Abstract
A pump for providing a flow of fluid from a fluid source to a fluid destination. The pump includes a rotatable turbine, a first inlet port in fluid communication with the turbine, a first outlet port in fluid communication with the first inlet port, a second inlet port in fluid communication with the turbine, and a second outlet port in fluid communication with the second inlet port. The turbine pumps fluid from the fluid source into the first inlet port and out of the first inlet port into a reservoir. The turbine pumps fluid in the reservoir into the second inlet port and out of the second outlet port to the fluid destination.
Claims30
A pump for pumping fluid from a fluid source to a fluid destination, the pump comprising:
- a first inlet port adapted to be in fluid communication with the fluid source;
- a turbine having a central axis, the turbine adapted to rotate about the central axis, the turbine being in fluid communication with the first inlet port;
- a first outlet port in fluid communication with the turbine and the first inlet port, a first fluid flow path extending between the first inlet port and the first outlet port, the turbine adapted to cause fluid to flow through the first fluid flow path from the first inlet port to the first outlet port;
- a second inlet port adapted to be in fluid communication with fluid discharged from the first outlet port, the turbine being in fluid communication with the second inlet port;
- a second outlet port in fluid communication with the turbine and the second inlet port, a second fluid flow path extending between the second inlet port and the second outlet port, the second outlet port adapted to be placed in fluid communication with the fluid destination, the turbine adapted to cause fluid to flow through the second fluid flow path from the second inlet port to the second outlet port.
A pump for pumping fluid from a fluid source to a fluid destination, the pump comprising:
- a housing having an outlet port adapted to be placed in fluid communication with the fluid destination;
- a collar coupled to the housing, the collar including a bore in fluid communication with the outlet port of the housing;
- a turbine having a central axis, a plurality of inner bores in fluid communication with the collar, and a plurality outer fluid passages in fluid communication with the collar, the turbine being selectively rotatable about the central axis of the turbine;
- an end cap having a first inlet port in fluid communication with one or more of the inner bores of the turbine as the turbine rotates, an outlet port in fluid communication with one or more of the inner bores of the turbine as the turbine rotates, and a second inlet port in fluid communication with one or more of the outer fluid passages of the turbine as the turbine rotates.
A method for pumping fluid from a fluid source to a fluid destination, the method comprising:
- providing a pump having a selectively rotatable turbine, a first inlet port in fluid communication with the turbine and adapted to be placed in fluid communication with the fluid source, a first outlet port in fluid communication with the turbine and the first inlet port, a second inlet port in fluid communication with the turbine, and a second outlet port in fluid communication with the turbine and the second inlet port and adapted to be placed in fluid communication with the fluid destination;
- pumping fluid from the fluid source into the first inlet port of the pump and out of the first outlet port of the pump;
- pumping the fluid discharged from the first outlet port of the pump into the second inlet port of the pump and out of the second outlet port of the pump.
