Abstract: A dry material transfer pump comprises an outer tube including an outer tube channel having an upstream end that is axially aligned with a downstream end thereof, and a plenum portion having a cross-sectional width that is larger than a cross-sectional width of the outer tube channel. A pressurized gas inlet is defined through the outer tube and is in fluid communication with the plenum portion. An inner tube is disposed annularly within the outer tube channel and defines an inner tube channel configured to receive particulate matter. At least one opening is defined radially through a wall of the inner tube and fluidly couples the plenum portion to the inner tube channel to allow the pressurized gas to flow from the plenum portion into the inner tube channel and create suction within the inner tube channel for drawing the particulate matter through the inner tube channel.

Abstract: Embodiments described herein relate generally to filter assemblies that include filter elements with cross-channel flow having flat and/or folded arrangements for optimized functionality and performance. The filter assemblies may be formed (e.g., shaped, constructed, etc.) using a variety of shapes, angles, configurations, and materials to improve the filtration and cross-channel flow of fluid through the filter media. The filter media may implement a wide variety of patterns (e.g., repeating, origami, rounded, etc.), shapes (e.g., tetrahedral, rhombus, square), and construction (e.g., pleated, integrated, interdigitated, etc.).
