    Self priming centrifugal pump installation


    Self-priming pump is a special type of centrifugal pump that has the ability to self-prime and operate normally without the need for liquid filling. Self-priming pumps are widely used in industrial drainage, water supply to high-rise buildings, garden irrigation, boosting fire protection systems, and circulating HVAC refrigeration.

    Self priming pump applications

    Tips: Are there any limitations to using self-priming pumps?

    • Limited suction lift: While self-priming pumps are designed to handle suction lift, there is a practical limit to the height they can lift water. The specific limit depends on the design and capacity of the pump, but typically, it ranges from 15 to 25 feet (4.5 to 7.6 meters). If the suction lift required exceeds this limit, a different type of pump or additional measures like installing a foot valve may be necessary.
    • Priming time: Self-priming pumps require some time to evacuate air from the suction line and fill it with water before they can begin pumping efficiently. The priming time can vary depending on factors such as the size and length of the suction line, the volume of air in the system, and the pump's capacity. It's important to consider this priming time when determining the overall pumping efficiency and response time for a particular application.
    • Initial priming: Self-priming pumps typically require an initial priming before they can operate effectively. This means that during the installation or after maintenance, the pump needs to be manually primed to fill the suction line and pump casing with water. Although this is a one-time requirement, it adds an extra step during the setup process.
    • Maintenance and wear: Self-priming pumps have additional components, such as an impeller with a priming chamber or a separate priming system, which can be more complex than standard pumps. These additional components may require regular maintenance and can be subject to wear and tear, potentially affecting the pump's performance and reliability.
    • Efficiency and performance: Self-priming pumps may have slightly lower efficiency compared to non-self-priming pumps due to the design compromises necessary to enable self-priming capability. Additionally, their performance may be affected by factors such as the presence of debris or air in the pumped fluid, which can reduce their efficiency or cause cavitation.

    Great pump
    So far so good. It ran really well. I use it to water the gardens with rain catch water. It built up pressure really good. Niceeee
