Abstract
A pump includes a cylinder and a piston disposed within the cylinder to define a first chamber and a second chamber within the cylinder. The piston is configured to move within the cylinder to reduce a size of the first chamber to discharge material from the first chamber. The pump also includes a conduit system configured to direct fluid into the first chamber to aerate material in the first chamber.
Claims19
A pump, comprising:
- a first cylinder;
- a first piston disposed within the first cylinder to define a first chamber and a second chamber within the first cylinder, wherein the first piston is configured to move within the first cylinder to reduce a size of the first chamber to discharge material from the first chamber;
- a second cylinder;
- a second piston disposed within the second cylinder to define a third chamber and a fourth chamber within the second cylinder, wherein the second piston is configured to move within the second cylinder to reduce a size of the third chamber to discharge material from the third chamber;
- and
- a conduit system configured to direct fluid into the first chamber to aerate material in the first chamber, wherein the conduit system fluidly couples the fourth chamber and the first chamber to one another and is configured to direct fluid from the fourth chamber to the first chamber to aerate material in the first chamber.

A pump, comprising:
- a first cylinder having an inlet;
- a first piston disposed within the first cylinder to define a first chamber and a second chamber within the first cylinder, the first piston being movable within the first cylinder to reduce a size of the first chamber to discharge material from the first chamber and to increase a size of the second chamber;
- a second cylinder;
- a second piston disposed within the second cylinder to define a third chamber and a fourth chamber within the second cylinder;
- and
- a conduit system that directs fluid into the first chamber to aerate material in the first chamber, wherein conduit system is configured to direct the fluid adjacent to the inlet, wherein the conduit system fluidly couples the fourth chamber and the first chamber to one another and is configured to direct fluid from the fourth chamber to the first chamber to aerate material in the first chamber.
