Excellent choice! A 4cc lotion pump is a specific and very common size in the world of packaging. "4cc" refers to the dosage volume—it dispenses approximately 4 milliliters (ml) of product per full pump stroke.
Dose Volume: ~4.0 ml per pump. This is considered a medium-to-large dose, ideal for products where a substantial amount is needed per application.
Typical Viscosity: Designed for medium-viscosity products like lotions, creams, shower gels, thicker serums, and some liquid soaps. It has wider flow paths than a 1cc or 2cc pump to handle thicker formulas.
Neck Finish: The most common bottle neck finish for a 4cc pump is 28-410. This means:
28mm is the outer diameter of the bottle's neck thread.
410 refers to the specific thread profile and cap/pump skirt design.
Construction: Standard components: PP/PE plastic body, stainless steel spring, and a rubber or PE gasket for sealing.
