External Spring Liquid Pump

An external spring liquid pump is a dispensing device driven by an external spring mechanism. It is mainly used to accurately dispense liquids, lotions, pastes, and other products from packaging containers. Unlike traditional lotion pumps and compression pumps, the external spring liquid pump adopts an innovative solution of external spring in structural design, which can not only effectively reduce the internal space occupied by the pump body, but also improve the durability and cleanability of the pump, reduce the risk of liquid accumulation in the pump head, and ensure the efficient operation of the pump. The external spring liquid pump can adjust the amount of liquid dispensed each time it is pressed according to user needs. By adjusting the adjustment ring or rotating device on the pump body, users can flexibly adjust the dispensing amount according to the viscosity and usage requirements of different liquids, reduce waste, and improve the user experience.
