Abstract

Embodiments of the invention provide a sump pump system that pumps fluid. The system can include a base with one or more inlets and one or more outlet. The system can also include a first cartridge coupled to the base and removable from the base. The first cartridge can include a first electric motor. The system can further include a second cartridge coupled to the base and removable from the base. The second cartridge can include a second electric motor. The first cartridge and/or the second cartridge can be capable of operating at any given time in order to propel fluid from inlets to the outlets.

Claims

1. A sump pump system that pumps fluid, the sump pump system comprising:

a base including a first through hole and a second through hole, and at least one fluid inlet and at least one fluid outlet;

a first cartridge extending into the first through hole and mechanically coupled to the base, the first cartridge removable from the base, the first cartridge including a first electric motor;

a second cartridge extending into the second through hole and mechanically coupled to the base, the second cartridge removable from the base, the second cartridge including a second electric motor;

at least one flexible gasket including a flexible flap portion, a portion of the at least one flexible gasket coupled to at least one of the first cartridge, the second cartridge, and the base with the flexible flap portion extending away from the at least one of the first cartridge and the second cartridge and at least partially covering the at least one fluid outlet; and

at least one of the first cartridge and the second cartridge being capable of operating at any given time in order to propel fluid from the at least one fluid inlet, through the base, and to the at least one fluid outlet.

2. The sump pump system of claim 1, and further comprising at least one float switch;

and wherein at least one of the first cartridge and the second cartridge is activated based on a fluid level monitored by the at least one float switch.

3. The sump pump system of claim 1, wherein the first electric motor is powered by a direct current power source and the second electric motor is powered by an alternating current power source.

4. The sump pump system of claim 3, wherein the direct current power source is a battery.

5. The sump pump system of claim 3, wherein the alternating current power source is a mains power supply.

6. The sump pump system of claim 1, and further comprising at least one flap positioned adjacent to the at least one outlet.

7. The sump pump system of claim 1, and further comprising at least one collector positioned adjacent to the at least one outlet.

8. The sump pump system of claim 7, wherein the at least one collector includes an aperture enabling a fluid to enter the at least one collector.

9. The sump pump system of claim 8, wherein the aperture is aligned with a shaft of one of the first electric motor and the second electric motor.

10. The sump pump system of claim 1, wherein the first cartridge includes a first impeller driven by the first electric motor and the second cartridge includes a second impeller driven by the second electric motor.

11. The sump pump system of claim 1, wherein at least one of the first cartridge and the second cartridge is mechanically coupled to the base using a quick connect device.

12. The sump pump system of claim 1, and further including an outlet conduit system coupleable to the at least one outlet.

13. A sump pump system that pumps fluid, the sump pump system comprising:

a base including at least one inlet and at least one outlet;

a first sealed cartridge removably coupled to the base, the first sealed cartridge including a first electric motor and a first impeller extending from the first sealed cartridge;

a second sealed cartridge removably coupled to the base, the second sealed cartridge including a second electric motor and a second impeller extending from the second sealed cartridge;

a power supply in electrical communication with the first electric motor and the second electric motor;

at least one flexible gasket including a flexible flap portion, a portion of the at least one flexible gasket coupled to at least one of the first sealed cartridge and the second sealed cartridge, with the flexible flap portion extending away from the at least one of the first sealed cartridge and the second sealed cartridge and at least partially covering the at least one outlet; and

each of the first sealed cartridge and the second sealed cartridge being removable from the base without the use of tools and using a quick connect device, each of the first sealed cartridge and the second sealed cartridge being removable from the base without interrupting the electrical communication between the power supply and each of the first electric motor and the second electric motor.

14. The sump pump system of claim 13, wherein the power supply includes a float switch.

15. The sump pump system of claim 13, wherein the base includes a through hole sized to receive the impeller.

16. A sump pump system that pumps fluid, the sump pump system comprising:

a base including at least one outlet;

a sealed cartridge coupled to the base, the sealed cartridge including an electric motor and an impeller extending from the sealed cartridge; and

a flexible gasket including a flexible flap portion, a portion of the flexible gasket coupled to the cartridge, with the flexible flap portion extending away from the cartridge and at least partially covering the at least one outlet.

17. The sump pump system of claim 16, and further comprising at least one collector in fluid communication with one of the at least one outlet.

18. The sump pump system of claim 17, wherein the at least one collector includes a slope.

19. The sump pump system of claim 18, wherein the slope directs fluid from the at least one collector to the at least one outlet.

20. The sump pump system of claim 16, wherein the base includes a through hole sized to receive the impeller.

21. The sump pump system of claim 16, wherein the cartridge is coupled to the base using a quick connect device.
