What Are The Working Principles Of Sanitary Centrifugal Pumps?

Working principle of Sanitary Centrifugal Pump. The sanitary centrifugal pump relies on the change in the volume of the working space caused by the mutual meshing of the gears to transport liquid.

Working principle of sanitary centrifugal pump 2. The working space is composed of the pump body, pump cover and the inter-tooth grooves of the gears. The meshing gear teeth divide this space into the suction chamber and the discharge chamber. When a pair of gears rotate, the gear teeth located in the suction chamber gradually withdraw from the meshing, so that the volume of the suction chamber gradually increases, the pressure decreases, and the liquid enters the suction chamber along the suction pipe until it fills the entire inter-tooth space.

Working principle of sanitary centrifugal pump 3. As the gears rotate, the liquid entering the inter-tooth space is brought to the discharge chamber. At this time, due to the meshing of the gear teeth, the volume between the teeth is occupied, the volume of the discharge chamber becomes smaller, and the liquid is forcibly discharged. When the sanitary centrifugal pump is running, the sucked-in liquid fills the tooth grooves.

Working principle of sanitary centrifugal pump 4. As the gears rotate, the liquid is transported outward along the shell wall to the high-pressure area. Because the two gears mesh with each other, the liquid in the tooth groove at the meshing point is squeezed out and discharged into the outlet pipe. At this time, a negative pressure zone is formed in the closed space, and the liquid at the pump inlet is pressed to the pump suction port under the action of atmospheric pressure.

Working principle of sanitary centrifugal pump 5. The discharge pressure of sanitary centrifugal pump is high, the volume is small, and the flow rate is not large. In the production of paint, it is generally used to transport solvents, oils, paints and paint slurries.
