Cast Iron Self Priming Pump

As a mature self-priming Pump, it adopts built-in gas-liquid separation self-priming structure, only needing one-time water filling during initial use, and can automatically exhaust air and form vacuum suction after repeated startup without auxiliary foot valves. The single-stage closed impeller hydraulic design stabilizes outlet flow and pressure, qualifying it as a stable suction pump with up to 9m maximum self-priming lift to absorb water from low water sources. Horizontal integrated monoblock layout saves installation space, with built-in overload, overheat and undervoltage triple protection to avoid single-phase motor burnout during unattended farm operation. Every finished pump undergoes 48-hour continuous self-priming circulation testing before factory delivery.

Applicable for farmland small-area irrigation, village well water lifting to water towers, villa courtyard tap water pressurization, livestock breeding clean water supply, garden landscape fountain water delivery, and construction site temporary clean water pipeline boosting.

1.Thick anti-rust cast iron integral cavity creates a durable self priming pump with stable outdoor self-priming capacity.
2. Built-in gas-liquid separation structure eliminates repeated manual water filling, forming a labor-saving 220V single phase Pump for scattered low water sources.
3. Polished single-stage hydraulic channel ensures steady water output as a qualified single stage suction pump, completely solving priming trouble and power access limitations of traditional centrifugal pumps for farm irrigation and village domestic water use.
