22/410 PP Serum/Treatment Pump, 0.48cc Dosage, Twist Lock

What this packaging is

An external metal spring — positioned completely outside the pump body with zero liquid contact — makes this PP serum pump a smart call for sensitive, active-rich formulations. The 22/410 PP Serum/Treatment Pump delivers a precise 0.48cc dose per stroke with a twist-lock mechanism that prevents accidental dispensing during shipping and travel. Built from polypropylene with a PE gasket and dip tube, the 22mm neck and 410 finish fits a wide range of bottle formats. A glossy collar finish and decoration options including electroplating, spray coating, and water transfer printing give face serum and moisturizer brands real flexibility at shelf.

Why brands choose this

• Formula-safe external spring architecture: The metal spring sits entirely outside the pump body, eliminating liquid-to-metal contact — a meaningful advantage for brands formulating with acids, peptides, or other reactive actives where contamination risk or ingredient degradation is a real concern.
• Precision dose plus travel-ready twist lock: A consistent 0.48cc output per stroke removes guesswork for consumers and reduces product waste, while the twist-lock closure prevents leakage or accidental dispensing — a combination that fits cleanly into the growing demand for travel-friendly, no-mess skincare packaging.
• Decoration versatility for brand differentiation: Electroplating, spray coating, and water transfer printing options — plus custom color availability — mean this pump can be finished to match premium, minimalist, or bold brand aesthetics without requiring a custom-tooled component, keeping development timelines tight at a four-week production lead time.
