Self priming pump automatically evacuates air from the suction line and draws liquid without manual priming. It floods its internal casing and uses impeller rotation to form vacuum and lift fluid from below the pump. It works reliably for water, wastewater, fuels, or slurry even when the pump sits above fluid level. It suits industrial, construction, dewatering and wastewater transfer applications needing fast, repeatable liquid handling. Self priming pump reduces setup complexity and improves operational flexibility across diverse fluid-handling systems.
