Anyone, using motor for generator and pump?

Hey guys I recently took this heater and cage in trade for some things sitting around unused in my garage.

My question is, does anyone here drive a generator and pump with the same motor? What HP motor for say a 5.5gpm pump? If so where to get the pulleys? How is it all wired for you? To feed this thing with water does it need to be mounted at a lower height than the buffer tank?

And I am sure there are other questions, but that is it on the top of my head.

Motor running a pump and generator is a standard skid set up. A 5-6 gpm machine usually has a 16-18 hp motor. A triple groove pulley on the engine with two belts one way to the pump and one the other way to generator. If you google around brands and suppliers you will find a lot of pictures. I get pulleys local at the bearing-belt-type store. Lower than the water is best for a pump but a belt drive will lift water.
 
It might be cheaper, faster and more efficient to just ship it to Russ at Southside Equipment and have him build you the rest of the skid.
 
Give me a call. I can get whatever you need to rebuild it and help you over the sticky spots too.
 
Keep in mind also, if you plan on using a Honda engine with it I'd recommend going with at least a 20HP. Great engines but they don't typically produce the HP they're advertised at compared to other manufactures. One of my skids that has a TS2021 (5.6 GPM/3500 PSI) w/ generator has a 24HP Honda powering it.
 
One other piece of advise. Make sure you get a fixed position throttle engine with it. Because it's running a generator it has to turn a constant RPM to generate the correct voltage / hz. Otherwise you run the risk of burning up whatever is plugged into that generator.
 
I have found the hondas run like nothing else, quiet and smooth. The gx690 will run 10 gallons at 3000 or 8.5 gal at 3500 - regardless of what horsepower they are supposed to be. I would look at what pumps the manufacturers put them with and use that as a guide.
 
Started to post this in the Facebook page but remembered this thread was started. Russ I applied to potentially buy a unit from you...I am thinking its getting a bit too busy and hopefully more so next year to be attempting to build a unit myself and all the learning that comes with it. It's one thing to fix a car, it's another to build it from scratch.

All of this to say, what do you think that stripped unit up top would bring? Thinking about listing it locally.
 
Good info in this thread! I don't mean to hijack, can someone very vaguely explain this quote below? I only ask because I notice my belt drive has a lot less effort in getting its water, when I mentioned this at a place outside of town I needed fittings from I was laughed at. I'd like to know for myself, or have the option to be snoody to future people like this.

For whatever reasons, and I think it's slower speed and larger, longer 'cylinders', a belt drive pump will suck water uphill where direct drive pump that runs at 3600 doesn't

Exactly why. The length of stroke isn't nearly as important as diameter. For instance, a 4 gpm direct drive, I'll recommend an AR RKV over a Comet ZWD or General EZ every time. The RKV has an 18 mm bore and 7 mm stroke, while the other 2 have a 13 mm bore and 13 mm stroke. The shorter stroke actually takes less time to flood the cylinder than a deep stroke, and creates a better vacuum.
 
Hey Russ, you are the man. I was thinking of your explanation but would never be able to put it into words. You even came up with numbers to back it up. They could be BS numbers (though I'm sure with you they are not) and I would still be impressed. good job.

Was a mistake from my first days, apparently I haven't thought that section valuable enough to proofread and fix it, so thank you...noted and fixed.
