Abstract

The present invention provides a removable fluid removal pump filter for mounting on a fluid intake housing of a fluid removal pump having a fluid intake housing coupled to a pump shaft coupled to a head assembly having a pump handle and a discharge port. The removable fluid removal pump filter includes: a first member and a second member, wherein the second member is coupled to the first member and extends toward the proximal end of the first member. Methods of using the removable fluid removal pump filter are also disclosed.

Claims (43)

1. A removable fluid removal pump filter for mounting on a fluid intake housing of a fluid removal pump having a fluid intake housing coupled to a pump shaft coupled to a head assembly having a pump handle and a discharge port; the removable fluid removal pump filter comprising:

a first member having a first surface, a second surface, a proximal end, and a distal end,

wherein the first member comprises an opening at the proximal end,

wherein the second surface of the first member comprises a first internal diameter at the proximal end, a second internal diameter adjacent to the first internal diameter, and a third internal diameter adjacent to the second internal diameter and extending to the distal end,

wherein the first internal diameter is greater than the second internal diameter,

wherein the second internal diameter is greater than the third internal diameter,

wherein the first member comprises one or more sets of apertures on the first surface at the distal end;

a second member having a first surface and a second surface,

wherein the first surface of the second member is directly coupled to the distal end of the first member to form a solid tray with one or more edges that each independently extends upward towards the proximal end of the first member and the one or more edges extend around the distal end of the first member, and

wherein the first surface of the second member is planar with the distal end of the first member.

2. The removable fluid removal pump filter of claim 1 , wherein the first member is cylindrical.

3. The removable fluid removal pump filter of claim 1 , wherein the one or more sets of apertures at the distal end comprise two sets of apertures spaced around the distal end of the first member.

4. The removable fluid removal pump filter of claim 3 , wherein the one or more sets of apertures at the distal end comprise two sets of apertures oppositely spaced around the distal end of the first member.

5. The removable fluid removal pump filter of claim 1 , wherein the tray is a rectangular-shaped tray.

6. The removable fluid removal pump filter of claim 1 , wherein the tray is a circular-shaped tray.

7. The removable fluid removal pump filter of claim 1 , wherein the tray is a polygonal-shaped tray.

8. The removable fluid removal pump filter of claim 1 , wherein the fluid is water.

9. A removable fluid removal pump filter for mounting on a fluid intake housing of a fluid removal pump having a fluid intake housing coupled to a pump shaft coupled to a head assembly having a pump handle and a discharge port; the removable fluid removal pump filter comprising:

a cylindrical first member having a first surface, a second surface, a proximal end, and a distal end,

wherein the cylindrical first member comprises an opening at the proximal end,

wherein the second surface of the cylindrical first member comprises a first internal diameter at the proximal end, a second internal diameter adjacent to the first internal diameter, and a third internal diameter adjacent to the second internal diameter and extending to the distal end,

wherein the first internal diameter is greater than the second internal diameter,

wherein the second internal diameter is greater than the third internal diameter;

wherein the cylindrical first member comprises one or more sets of apertures on the first surface at the distal end;

a second member having a first surface and a second surface,

wherein the first surface of the second member is directly coupled to the distal end of the cylindrical first member to form a solid tray with one or more edges that each independently extends upward towards the proximal end of the cylindrical first member and the one or more edges extend around the distal end of the cylindrical first member, and

wherein the first surface of the second member is planar with the distal end of the cylindrical first member.

10. The removable fluid removal pump filter of claim 9 , wherein the one or more sets of apertures at the distal end comprise two sets of apertures spaced around the distal end of the cylindrical first member.

11. The removable fluid removal pump filter of claim 10 , wherein the one or more sets of apertures at the distal end comprise two sets of apertures oppositely spaced around the distal end of the cylindrical first member.

12. The removable fluid removal pump filter of claim 9 , wherein the tray is a rectangular-shaped tray.

13. The removable fluid removal pump filter of claim 9 , wherein the fluid is water.

14. A removable fluid removal pump filter for mounting on a fluid intake housing of a fluid removal pump having a fluid intake housing coupled to a pump shaft coupled to a head assembly having a pump handle and a discharge port; the removable fluid removal pump filter comprising:

a cylindrical first member having a first surface, a second surface, a proximal end, and a distal end,

wherein the cylindrical first member comprises an opening at the proximal end,

wherein the second surface of the cylindrical first member comprises a first internal diameter at the proximal end, a second internal diameter adjacent to the first internal diameter, and a third internal diameter adjacent to the second internal diameter and extending to the distal end,

wherein the first internal diameter is greater than the second internal diameter,

wherein the second internal diameter is greater than the third internal diameter,

wherein the cylindrical first member comprises two sets of apertures on the first surface and oppositely spaced around the distal end of the cylindrical first member;

a second member having a first surface and a second surface,

wherein the first surface of the second member is directly coupled to the distal end of the cylindrical first member to form a solid rectangular-shaped tray with one or more edges that each independently extends upward towards the proximal end of the cylindrical first member and the one or more edges extend around the distal end of the cylindrical first member,

wherein the first surface of the second member is coupled to the distal end of the cylindrical first member to form a solid rectangular shaped tray, and

wherein the first surface of the second member is planar with the distal end of the cylindrical first member.

15. The removable fluid removal pump filter of claim 14 , wherein the fluid is water.
