;
• a drive shaft having a first end and a second end;
• a bearing that defines a bore therethrough;
• an adapter that defines a shoulder, wherein:
• the first end of the drive shaft is coupled to the second end of the helical screw, the helical screw is disposed within the auger tube, the first end of the outlet end cap is coupled to the second end of the auger tube, the second end of the inlet end cap is coupled to the first end of the auger tube, a plurality of stand-off feet extends from the first end of the inlet end cap to define a plurality of fluid passages that permits a fluid to flow into the longitudinal bore defined by the inlet end cap when the plurality of stand-off feet abuts against a submerged surface, the second end of the drive shaft extends at least partially through the bore defined by the bearing, the second end of the outlet end cap defines a shoulder, a first end of the adapter is configured to be coupled to the second end of the drive shaft and disposed at least partially within the bore defined by the bearing, the bearing is at least partially disposed within the aperture defined by the second end of the outlet end cap and between the shoulder defined by the second end of the outlet end cap and the shoulder defined by the adapter, and wherein:
• the auger tube is formed from a first synthetic polymer, the helical screw is formed from a second synthetic polymer, the outlet end cap is formed from a third synthetic polymer, and the inlet end cap is formed by a fourth synthetic polymer.
