CLAIMS

WHAT IS CLAIMED IS:

1. A lubrication system for a frac pump, said lubrication system comprising:

a lubrication system housing;

a lubricant tank held by the lubrication system housing and configured to hold a lubricant;

a heating device held by the lubrication system housing, the heating device being fluidly connected to the lubricant tank such that the heating device is configured to heat the lubricant;

a cooling device held by the lubrication system housing, the cooling device being fluidly connected to the lubricant tank such that the cooling device is configured to cool the lubricant; and

a filtration device held by the lubrication system housing, the filtration device being fluidly connected to the lubricant tank such that the filtration device is configured to filter the lubricant,

wherein the lubrication system housing is configured to be at least one of mounted to a frac pump housing of the frac pump or held within the frac pump housing.

2. The lubrication system of claim 1, wherein the lubrication system housing, the lubricant tank, the heating device, the cooling device, and the filtration device are contained within the frac pump housing.

3. The lubrication system of claim 1, wherein the lubrication system housing is mounted to an exterior of the frac pump housing such that the lubricant tank, the heating device, the cooling device, and the filtration device are held on the exterior of the frac pump housing.

4. The lubrication system of claim 1 , wherein the frac pump is configured to be held by a frac pump platform, the lubrication system housing being mounted to the frac pump housing such that the lubricant tank, the heating device, the cooling device, and the filtration device are held on the frac pump platform underneath the frac pump.

5. The lubrication system of claim 1 , further comprising a lubricant pump configured to move lubricant between the lubricant tank, the heating device, the cooling device, the filtration device, and the frac pump.

6. The lubrication system of claim 1, further comprising a control system configured to monitor and control at least one of a temperature of the lubricant, a pressure of the lubricant, a quality of the lubricant, a flow rate of the lubricant, or operation of a pump of the lubrication system.

7. The lubrication system of claim 1, wherein the lubricant tank comprises an outlet fluidly connected to a lubricant circuit of the frac pump and configured to deliver a flow lubricant to the lubricant circuit, the lubricant tank comprising an inlet fluidly connected to the lubricant circuit and configured to receive a flow of the lubricant from the lubricant circuit.

8. The lubrication system of claim 1, wherein the heating device is at least partially contained within the lubricant tank.

9. A frac pump comprising;

a fluid end;

a power end operatively connected to the fluid end, the power end comprising a power end housing; and

a lubrication system fluidly connected to the power end for delivering a lubricant to the power end, the lubrication system comprising a lubrication system housing and a lubricant tank held by the lubrication system housing, the lubrication system comprising a heating device held by the lubrication system housing and configured to heat the lubricant, the lubrication system comprising a cooling device held by the lubrication system housing and configured to cool the lubricant, the lubrication system comprising a filtration device held by the lubrication system housing and configured to filter the lubricant,

wherein the lubrication system housing is at least one of mounted to the power end housing of the frac pump or held within the power end housing.

10. The frac pump of claim 9, wherein the lubrication system housing, the lubricant tank, the heating device, the cooling device, and the filtration device are contained within the power end housing.

11. The frac pump of claim 9, wherein the lubrication system housing is mounted to an exterior of the power end housing such that the lubricant tank, the heating device, the cooling device, and the filtration device are held on the exterior of the power end housing.

12. The frac pump of claim 9, wherein the frac pump is configured to be held by a frac pump platform, the lubrication system housing being at least one of mounted to the power end housing of the frac pump or held within the power end housing such that the lubricant tank, the heating device, the cooling device, and the filtration device are held on the frac pump platform underneath the frac pump.

13. The frac pump of claim 9, wherein the lubrication system further comprises a lubricant pump configured to move lubricant between the lubricant tank, the heating device, the cooling device, the filtration device, and the frac pump.

14. The frac pump of claim 9, wherein the lubrication system further comprises a control system configured to monitor and control at least one of a temperature of the lubricant, a pressure of the lubricant, a quality of the lubricant, a flow rate of the lubricant, or operation of a pump of the lubrication system.

15. The frac pump of claim 9, wherein the power end comprises a lubricant circuit and the lubricant tank comprises an outlet fluidly connected to the lubricant circuit and configured to deliver a flow lubricant to the lubricant circuit, the lubricant tank comprising an inlet fluidly connected to the lubricant circuit and configured to receive a flow of the lubricant from the lubricant circuit.

16. The frac pump of claim 9, wherein the heating device of the lubrication system is at least partially contained within the lubricant tank.

17. A frac pump system comprising:

a platform;

a frac pump held on the platform, the frac pump comprising a fluid end and a power end operatively connected to the fluid end; and

a lubrication system fluidly connected to the power end of the frac pump for supplying the power end with a lubricant, the lubrication system comprising a housing, a lubricant tank held by the housing, a heating device held by the housing, a cooling device held by the housing, and a filtration device held by the housing, wherein the housing of the lubrication system is mounted on the platform such that the lubricant tank, the heating device, the cooling device, and the filtration device are held on the platform.

18. The frac pump system of claim 17, wherein the platform comprises at least one of a skid, a trailer, a fixture, a frame, or a manifold.

19. The frac pump system of claim 17, wherein the housing of the lubrication system is mounted on the platform such that the lubricant tank, the heating device, the cooling device, and the filtration device are held on the platform underneath the frac pump.

20. The frac pump system of claim 17, wherein the housing of the lubrication system is at least one of mounted to the frac pump housing or held within the frac pump.
