Publication number: 20190054398Abstract: A precision pump system having a motor driver for accurately and repeatedly delivering process fluid, (e.g., photo chemicals) using a pumping fluid with minimal process fluid loss to a fabrication process and whereby the motor driver can be easily and quickly replaced without interrupting the fluid flow path. This is accomplished with the use of a gas removal reservoir having at least one vertical partition therein and at least one free end near a top side of the gas removal reservoir where both the input and output to the gas removal reservoir are located on a bottom surface and a pumping fluid reservoir that are associated with the pump, either integrated with the pump or closely adjacent. In addition, this precision pump system can be remotely monitored, viewed and controlled over the Internet. In addition, trapped process fluid within a downstream filtering block can be recirculated to the gas removal reservoir when trapped gas in the filter is removed.Type: ApplicationFiled: September 27, 2018Publication date: February 21, 2019Inventors: John C.

Publication number: 20150322938Abstract: A pump for one or more different process fluids is provided including a pumping chamber having a process fluid inlet and outlet coupled to a process fluid valve on each pumping chamber for selectively preventing and allowing flow of process fluid through the pumping chamber. An actuation mechanism for pumping actuating fluid to actuating fluid chambers is provided that is in communication with the actuating fluid chambers to permit flow into each actuating fluid chamber of incompressible actuating fluid. A diaphragm separates each pumping chamber from an associated actuating fluid chamber for separating process fluid from actuating fluid. The actuation mechanism is removable by a quick disconnect that provides for disconnection of the activation mechanism without affecting process fluid. Operation of the actuation mechanism to displace actuating fluid causes actuating fluid to flow only into each actuating fluid chamber having an opened process fluid valve, resulting in pumping.Type: ApplicationFiled: July 17, 2015Publication date: November 12, 2015Inventors: John Laessle, John Vines, Brian Kidd

Patent number: 8441222Abstract: A system for measuring current in an H-Bridge motor drive circuit and using that current to determine the output of a device powered by the motor. A particular embodiment is disclosed for a motor-driven fluid pump. Motor current is measured at predetermined pump pressures and flow rates to create calibration tables relating motor current to pump pressure. Once calibrated, the system determines pump pressure based on motor current by referring to the calibration tables. In an embodiment, the pump is driven to achieve a predetermined fluid dispense profile. The system monitors pump pressure by measuring motor current and determines if the dispense profile is being achieved and sets alarms if predetermined thresholds are not maintained. The system also detects pump wear based on the current measurements and issues warnings to the user in such conditions.Type: GrantFiled: July 14, 2010Date of Patent: May 14, 2013Assignee: Integrated Designs, L.P.Inventors: Donovan Keith Manzarek, John Laessle, John Charles Vines
