Introduction to Self – Priming Pumps
Self – priming pumps are a type of pump that can evacuate air from the suction line and start pumping liquid without the need for external priming. They are widely used in various industries such as agriculture, water treatment, chemical processing, and construction. These pumps are designed to handle different types of fluids, including clean water, wastewater, and corrosive liquids. Their self – priming ability makes them convenient and efficient, reducing the time and effort required for pump startup. Self-Priming Pumps
