You have undoubtedly observed the wide range of uses of Stainless Steel Submersible Pump. Although the pump series uses centrifugal force to pump water, there are many ways to apply this force. One of the main differences in the design of various centrifugal pumps is the type of impeller used. The blades of the impeller flow from the center to the outer edge of the circle. When the impeller rotates, it sucks liquid into the center or eyes of the impeller, and the rotating blades generate centrifugal force, which pushes the liquid to the outside of the pump casing and finally discharges it from the discharge port.
The blades of the enclosed impeller are "sandwiched" between two solid circular plates. The liquid flows through the channels between the impellers and between the plates. This design creates the most efficient flow from the eye hole to the discharge port. Although this is the most common impeller type, a centrifugal pump of this design is suitable for clear liquids.
Half-open impeller The blades of the semi-open impeller are fixed on a plate, and the other side of the impeller is exposed inside the pump casing. This design is less efficient than a closed impeller because the liquid immediately interacts with the rest of the liquid in the pump casing. However, this design can also better absorb suspended particles in the liquid and can handle more viscous fluids.
Centrifugal pumps with open impellers in the design of open impellers are, as the name suggests, with blades open on both sides. Since the blades are not supported on either side, they tend to be weaker. Although they can handle suspended solids, these pumps are smaller and less powerful in order to reduce the frequency of braking the blades. In addition, due to the open design, the liquid flowing into the pump interacts with the liquid already in the casing, resulting in the lowest efficiency of this centrifugal pump.
The type of impeller used in Stainless Steel Submersible Sewage Pump will depend on the intended use of the pump. In most cases, the application requires the most efficient flow of liquid, which is a job for closed impellers. These are the strongest designs, allowing them to transport more water faster.
