Dispensing Pump Neck Size Guide


Berlin Packaging UK makes it easy for you to match a dispensing pump neck size to the correct bottle. You can use our handy sidebar when browsing through online product ranges.

However, we understand that it can be difficult to compare shapes, sizes and designs all in one location. To help you analyse the range of different dispensing pump neck sizes on offer, we have put this handy guide together so you can see all the neck sizes and designs in one location.

Neck Size Calculations

A good question we get asked by many people new to the packaging industry is:

What is meant by –

  • 28/400
  • 28/410
  • 20/410
  • 24/410?

If we take the top variable (28/400) 28 would be the width, and the 400 is the height. You can use these measurements to pick the correct bottle, so both products match up.

Neck Size Matching

It’s simple to match a dispensing pump neck size to a bottleneck. For example, if you take a 24/410 neck size; you need to match that code with the same 24/410 bottleneck. Once you match each dispensing pump to the desired bottle design, we recommend ordering some samples so you can fit them together. From this process, you can eliminate what works and what doesn’t. This mix and match strategy gives you more control over the product’s final design.

    Are these measured in millimetres or centimetres? Also, just wondering, but what effect do the ratios have on pressure and power?

      Hello Rohan Sira,

      We measure in millimetres. The ratio depends on the viscosity of your product. This can effect yh pressure and power of the dispensing effect.

    I need a pump for a ceramic bottle- white with a 3.7 cm mouth diameter. It looks like the 28/400 would be a fit. However, I live in the US and only need 1 pump. Is that something you could provide? I cannot find anything here that fits.
