1. A staged peristaltic pump system configured to displace a working fluid, the system comprising:
- a system inlet;
a system outlet; and
a plurality of peristaltic pumps disposed serially between the system inlet and the system outlet, the plurality of peristaltic pumps configured such that a working fluid pressure change across any single pump is substantially the same as the working fluid pressure change across any other pump in the plurality of peristaltic pumps.

Abstract
Staged peristaltic pump systems and related methods are disclosed. A system may be configured such that the working fluid pressure differential across any individual stage of the system is smaller than the pressure across the entire system. In some embodiments certain components of each stage may be sealed from fluid communication with an external environment, though working fluid may be configured to cross the boundary of the seal. In some embodiments, stages may be pressurized with respect to an external environment.

166. A method of increasing the pressure of a working fluid in a staged peristaltic pump system, the method comprising:
-
displacing working fluid in stages along a flow path from a system inlet to a system outlet, wherein the working fluid is displaced by a plurality of peristaltic pumps disposed serially between the system inlet and the system outlet, the plurality of peristaltic pumps configured such that a working fluid pressure change across any single pump is substantially the same as the working fluid pressure change across any other pump in the plurality of peristaltic pumps. - View Dependent Claims (167, 168, 169, 171, 172, 173, 175, 183, 189, 190, 191)
