Adapting the standard Brompton pump to be able to pump to high enough PSI for every day use

Hi all

I'm thinking about ways to adapt the Brompton pump to make it usable as a main pump and not just for emergencies. I really like the idea of a low cost, community produced open source designs to allow for different needs.

Issue with the pump

It seems like the main barrier to the Brompton pump being able to pump to higher PSI is that the design means the user can't pump efficiently, rather than the pump isn't strong enough to withstand the higher pressures. The website claims the pump can 'inflate tyres up to 160 psi' https://www.brompton.com/p/597/pump-with-mounting-brackets?Colour=Black

Solution

I'm wondering if it would be possible to add parts to the pump to make it into a kind of mini track pump where you can use you larger muscles, not just your arms to get enough force to produce higher PSI. It seems like there are already many pumps with this kind of design, some have legs, some just have a foot, some have a bar at the top, others just a handle. I think It would be nice if the additional parts were small enough that they can be kept on the bike as well.

Parts

If we break the problem up into pieces we have:

1. Top bar/handle: how to attach the top bar, screwing it into the thread would be one option, or simply sitting on top could be another. Some mini track pumps don't have either of these and just have the barrel like the Brompton pump.

2. Foot or legs: this would need to find some way to protect the tube from the downward force from pumping and also make the pump stable. One additional element could be a pressure guage which woud be useful.

3. Attaching to the bike: I guess these could attach to the pump itself or kept in a pouch or the frame.

Questions

What do people think of this? Do you have ideas?

Does anyone know of any existing projects or parts that could adapted?

Thanks 🙂
