Hose pumps are a type of positive displacement pump that use a flexible hose to move fluids. They work by compressing the hose, which creates a vacuum that draws in the liquid. As the hose returns to its original shape, the liquid is pushed out, making them effective for transferring various types of fluids, including slurries and viscous materials. These pumps are known for their ability to handle abrasive and corrosive substances without damaging the pump itself. They are commonly used in industries such as mining, food processing, and chemical manufacturing, where reliable fluid transfer is essential.
