18-tooth Lotion Pump Head

This vacuum pump head is designed specifically for mid‑to‑high‑end emulsions, serums, sunscreens, and foundations, serving as the complete dispensing interface for airless packaging. In terms of sealing performance, the pump head utilizes a precision‑fit between the sealing lip and the inner wall of the pump chamber, combined with a double‑layer piston seal, effectively preventing leakage caused by transportation bumps and daily inversion. It also ensures smooth pressing, rapid rebound, and a non‑sticky feel. Regarding materials, all 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. The vacuum‑sealed structure effectively isolates air, prevents oxidation and contamination, and the built‑in rising piston at the bottom minimizes product residue. Choosing this vacuum pump head guarantees smooth and reliable dispensing with every press, while preserving the purity and freshness of your formula.
