Top 10 Self-Priming Pump Suppliers in the world 2025

Introduction to Self - Priming Pump

A self - priming pump is a type of pump that can evacuate air from the suction line and start pumping liquid without the need for external priming. This feature makes it highly convenient and useful in various applications where the pump may be located above the liquid level or where the suction line may contain air. Self - priming pumps are commonly used in industries such as agriculture, water supply, sewage treatment, and chemical processing. They can handle a wide range of fluids, including clean water, dirty water, and some corrosive liquids.
