Delaval 75 motor size
I have a delaval 75 vac. pump and I was wondering what size motors you guys run on them hp and rpm wise. I has a 1.5hp motor 750rpm on it now but I was wondering if I could get away with a smaller motor the location I want to put this has only 30amp service and I would like a motor that would draw a few less amps if possible
Thanks Jeff

If you go with a smaller motor you will need to decrease the speed of the vac. pump by changing the pulleys. It will decrease the CFM's but otherwise your smaller motor will be overloaded and burn out.
Actually a 1.5 hp is small for most vacuum pumps in the maple business Keith

You say you have 30 amp service so that is 60 amp available right? if you have the power why noy switch it to the 220 side of the motor and it will run alot cheaper. I think 1hp to 1 1/2 is fine. Remember cfms are nice but a good tight system is better. Every leak is a bacteria laden airator that will lead you down a path of ****ation.

Switching a motor from 110 to 220 doesn't make it cheaper to run. It does leave more amps available in your service for other things though. The voltage times the amperage gives you how many watts it will use. Your electric bill is figured using watts or kilowatts. A motor wired for 110 volts uses 10 amps equaling 1100 watts. The same motor wired for 220 volts uses 5 amps equaling 1100 watts.
If it isn't wired for 220 volts already it would be a good idea to do it to cut down on the amperage used. If you have a 30 amp circuit using 5 amps and having 25 amps left is better than using 10 amps and only having 20 amps left.
