Claims

[Scope of utility model registration request]

A head cover that has a suction channel communicating with the suction port of the pump casing, an air/water separation chamber, and a discharge channel communicating with the discharge port of the pump casing via the air/water separation chamber is attached to the top of the pump casing. In the self-priming pump, the head cover is formed into two parts, an upper head cover and a lower head cover, and a float guide for accommodating a float of a float switch is detachably attached to an inlet portion of the upper head cover to the discharge flow path. A self-priming pump that is characterized by the fact that it can be installed freely.
