    Abstract: A pump for ultra-pure fluids comprises a flexible diaphragm separating a fluid chamber from an air chamber. The diaphragm creates an airtight seal between the fluid chamber and the air chamber when a self-centering and trapezoidal shaped wedge compressively forces the diaphragm into a trapezoidal shaped perimeter cavity surrounding the chambers. Any leak from the fluid chamber into the air chamber is detected by a fiber optic system comprising two optical fibers that are disposed at an angle that is calculated to enable light to pass between the fibers only in the presence of a liquid having a predetermined index of refraction. The fiber optic system can also be used to determine the stroke of the pump by disposing the fiber optic lines at an angle calculated to reflect light off of the oscillating diaphragm when the diaphragm arrives at a predetermined location.

    Abstract: A pump for ultra-pure fluids comprises a flexible diaphragm separating a fluid chamber from an air chamber. The diaphragm creates an airtight seal between the fluid chamber and the air chamber. Any leak from the fluid chamber into the air chamber is detected by a fiber optic system comprising an element and two optical fibers that are disposed such that light is detected by the second optical fiber only when the element is not in contact with liquid. A second fiber optic system can also be used to determine the stroke of an oscillating member by disposing the fiber optic lines at an angle calculated to reflect light off of the oscillating member when the member arrives at a predetermined location. The fiber optics are adapted to be resistant to corrosion, non-igniting, and non-contaminating.

    Abstract: A pump for ultra-pure fluids, such as hot, de-ionized water, processing acids, and the like, such as those used in the semiconductor processing industries, is designed to operate at greater than 10 and often 30 or 50 million cycles without failure, and to be failclean. A diaphragm pump maintains a free diaphragm, supported in a contoured chamber for driving and being driven by a piston, able to move radially, rather than absorbing misalignment or distortions. A self-energizing, self-centering, trapezoidal seal captures a constant-thickness diaphragm between a head and body forming the chamber of the pump, separating a body portion and a head portion. An oriented, calendered, multi-layered chlorofluorocarbon diaphragm may be the same material chemically as the body, head, or both. Non-reactive pilots control an operating (motive) fluid, detecting the end-of-stroke whether near the head or near the body. An integrated base controller for the operating fluid supports the apparatus, has a quick exhaust for dumping external-controller air overboard after use, and a bias disk to provide precise, digital, spool positioning within an operational range of pressure differentials. The heads may connect to the body by slip rings, so heads remain registered. Cantilevered portions of the head may absorb secondary creep and provide continued spring loading using exclusively non-reactive materials, no metals, and no elastomers, as a failclean system.

    Abstract: A membrane pump usage condition detection system and a method of determining a membrane pump usage condition. The membrane pump usage condition detection system comprises a membrane pump defining a flow path arranged to be opened and closed by at least one valve, a measuring device; a comparator; and a signal generator. The measuring device is configured to determine an electrical characteristic between two points on the flow path of the membrane pump, one point arranged upstream of the at least one valve and the other point arranged downstream of the at least one valve. The measuring device measures the electrical characteristic when the at least one valve is closed. The comparator is configured to monitor the electrical characteristic. The signal generator is arranged to provide an output signal when the electrical characteristic is indicative of a membrane pump usage condition.
