Does a TSF 2021 pump need two belts??

I have a TSF2021 8.5gpm @ 3600 psi pump. I'm adding a Generator head to this Powerwasher since the engine is a Kohler 34hp which has plenty of extra HP. So I have a couple of quick questions concerning this and I added a couple of pics to see what I'm trying to do.

The Generator needs a pulley to be the same size as the one on the Engine so its a 1-1 ratio so the Generator can spin at the required 3600 RPMs the engine shaft is spinning at.

So here's the questions: Can I take one of those belts off the Pump so I can use that outside groove in the engine pully for a belt to go around the Generator Pulley? Does the pump really need those two belts?

The last question is if the Pump needs that extra belt can I just add a single pulley to the 2 groove Pulley thats already on the engine shaft to be used for the Generator or do I have to remove that Two groove Pulley and replace it with a 3 groove pulley?

Heck yeah it needs 2 belts! At least as far as I know, there must be a spec on horsepower / v-belts. If it's running 8,5 at 3000 or better, I think it should have 3 belts! If another pulley fits I don't know why you couldn't use it but a triple pulley sounds better.
 
Absolutely. 3 belts would be recommended.
 
Can it be done, yes, but I would recommend putting on the widest diameter pully's possible if doing it. The more surface area the belt goes around the less belt slipping you will have. I run two tsf2021's off of one engine with only a double pulley on the engine and one belt per pump. I don't run 3600 psi, but I keep it between 2500-2700 psi most times with no slip. I am not even running the slotted belts yet as I am waiting for the standard belts to wear out first.

Since it looks like you can't increase the diameter too much I would just go with the triple and make life easier. Easiest solution is a small inverter generator for the 120v which I am assuming is to run your burner. I have a little champion 1600 watt one from costco that runs it and sips little in terms of gas. Its way cheaper to run the inverter for the burner and only have to run the PW 35 hp engine I have at 2200 rpm then it would be to run the PW at full power all the time. The inverter can run a day and a half on the fuel that I burn in an hour with the 35 hp engine going full tilt.
 
What is the difference between a regular generator and an inverter generator?

I don't think I have seen one of those out there.

How much do those cost?

This is very interesting, I need to replace a generator on a Landa machine but this inverter generator is not a bad idea.

I looked up your question and this is the answer http://wiki.answers.com/Q/Difference_between_an_inverter_generator_and_a_generator

The generator head is what most powerwashers have that are 120 volts. You have to have enough left over HP on the engine to run an extra belt or two so you don't loose out with your pump output.

I'm putting a 5000 watt generator head in there and it takes on average 2hp to run 1000 watts maybe a little less. That generator will fire up two burner when in operation. What we been using was a cheap Generator I had for years that is rated at 3500 watts with a 3000 watt surge.

The problem we where having was when both burner kicked on the same time. When running they operate from what Russ Johnson and other told me about 600 watts. It takes about 1800 watts to fire them up... my Generator isnt strong enough at this point and one of the burners seem to get screwed up a little do to the lack of start up wattage... and where burning gas on a seperate engine.

I expect the powerwasher to burn a little more gas when the generater head is in use but since the pump already is running off of the 34hp Kohler I would expect that will burn less gas then also using a stand alone generator and the space saver on that alone is huge... Now if I can get a 3 groove pulley this week from Granger(They have everything when it comes to this type stuff) this generator will be up and running very soon
 
First I must apologize, I have the TS, not the TSF version of the general pump. There is a big difference in power requirements to run the two pumps and of course I had the lower powered version specs in my head. In terms of belts though if you can fit a triple go for it as it will be your easiest option

Here is a version of the inverter that I am using

For some odd reason Costco here in Canada it is $200 cheaper for what looks to be the same Inverter. That price on Costco is the delivered price, in the local costco it's $499.

Only difference is the 12v outlet I think on the northern tool one, but the wattage is pretty much the same.

I am running only one Ironhorse 880,00 btu burner, but I run it full tilt to start the burner then throw it on eco mode after the big start up drain and let it be. I do run it 12 hours while in eco mode on one tank of fuel.

One other advantage of the inverter is if you have a small microwave you can cook or reheat lunch in the field no problems. I do have a microwave in the cab of the truck and this is an awesome feature when you have to be on site all day and can't leave (Curse of being able to carry 2100 gallons).

If space is your biggest concern go for the generator head and the triple pulley. If you have a little space I would look at separating the washer and the generating side if possible. You have more flexibility to lower the rpm to save fuel when you are not using the full GPM/PSI that you can make. With the generator head you need to run full tilt to have things work properly all the time if you plan on using the burner.

Good luck either way and let us know how things turn out.
 
Hey Benjamine space is an issue with this truck which is why I'm popping in the generator head.All our Powerwashers run full speed all the time and if we need lower PSI we just change out the tips so the engine can keep running at its operating speed which is full tilt.
As for the generator the pulley from that to engine must be 1-1 ratio. I let you know how this works out.
 
The microwave is a great idea, so many times stuck on a job or out in the middle of nowhere, it would be easy to take something to eat in the ice chest and warm it up in the microwave.

I wonder if you could use an inverter, maybe 2000 watts for a microwave or other small electric tools like drills and grinders for short periods and have the marine battery connected to the truck charging system to charge the battery when driving?

Anyone try this with an additional battery for use with a large inverter?
 
I run an inverter off the truck for backup, so only when I run out of gas in the generator or something stupid happens and it stops working. 3000 watt inverter and I run 4 #2 welding cables right to the batteries. The inverter had 2 positives and 2 negatives, figured I had better hook it up right and since I have 3 group 31 batteries on the truck I just used the 2 closest to the frame. Just a note the cables are expensive, I got the inverter on sale and the cables to hook it up cost as much as the inverter in the end.

If you want to separate the batteries (IE Truck then another set for the inverter) I would highly recommend using one of these.

Just also remember if you don't use a pure sine wave inverter the microwave will need something else running for it to work. I don't have a pure sine inverter and have to run the burner or a sump I have on the truck at the same time for the microwave to work. If I don't run something else the microwave turns off a few seconds into cooking. The pure sine wave will eliminate that, but they are big expensive. Don't make my mistake either and get a 1200 watt Panasonic microwave, it says 1200 watts, but I think its closer to 2000 watts that it needs to cook. Get as small of a microwave as you can power wise, don't make the same mistake I made.

One other thing, most times for a good size inverter you need two batteries as one just won't hold. Personally just hook it up to the truck and run the truck when you need to run the inverter. The extra batteries will cost a good chunk of money and the weight and size are a real pain. The amount of fuel needed to idle the truck for lunch or to quickly run the tools is minimal compared to the battery cost. Just saying
 
Thanks for the info Benjamin. Definately things to think about.
