摘要： The purpose of the present invention is to provide a small, light coolant-pump device equipped with a filter, said coolant-pump device not requiring regular maintenance. The present invention is provided with: a positive-displacement pump (9); a cyclone filter (12) provided on the intake side of the positive-displacement pump; and a non-positive-displacement pump (40) provided on the intake side of the cyclone filter (12). The cyclone filter (12) contains a primary cyclone (20) and a secondary cyclone (30) each provided with a mechanism (outlet (20c and 30c)) through which separated foreign substances (cutting debris and the like) are expelled. The present invention is set such that the discharge rate of the non-positive-displacement pump (40) is higher than the discharge rate of the positive-displacement pump (9). The positive-displacement pump (9), cyclone filter (12), and non-positive-displacement pump (40) are connected in a vertical straight line.

摘要： An integrated fluid management system is provided with capability to deliver precise flow rate and fluid dosing capability over a wide range of operator set parameters. A magnetically actuated pump head is low cost, affords simple installation, and may be disposable. Multiple pump heads may be docked to a single drive module or control module to provide concurrent metering of multiple fluids and to maintain precise volume ratio of the multiple fluids to one another. The magnetic pump head may be integrated with radio frequency Identification devices (RFID) and Hall Effect Sensors to provide customized control and fail safe operation.

摘要： A system and methods for pumping a multiphase fluid using a pneumatic pump are described herein. The method includes separating a multiphase fluid into a gas stream and liquid streams, and flowing a liquid stream into a pressure vessel of a pneumatic pump until a liquid level within the pressure vessel reaches a specified high level. The method also includes compressing the gas stream to form a high-pressure gas and pressurizing the pressure vessel by the flowing high-pressure gas into the pressure vessel until a pressure level within the pressure vessel reaches a specified high level. The method further includes pumping the liquid stream from the pressure vessel to a destination until the liquid level within the pressure vessel drops to a specified low level, wherein the high-pressure gas provides a motive force for pumping the liquid stream.

摘要： Example fluid circuits (e.g., within aircrafts) include first and second pump assemblies. The first pump assembly has an electric motor and a first fluid pump. The first fluid pump is coupled to the electric motor and has a case drain port that is in fluid communication with a case drain region of the first fluid pump. The second pump assembly is powered by hydraulic pressure from the first fluid outlet of the first fluid pump and functions to augment flow through the case drain region of the first fluid pump.
