CWX marine horizontal self priming centrifugal vortex pump

CWX horizontal self priming centrifugal vortex pump is applicable to transport seawater and fresh water for drinks, washing and sanitary with the temperature no higher than 85 degree C.

When the impeller of CWX Marine self-priming vortex pump rotates, centrifugal force is generated. Under the action of this centrifugal force, the liquid flows into the blade root from the side face of the pump shell and is thrown outward to the groove of the cover plate on both sides. This part of liquid originally moves in a circle with the blade and has a certain velocity energy. In the groove of the cover plate, velocity energy changes into pressure energy. And then it's grabbed by the leaf. In the process of the liquid particle from the inlet to the outlet, such action is repeated many times, and the energy increases successively, just like the liquid in the centrifugal pump by the multi-stage impeller action. Liquid in the channel along with the star impeller movement, to the cut-off point, because the channel is suddenly blocked, liquid from the outlet hole out. The exit hole is set on the exit cover plate, and the entrance hole is set on the entrance cover plate, which is opened in the place where the groove suddenly appears behind the cut-off area, where the negative pressure is obviously to absorb the liquid.

CWX Marine self-priming vortex pump performance characteristics

(1) the characteristics of small volume and light weight of vortex pump have great advantages in Marine installations.

(2) having self-priming ability or realizing self-priming by means of simple devices.

(3) the head characteristic curve has a steep drop, so it is not sensitive to the pressure fluctuation in the system.

(4) some vortex pumps can realize the mixture of vapor and liquid. This is of great significance for pumping volatile liquid containing gas and high temperature liquid with high vaporization pressure.

(5) vortex pump structure is simple, casting and processing technology are easy to achieve, some vortex pump parts can also use non-metallic materials, such as plastic, nylon molded impeller.
