Abstract
Disclosed herein are a dual inlet volute with an impeller and pump for same, and related methods. In one form a pump is provided comprising a motor configured to rotate a shaft, an impeller operatively coupled to the shaft, and a volute housing the impeller, the volute having a first inlet, a second inlet, and a discharge in fluid communication with the first and second inlets.
Claims26
A pump comprising:
- a motor configured to rotate a shaft;
- an impeller operatively coupled to the shaft;
- and
- a fluid chamber housing the impeller, the fluid chamber having a top, a bottom and a side positioned between the top and bottom, the fluid chamber having a first inlet extending through the top of the fluid chamber, a second inlet extending through the bottom of the fluid chamber, and a discharge in fluid communication with the first and second inlets and extending through the side of the fluid chamber radially outward of the impeller,
- wherein the fluid chamber is configured to be submerged in a fluid such that rotation of the impeller draws fluid into the fluid chamber via the first inlet and the second inlet and forces the fluid out the discharge,
- wherein the bottom of the fluid chamber is configured to engage a surface and space the second inlet away from the surface to allow fluid to flow therethrough.
3 more elements
A volute comprising:
- a first cavity containing a first impeller portion;
- a second cavity containing a second impeller portion;
- a third cavity connecting the first cavity and the second cavity to a discharge;
- a first inlet extending through a top surface of the volute and in fluid communication with the first impeller portion;
- and
- a second inlet extending through a bottom surface of the volute and in fluid communication with the second impeller portion,
- wherein the volute is configured to be submerged in a fluid such that the fluid enters the first cavity via the first inlet and enters the second cavity via the second inlet;
- and
- wherein the bottom surface of the volute is configured to engage a surface and space the second inlet away from the surface to allow the fluid to flow therethrough.
6 more elements
A method of pumping fluid with a pump, the method comprising:
- operating a motor to rotate a double impeller within a fluid chamber, the double impeller having a first impeller and a second impeller, the fluid chamber being submerged in a fluid and having a top, a bottom and a side positioned between the top and bottom;
- creating a first flow with the first impeller, the first flow extending through a first inlet extending through the top of the fluid chamber;
- creating a second flow with the second impeller, the second flow extending through a second inlet extending through the bottom of the fluid chamber;
- directing the first flow and the second flow out a single discharge extending through a side of the fluid chamber radially outward of the double impeller,
- wherein the bottom of the fluid chamber is configured to engage a surface and space the second inlet away from the surface to allow fluid to flow therethrough.
2 more elements
A method of manufacturing a pump comprising:
- providing a pump having a fluid chamber configured to be submerged in a fluid and having a top, a bottom and a side positioned between the top and bottom, a first inlet extending through the top of the fluid chamber, a second inlet extending through the bottom of the fluid chamber, and a discharge extending through the side of the fluid chamber, the bottom of the fluid chamber configured to engage a surface and space the second inlet away from the surface to allow fluid to flow therethrough;
- and
- providing a dual flow impeller having a first impeller portion positioned proximate the first pump inlet to pump fluid through the first inlet, and having a second impeller portion positioned proximate the second pump inlet to pump fluid through the second inlet.
