Hi, I am building a vacuum robot and was looking for a relatively quiet vacuum pump for the fourth stage that sucks the dirt and pet hair up and transfers it to a holding tank. I have searched google but all of them are really loud. Thanks
quiet vacuum pump
Never heard of one.
Use tape.
Are you sure the device you need is a vacuum pump.
I've not heard if a cleaner that uses a vacuum pump. These devices are only normally used by people installing air conditioning systems to remove air and create a partial vacuum in the transfer tubes.
You just require a fan and motor, probably a turbine fan etc
But as Larry says, I doubt a very quiet device of this sort exists
You could look at using electronic motors from radio control aircraft, they are powerful and not especially noisy, however as soon as you couple it to a fan or turbine the movement of air etc is bound to be noisy.
Also consider static electricity pickup , but that would require some sort if conveyer system etc
