You are my rock, LB. I have been gone for a month+ and sure enough, within 15 minutes your here helping me out.
I am familiar with all the milking parts but what I am unclear about is how the motor powers suction. Obviously (?) some vacuum in between. From the pulsator onward I am good to go, I just need to understand in between the pulsator and the motor. We are milking just one cow at a time, so 3/4 hp has served us well, although 1/2 is probably sufficient. This setup is for Costa Rica where I presume it will be easier to get a little honda motor than an electric vacuum pump, and the site is off-grid so the gas-powered has some advantages in that way as well.
Oh and uh, whats a CFM?
Thanks again!
