Hi all,
I'm trying to build a small diaphragm pump suitable for 1-2 years of continuous daily (off-grid) use. Therefore, a brushless DC (BLDC) motor is required. I've extensively looked into what's available from US/Europe/Chinese manufacturers, and it seems that pretty much all of them only offer diaphragm pumps with brush motors (<1,000 hours of expected lifetime). Those offering BLDC motors due so with micro-diaphragm pump heads (<1 liter per minute flow).
I'd like to run a pump like this one ( off a BLDC motor for a max Q of ~12 liters per minute and max pressure of ~45 PSI.
Is there any good reason why a diaphragm pump head like the one included in link above would be incompatible with a BLDC motor with appropriate gearing/power?
Thank you,
Allen
