What kind of machine is a pump? A detailed explanation! Introducing the overall role of pumps!
A pump is a machine invented with the idea of conveniently obtaining water, which is absolutely essential for human life, and has gradually evolved. It has developed to be commonly used for transporting liquids from low places to high places, or from a certain location to a desired location. In other words, it mechanically works on liquids to provide them with energy in the form of position, velocity, and pressure. Pumps can be classified into two types based on their principles and structures: "non-positive displacement pumps" and "positive displacement pumps." Our company manufactures positive displacement pumps, specifically "rotary pumps" and "gear pumps." 【Overview of Pumps】 ■ A machine for transporting liquids from a certain location to a desired location ■ Provides energy in the form of position, velocity, and pressure to liquids ■ Has two important capabilities: "suction capacity" and "discharge capacity" ■ Can be classified into non-positive displacement pumps and positive displacement pumps based on principles and structures *For more details, please refer to the PDF document or feel free to contact us.
