This is a small reciprocating air pump used for various tasks including aerating Koi ponds and providing modest volume air at low pressure continuously. It uses an electromagnet to move a spring loaded piston with a close tolerance ceramic coating, so that no physical seal or wet lubricant is needed on the piston itself. This makes it very easy to move at low power.
This particular pump is one of the smallest at 25W and 45 Litres of air per minute, but others are available with higher ratings up to about 275Lpm from what I can see online.

    nice teardown and analysis. Do you happen to know the pressure limits on this pump? certainly high volume at 0 psi, but will it pump to 1bar or 2bar?

    How do you know when you would have to replace the diaphragm besides the obvious signs of damage? Would you replace after a certain time frame?
    Thanks

    Do you still have it? What happens if you run it, or one of the little solenoid pumps, from a VFD? Is the spring/mass tuned to 50Hz?

    why such small intake holes? could it help performance if these were enlarged?

    excuse my stupid question. Can you use this to build a mini refrigiration system?

    I have an ACO that got extremely loud and stopped putting out air. It appears to be the Guide Shaft that I need. Any ideas?

    Does it have inbuilt NRV (non return valve) system
