The mechanical design of the screw pump relies on the precise clearance between the screws, making it unsuitable for solid or abrasive fluids. Individual manufacturers will confirm the level of filtration required for screw pump protection.

The three-axis screw pump is a development of the ancient Archimedes screw principle. The design is a rotary positive displacement design, and all of these pumps create a partial vacuum by opening and closing or sweeping away a series of voids or volumes.

The three-screw pump achieves this by having a central drive screw that engages with two separate idler screws. In some ways, the design can be compared to a helical gear pump, where the teeth have been pulled out axially to form a true helical screw. Because the meshing screws are relatively long, the efficiency is very high, and the same "slip" problem as the gear pump does not occur.

In addition, the design really balances the small aspect ratio, making it suitable for high-speed operation. Finally, the design cleverly eliminates all radial loads, making the pump very simple and reliable.

The above content explains whether the screw pump can handle solids. In addition, Shenzhen Oudejie Technology specializes in selling imported Knoll screw pumps, and promises to sell products that are new and imported, and provide quotation, selection, product information and other services for our customers.
