Professional Matt Lotion Pump Manufacturer
405 Lotion Pump — 4.5 ml, Outer Spring

Overview

FAQ

Frequently asked questions

Which neck sizes does this pump fit?
Our lotion pumps cover 24/400, 24/410, 28/410, 33/410 and 33/415. Send us your bottle neck drawing and we will confirm the matching closure before sampling.
Can the dosage be adjusted for our formula?
Yes. Standard series run from 1.0 ml to 4.5 ml per stroke, and a custom dosage can be developed for a specific viscosity. Tell us your target output and we will match it at sampling.
Outer spring or inner spring — which should I choose?
An outer spring keeps metal away from the formula and suits aggressive or high-pH products such as cleaning liquids. An inner spring gives a cleaner look for cosmetics.
How is leak-proofing tested?
Every pump uses a multi-layer leak-prevention design and is vacuum-tested before packing, with gasket compression verified under cold-transit and high-temperature conditions.
What is your MOQ?
Our standard MOQ is 10,000 pcs per model and closure finish. Tell us your project and our sales team will confirm the arrangement for your order.
