Abstract
Provided is a pump system that includes a primary pump and a secondary pump. The primary pump pumps a primary fluid. A pump unit of the primary pump includes an inner liner defining a primary fluid chamber. The inner liner is expandable and selectably removable from the primary pump. The pump unit further includes an outer liner that is disposed around the inner liner. An interior of the outer liner defines at least a portion of a secondary fluid chamber. The secondary pump pumps a secondary fluid into and out of the secondary fluid chamber, resulting in pumping of the primary fluid through the primary fluid chamber.
Claims20
A pump system, comprising:
- a primary pump that pumps a primary fluid, the primary pump comprising a pump unit comprising:
- an inner liner that is expandable, an interior of which defines a primary fluid chamber, the inner liner being selectably removable from the primary pump;
- and
- an outer liner disposed around the inner liner, an interior of the outer liner defining at least a portion of a secondary fluid chamber;
- and
- a secondary pump that pumps a secondary fluid, the secondary pump configured to operably pump the secondary fluid into and out of the secondary fluid chamber, resulting in pumping of the primary fluid through the primary fluid chamber.
A pump system, comprising:
- a primary pump that pumps a primary fluid, the primary pump comprising a first pump unit comprising:
- an inner liner that is expandable, an interior of which defines a primary fluid chamber, the primary fluid chamber comprising an inlet and an outlet;
- an inlet valve proximate the inlet;
- an outlet valve proximate the outlet, wherein the inner liner is removably attached to the inlet valve and the outlet valve;
- and
- an outer liner disposed around the inner liner, an interior of the outer liner defining at least a portion of a secondary fluid chamber;
- and
- a secondary pump that operably pumps a secondary fluid into and out of the secondary fluid chamber to pump the primary fluid between the inlet and the outlet.
A pump system, comprising:
- a primary pump that pumps a primary fluid and comprises a first pump unit, the first pump unit comprising:
- an inner liner that is expandable, an interior of which defines a primary fluid chamber, the primary fluid chamber comprising an inlet and an outlet, wherein the inner liner is selectably removable from the primary pump;
- an inlet valve proximate the inlet;
- an outlet valve proximate the outlet, wherein the inner liner is removably attached to the inlet valve and the outlet valve;
- and
- an outer liner disposed around the inner liner, an interior of the outer liner defining at least a portion of a secondary fluid chamber, the secondary fluid chamber comprising a first fluid port and a second fluid port;
- a secondary pump that pumps a secondary fluid, the secondary pump in fluid communication with the secondary fluid chamber of the first pump unit to operably pump the secondary fluid into the secondary fluid chamber, resulting in the compression and expansion of the inner liner of the first pump unit;
- and
- a secondary fluid sump in fluid communication with the secondary pump and in fluid communication with the secondary fluid chamber to receive the secondary fluid from the secondary fluid chamber, and the secondary fluid sump operably providing the secondary fluid to the secondary pump.
