Since the pump body adopts a multi-chamber design and is equipped with a flow-limiting component, this pump can adapt to the delivery of fluids with different viscosities and properties, and has strong versatility and adaptability. By accurately controlling the flow at the water inlet end, system instability caused by flow fluctuations, such as pressure shock, can be avoided, thereby improving the stability of the entire fluid delivery system.
