Abstract: A filtering system for filtering particles from a flow of fluid is disclosed, and includes a filter device for removably positioning in a lumen of a pipe carrying the flow of fluid. The filter device has an upstream side for positioning in an upstream direction of fluid flow and a downstream side for positioning in a downstream direction of fluid flow. The filter device comprises a perimeter rim extending along the perimeter edge of the filter device and defining an opening, and a plurality of filter bars extending across the opening to form a plurality of slots therebetween. Each of the filter bars of the plurality of filter bars has a transverse cross sectional shape. The transverse cross sectional shape has a transverse width toward the upstream side of the filter device that is relatively wider than the transverse width toward the downstream side of the filter device.

Abstract: A pump testing apparatus is disclosed for testing output characteristics of a fluid flow exiting a pump. The apparatus includes a flow testing structure for testing characteristics of the fluid flow, a first chamber having an interior for receiving a fluid flow exiting the flow testing structure, and a second chamber having an interior for receiving fluid flow from the first chamber. The second chamber has an entrance opening for receiving fluid flow into the interior of the second chamber and a discharge opening for discharging fluid flow from the interior of the second chamber, the second chamber defining a convoluted path for the fluid flow between the entrance opening and the discharge opening. The apparatus also includes structures located in at least one of the first chamber and the second chamber for reducing a velocity of the fluid flow.
