Self-priming Pump Series
Self-priming Pump Series
A self-priming pump is a type of pumping equipment that can store a certain amount of liquid within its pump chamber and, through the vacuum effect generated during startup, draw liquid from a lower level and deliver it to a higher level. Its key advantage lies in its ability to automatically vent air and draw liquid without the need for priming—a feature that makes it simple to operate and suitable for a wide range of working conditions.

Key Points for Selection, Installation, and Maintenance of DC Submersible Pumps
Selection criteria: Choose a pump with a rated head equal to the actual required head plus pipeline losses (10%–15%). Match the flow rate to the water demand. If the liquid contains particles or is corrosive, select materials that are wear-resistant and corrosion-proof (e.g., 316 stainless steel or engineering plastics). In solar-powered applications, prioritize BLDC motors paired with MPPT controllers.
