    摘要： A fluid conditioning module having a fluid inlet and a fluid outlet is provided. The fluid conditioning module includes a first pump element, a second pump element, a pressure regulator, a controller, and a prime mover to impart rotational motion in the first and second pump elements. A first pump inlet is in fluid communication with the fluid inlet. A filter inlet is in fluid communication with a first pump outlet and a second pump outlet, and a filter outlet is in fluid communication with the fluid outlet. A pressure regulator inlet and a pressure regulator outlet are in fluid communication with the filter outlet and a recirculation conduit, respectively. The control valve has a first position and a second position, which allows fluid flow through the recirculation conduit. The controller adjusts operation of one or more of the prime mover and the control valve based upon a predetermined parameter.

    摘要： A differentially pumped vacuum system includes first, second and third chambers, and a pumping arrangement for evacuating the chambers. The pumping arrangement includes a compound pump having a first inlet connected to an outlet from the first chamber, a second inlet connected to an outlet from the second chamber, a first pumping section and a second pumping section downstream from the first pumping section, the sections being arranged such that fluid entering the compound pump from the first inlet passes through the first and second pumping sections and fluid entering the compound pump from the second inlet passes through, of said sections, only the second section. The pumping arrangement further includes a booster pump connected to an outlet from the third chamber, and a backing pump connected to the exhaust from the booster pump. Fluid exhaust from the compound pump can be conveyed to either the booster pump or the backing pump as required.

    摘要： A pump assembly for circulating water in an evaporative cooler is provided. The pump assembly may include a housing which defines a cavity. The pump assembly may also include an impeller received in the cavity of the housing. Further, the pump assembly may include a rod which may be operatively associated with the impeller and extends out of the housing. Moreover, the pump assembly may include a connecting member which is operatively associated with the rod, and may be adapted to be operatively associated with a shaft of a fan assembly incorporated into the evaporative cooler. The connecting member may be adapted to transmit rotary motion of the shaft to the impeller, thereby enabling the pump assembly to circulate water in the evaporative cooler.
