As the name suggests, a self-priming pump is a type of pump that does not require water injection before starting. After a short period of operation, it relies on the pump's own function to suck up water and put it into normal operation. The CQZ self-priming magnetic pump not only has self-priming function, but also has a magnetic drive structure with fully sealed, corrosion-resistant, and leak free characteristics. It is an ideal pump for automated remote control and flow use.
