Building fire pump selection?
I’m overseeing a building refit and we’ll need to install a fire pump. Most are recommending an electric pump, but that implies a much larger electric generator (100 kVA more). Also, we hadn’t planned a generator in this first phase of the project.
Can anyone tell me what my other options are?? What about a diesel pump? Or a small temporary generator for phase I until the other phases are complete?
A 500 GPM, 100 psi pump will pull 55 horsepower and can be electric or Diesel. That flow will operate two standard 2 1/2" fire hoses. If you need the pump for a sprinkler system, that is another matter.
The National Fire Protection Association (NFPA) and Underwriters Labs. (UL) have fire protection criteria and standards for certification of special purpose fire pumps. Also check with your insurance carrier.
I suppose that you do have a source of water adequate to pump 500 GPM for an hour.

want to build an electric generator from an electric motor, how do I do this?
I want to build an electric generator from an electric motor, how do I do this?
I need planes on how to build a generator from an electric motor. I am wanted to use a 16 HP Power Diesel tractor motor. Can any one help?
I am useing Diesel power because diesel fuel last longer than gas when in storage. Is this correct?
I want a AC Generator.
Very simple. You need an electric motor of the same wattage as you need to generate. You will need to spin the motor a little faster than the rated RPM of the motor. (pick your pulleys carefully) Hook a small load up to the motor, spin it, hit it with a jolt of voltage. (try your 12 volt battery)It should start to generate and you can hook up a bigger load to it. Too simple? Try it.

Why do my lights flicker with my portable generator?
I live in southern Indiana, and am currently living through an awesome ice storm. Anyway, my parents bought a diesel powered portable generator. It is hooked into the main panel of the house. When you crank it up and turn the lights in the house on, they flicker, as does the TV screen. It has proper voltage on each leg of the 240. I brought my generator over and everything works fine. Any ideas?
It is an All Power Diesel 6700 watt generator. Should be about 6500 watts more than I need to keep two 100 watt light bulbs burning strong!
Runs strong, with no stalling or hiccups.
Its an All-power 6500 watt air cooled diesel generator.
if you hooked another generator to your panel and it worked fine the new generator is the problem. unless you changed the way you hooked it up. in that case look at your connections, closely at the ground for sure
