0.12cc Lotion Pump Core (Side Φ8.6)

This emulsion pump cartridge is designed specifically for mid-to-high-end emulsions, serums, sunscreens, and foundations, and is the core of the pump head’s dispensing experience. In terms of sealing performance, the pump cartridge utilizes a precise fit between the separator edge and the inner wall of the pump chamber, combined with a double-layer piston sealing structure, effectively preventing leakage caused by transportation bumps and daily inversion. It also ensures smooth pressing, rapid rebound, and a non-sticky feel. Regarding materials, the parts in contact with the product are made of PP, and the spring is made of corrosion-resistant stainless steel, with no adsorption or leaching, maintaining stable rebound even in humid environments and preventing rust contamination. In terms of compatibility, it achieves even and stable dispensing from lightweight sunscreens to fluid essences to viscous foundations, without splashing or stringing. Choosing this pump cartridge ensures smooth and reliable dispensing with every press.
