CLC 28-410 Ribbed PP Lotion Pump with Round Flat Head, 2cc Dosage with External Spring Design

What this packaging is

An external spring design sets this pump apart — the stainless steel spring sits in a dry chamber completely outside the liquid flow path, eliminating corrosion risk and formula contamination in one move. The 28-410 Ribbed PP Lotion Pump with Round Flat Head delivers a consistent 2cc dose per actuation and fits any 28mm 410-neck bottle, making it a straightforward drop-in for existing packaging lines. A plastic ball valve rated for acid and alkali resistance broadens compatibility across rinse-off and leave-on formulations alike. Built for hair treatments, shampoos, conditioners, body lotions, and hand soaps, this pump brings engineering integrity to high-volume personal care and bath lines.

Why brands choose this

• Formula-safe engineering for reactive and active formulations: The external spring sits in a sealed dry chamber with zero contact with your formula — no corrosion, no contamination. That's a real advantage for brands working with acidic, alkali-heavy, or protein-rich hair and body care formulations where pump degradation is a known failure point.
• Acid- and alkali-resistant ball valve expands compatibility: The plastic ball valve is specifically rated to hold up against chemically aggressive formulas, giving formulators and product developers more flexibility without having to audit pump compatibility every time the formula changes — a quiet but meaningful time-saver during development.
• Consistent 2cc dosage supports dose-controlled positioning: A fixed 2cc actuation makes it easy to communicate per-use value on pack and in marketing, and it fits naturally into the consumer ritual for shampoos, conditioners, and body lotions where dispensing consistency directly affects satisfaction and product efficiency claims.
