40/410 40mm Plastic Shampoo Brush Foaming Pump for Facial Cleanser Washing Dispenser Pump
A 40mm foaming pump is a dispensing closure designed to mix liquid soap or cleanser with air, producing a rich foam directly from the bottle. The "40mm" refers to the neck size of the bottle it fits—this is a standard size commonly used for foaming soap dispensers in both residential and commercial settings .
Here is a detailed breakdown of the types, technical specifications, applications, and sourcing information for 40mm foaming pumps.
Types of 40mm Foaming Pumps
There are a few key variations to consider, each with different internal designs:
| Type | Description | Key Feature | Best For |
|---|---|---|---|
| All-Plastic (Plastic Spring) | Uses a plastic spring instead of metal | Fully recyclable, eco-friendly | Green / sustainable brands |
| External Spring (Metal) | Metal spring is visible outside the liquid path | Durability, standard industry design | General hand soap, dish soap |
| Internal Spring (Metal) | Metal spring is sealed inside the mechanism | Non-spill, cleaner appearance | Premium products, travel use |

How to Choose the Right 40mm Foaming Pump
-
Measure your bottle neck – Confirm the finish is 40/410 (or 40/400, 40/415). If uncertain, measure the inside diameter and thread pitch.
-
Match dosage to product – 0.4-0.8cc for standard hand soap; 1.2-1.5cc for thicker formulations or larger coverage.
-
Consider your formula – Ensure pump materials (spring type, gaskets) are compatible with your liquid (e.g., silicone gaskets for oily formulas) .
-
Choose locking style – Up-lock or clip-lock preferred for e-commerce and secure shipping .
-
Order dip tubes – Specify exact bottle height so tubes reach the bottom.
In short: A 40mm foaming pump—especially the common 40/410 size with 0.8cc output and up-lock mechanism—is the industry standard for foaming soap and cleanser bottles. If you are selling online, prioritize e-commerce capable models with secure locking features .
