Self Priming Pump
Cart(0)
Description
A self-priming pump is a type of centrifugal pump designed to remove air from the pump and piping system, allowing it to start without needing manual priming. These pumps are commonly used for applications where the pump must handle a mixture of air and liquid. The pump is equipped with a built-in priming chamber or mechanism that facilitates the removal of air, making it suitable for environments where there may be intermittent air pockets or air trapped in the system.
Key Features
- Automatic Priming: No manual intervention required after the initial prime.
- Air and Liquid Handling: Capable of handling a mix of liquids and gases, making it suitable for air-entrained applications.
- Dry Running Protection: Some models include dry running protection to prevent damage if the pump runs without liquid.
- Maintenance-Friendly: Designed for easy disassembly and reassembly, reducing downtime for maintenance.
Applications
- Water Supply and Drainage: Used in dewatering, flood control, and sewage handling.
- Irrigation: Effective in agricultural irrigation systems.
- Industrial Use: Suitable for cooling water circulation, chemical handling, and general industrial fluid transfer.
- Marine Applications: Employed in bilge pumping and ballast transfer systems.
- HVAC Systems: Used in heating and cooling systems for water circulation.
- Construction Sites: For handling slurry, mud, and water in construction and excavation works.
