Abstract: The present disclosure relates to a flow turning system for imparting a rotational, swirling motion to a fluid flowing through the flow turning system. The system may comprise a housing and a flow turning element supported within the housing. The flow turning element may have a plurality of circumferentially spaced vanes projecting into a flow path of the fluid as the fluid flows through the flow turning system. The vanes impart a swirling, circumferential flow to the fluid to help prevent contaminants in the fluid from adhering to downstream components in communication with the flow turning system.

Abstract: The present disclosure relates to a pneumatically driven pump for pumping a fluid. The pump may have a pump housing configured to receive a pressurized fluid signal. An inlet screen may be included at an end of the pump housing for admitting fluid therethrough into an interior area of the pump housing. An inlet casting may be included which is disposed within the pump housing adjacent the inlet screen. A poppet valve may be included which is configured to seat against the inlet casting. The poppet valve may have a propeller structure for creating a fluid pulse when the poppet valve seats, which helps to dislodge particles that have collected on the inlet screen, and thus help to maintain the inlet screen in a clean condition.
