Self Priming Pumps

Our range of pumps that can be self priming includes AODD, peristaltic, vane, centrifugal, ECP, eccentric disc, progressive cavity, turbine and rotary lobe. As a result we have self priming pumps that can handle solids, satisfy hygienic requirements and withstand corrosive liquids.

Benefits of Self Priming Pumps

• Prevents dry running: Self-priming pumps are capable of re-priming themselves automatically if the fluid level in the suction line drops below the pump's impeller. This self-priming ability therefore prevents dry running, thus ensuring continuous operation even during fluctuations in fluid levels.
• Lower maintenance requirements: The absence of external priming systems or foot valves reduces the complexity of the pump's design, thus reducing the number of components that may require maintenance.
• Improved efficiency: Self-priming pumps are designed with optimal hydraulic performance, which increases overall efficiency, therefore saving energy and decreasing operating costs.
• Versatility: Self priming pumps can be utilised throughout various 

Centrifugal or Positive displacement pumps

Centrifugal self-priming pumps and positive displacement self-priming pumps tend to differ in their operating principles. Centrifugal self-priming pumps utilise a specially engineered impeller and casing to handle air or gas in the suction line, which creates a vacuum, drawing in the fluid to prime the pump without external assistance. Whereas, positive displacement self-priming pumps tend to rely on an external priming process, such as a foot valve or vacuum pump, to remove air from the suction line and fill the pump chamber with the fluid before they can effectively operate.
