| 20120224984 | DIAPHRAGM PUMP AND PUMPING SYSTEMS - 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. | 09-06-2012 |
| 20090137940 | DIAPHRAGM PUMP AND RELATED SYSTEMS AND METHODS - 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. | 05-28-2009 |
