1. A method for heating or cooling a fluid, the method comprising:

  • providing at least one reciprocating positive-displacement pump, each pump having;

    a curved 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 fluid through the rigid chamber wall into the pumping chamber in at least one of (a) a direction that is substantially tangential to the rigid chamber wall and (b) a direction that provides low-shear flow into the pumping chamber; and

    an outlet for directing fluid through the rigid chamber wall out of the pumping chamber in at least one of (a) a direction that is substantially tangential to the rigid chamber wall and (b) a direction that provides low-shear flow out of the pumping chamber;

    providing a heat exchanger; and

    pumping the fluid from at least one source using the at least one reciprocating positive-displacement pump so as to cause the fluid to pass through the heat exchanger.
