CLC 28-410 Ribbed PP Lotion Pump with Curved Down-Lock Head, 2cc Dosage with External Spring Design

What this packaging is

An external spring design sets this lotion pump apart — the stainless steel spring sits in a dry chamber completely outside the liquid flow path, eliminating corrosion and contamination risk with reactive formulas. The 28-410 Ribbed PP Lotion Pump with Curved Down-Lock Head delivers a precise 2cc dose per stroke through a polypropylene build with an acid- and alkali-resistant plastic ball valve — making it genuinely formula-flexible. The curved down-lock head secures the pump for shipping and retail display. Compatible with heat stamping and aluminum shell finishes, it's built for hair treatments, shampoos, body lotions, and hand soaps where clean dispensing and brand-ready aesthetics both matter.

Why brands choose this

• Formula-safe external spring engineering: The spring is housed in a dry chamber with zero contact with the formula — a critical advantage for brands working with reactive, acidic, or high-actives formulations where a submerged spring would corrode or introduce contamination over time.
• Broad formula compatibility via acid- and alkali-resistant valve: The plastic ball valve is engineered to resist chemical degradation across a wide pH range, making this pump a reliable single-SKU choice for brand teams ranging across shampoos, body lotions, hand soaps, and scalp treatments without requalifying components.
• Precision 2cc dosing meets category expectations for leave-on and rinse-off care: Consistent per-stroke output keeps consumers from over-dispensing — a key retention and satisfaction driver in haircare and body care, where dose control directly affects perceived product value and how long a bottle lasts.
