Abstract: A process fluid pump can include a pump chamber, an inlet valve, and an outlet valve. Diaphragm regions can define at least a portion of each of the pump chamber, the inlet valve, and the outlet valve. The diaphragm regions can each have an actuation region with a surface that is convexly shaped when the formed actuation region is in a natural unstressed first state, and each formed actuation region can be actuated by a motive fluid to transition to a second state in which the surface is non-convexly shaped.
Abstract: In some arrangements, a pump for moving a fluid has one or more pump chambers and one or more flow control valves with diaphragm actuation regions. Motive fluid can activate the diaphragm actuation regions, and a pattern of fluid flow can be controlled by varying the pressure levels of the motive fluid.

Abstract: A pump for transferring a process fluid has a first pump chamber and a second pump chamber. A motive fluid actuates the pump chambers and control flow valves. The direction of process fluid flow is controlled by varying the amounts of pressure or the use of a vacuum. The control flow valves utilize diaphragms for actuation.

Abstract: A heat exchanger apparatus enables the temperature of a liquid located external to the apparatus in a recirculation loop to be controlled by heat transfer within the apparatus. A manifold fitting is also provided for distributing fluid from multiple conduits to a single conduit.
