Beschreibung
Zusammenfassung:	Apparatus, e.g., including a pump or rotary device, having a discharge casing and a discharge casing insert. The discharge casing may be configured with a discharge flow pathway for providing a flow of effluent being pumped and discharged, the discharge flow pathway having a discharge flow pathway wall, the discharge casing also configured with a discharge casing insert borehole that passes from an outer surface of the discharge casing through the discharge flow pathway wall. The discharge casing insert may include a discharge casing Venturi plug portion to be received in the discharge casing insert borehole and arranged in the discharge flow pathway, the discharge casing Venturi plug portion configured with a restricted discharge flow pathway for providing a partial obstruction in the discharge flow pathway and the flow of the effluent being pumped and discharged.
