Self-priming pumps are designed to overcome or generate pressure in the discharge branch. However, significant differences exist in the suction side among these pumps. Some require flooded suction to function, while others can draw liquids from considerable depths.
The ability to self-prime is a crucial feature that simplifies installation challenges. These pumps can be positioned above the free surface level of the storage tank they draw from, offering advantages in various technical scenarios, such as draining IBC containers from the top or overcoming pipeline siphons, and more.
How Self-Priming Pumps Work
- The suction chamber is filled through the suction port when the pump is turned on.
- During suction, air mixed with the liquid in the suction pipe creates a vacuum in the internal spiral. Upon separation, the air ascends through the discharge pipe, and the liquid returns to the suction chamber.
- This circulation continues until the liquid replaces all the air in the suction pipe, initiating the pumping process.
- When the pump is turned off, the suction chamber with the goose neck ensures an adequate amount of liquid for efficient re-priming.
AxFlow Offers Exceptional Self-Priming Pumps
We provide a diverse range of self-priming pumps in various construction types and materials. Each pump type offers specific self-priming capabilities. Hoses and peristaltic pumps demonstrate exceptional self-priming abilities, reaching suction lifts of up to 9.5m. Spindle pumps and many air diaphragm or piston diaphragm pumps also exhibit excellent suction properties. In the realm of centrifugal pumps, self-priming variants are categorized into specialized series. Self-priming centrifugal pumps always combine centrifugal pumping with the principles of fluid circulatory.
