The mechanical design of gear pumps relies on precision clearance, so they are not suitable for solid or abrasive media except in some very special cases. Each manufacturer will confirm the level of filtration required for gear pump protection.

Gear pump is a rotary positive displacement pump. They consist of at least two independent rotating gears that mesh with each other. When these meshing teeth are separated, they create a partial vacuum that is filled by the fluid being pumped. As the gear continues to rotate, fluid is trapped and transported around the housing to the discharge side of the pump.

Here, when the gear teeth begin to engage again, fluid is ejected, producing a pumping effect. There are many different gear pump designs, but ultimately they all use the same pumping principle. Note that contrary to popular belief, the pump does not suck! Instead, they create a partial vacuum inside them that is filled or partially filled by a fluid that must be at a higher pressure to work.

The initial fluid pressure may be atmospheric, greater than or less than atmospheric, depending on the system. In effect, fluid is pushed into the pump due to the difference in pressure between the outside and inside of the pump.

The above content explains whether the gear pump can handle solids and what the gear pump is. In addition, Shenzhen Oudejie Technology specializes in the sale of imported gear pumps, and promises to sell products are new original imports, while providing our customers with quotation, selection, product information and other services。
