The invention discloses a gland applied to a centrifugal pump. The gland comprises a gland body, a sealing element and a collecting part. The sealing element is arranged on the outer surface of the gland body, and the collecting part is provided with a containing space. The collecting part is fixedly connected to the lower end of the gland body, and the front end of the gland body is fixedly connected with the rear end of the centrifugal pump, so that leakage media leaking when the centrifugal pump runs enter the containing space through the gland body. By means of the gland applied to the centrifugal pump, collection and discharge of the leakage media are achieved when the centrifugal pump runs so that the centrifugal pump can save filler cost, and production cost is further reduced.
