Self Priming Centrifugal Pumps

Industrial self-priming centrifugal pumps engineered with advanced priming pot systems for automatic air evacuation and superior suction lift capabilities. Our ANSI/ASME B73.1 compliant pumps eliminate manual priming needs, featuring both metallic and non-metallic construction options for handling corrosive chemicals up to 1200 m³/hr flow capacity. Ideal for applications requiring reliable restart after shutdown and suction lift operations.

Frequently Asked Questions

What is a self-priming centrifugal pump used for?

Self-priming centrifugal pumps are used for applications requiring automatic air evacuation and suction lift capabilities without manual priming. Common applications include chemical processing, water treatment, emptying tanks below ground level, intermittent operations where the pump may run dry, and systems requiring reliable restart after shutdown. They're ideal for handling corrosive chemicals, wastewater, and industrial fluids where conventional centrifugal pumps would require manual priming.

Why are centrifugal pumps not self-priming?

Standard centrifugal pumps are not self-priming because they cannot create sufficient vacuum to lift water from below the pump level when air is present in the suction line. The impeller design creates centrifugal force but lacks the ability to effectively separate air from liquid. Self-priming pumps overcome this limitation through special priming pot systems and modified volute designs that maintain liquid reserves and enable air separation, allowing automatic priming.

What pumps are self-priming?

Several pump types are inherently self-priming including positive displacement pumps (diaphragm, gear, and piston pumps), jet pumps, and specially designed centrifugal pumps with priming pot systems. Chemitek offers both metallic and non-metallic self-priming centrifugal pumps featuring advanced priming pot technology, PolyPrime systems for fluoropolymer construction, and investment-cast designs for reliable automatic priming capabilities in industrial applications.

Which is better, centrifugal or self-priming pump?

The choice depends on application requirements. Standard centrifugal pumps offer higher efficiency, lower cost, and simpler maintenance for applications where the pump remains flooded. Self-priming pumps are better for suction lift applications, intermittent operations, systems that may run dry, and installations where manual priming is impractical. Self-priming pumps provide operational convenience and reliability but at slightly higher initial cost and marginally reduced efficiency compared to standard centrifugal pumps.

How does the priming pot system work in self-priming centrifugal pumps?

The priming pot system maintains a liquid reserve in the pump casing that mixes with incoming air-liquid mixture. The impeller creates turbulent mixing that separates air from liquid, with air being discharged through the volute while liquid recirculates. This process continues until all air is evacuated and normal pumping action begins. Chemitek's priming pot systems feature optimized designs for quick priming and reliable operation across various chemical applications.

What maintenance is required for self-priming centrifugal pumps?

Maintenance includes regular inspection of the priming pot liquid level, mechanical seal condition, impeller clearances, and suction line integrity. The priming chamber should be checked for debris accumulation, and foot valves (if used) require periodic inspection. Chemitek provides comprehensive maintenance guidelines, spare parts availability, and AMC services to ensure optimal performance and extended operational life of self-priming systems.
