SYSTEM, DEVICE AND METHOD FOR FLUID PUMPING, HEAT EXCHANGE, THERMAL SENSING, AND CONDUCTIVITY SENSING

摘要

PROBLEM TO BE SOLVED: To provide a pump that imparts low shear forces and turbulence on the fluid being pumped.

SOLUTION: A reciprocating positive-displacement pump includes: a hemispherical rigid chamber wall; a flexible membrane attached to the rigid chamber wall, so that the flexible membrane and rigid chamber wall define a pumping chamber; an inlet for directing flow through the rigid chamber wall into the pumping chamber in a direction that is substantially tangential to the rigid chamber wall; and an outlet for directing flow through the rigid chamber wall out of the pumping chamber in a direction that is substantially tangential to the rigid chamber wall.
