Good point on suspension "beef" Jerry, I have put the timbrems on truck to help resist squat

Seem like you are having trouble embedding video.

Nice, I remember you having that tool at Vegas. The embed is icon

Sounds convenient, do you have it operating via remote?

Thanks Russ J, the 203600600 looks like the one to go with, its probably repairable ?

.....

Tony, whats up? Hope all is well. Darn......The length of time I took to remove that gum I would still be there (2 years later)..... However Tony (calm tone, setting the mood of my thoughts&written word, :) ), I did not use or focus on your machine's use other than when the waterjet sounded super sonic on the stencils. I agree that impact is important for removing gum. 300 degrees and a standard expanding nozzle application used at removing gum at the Vegas Round Table in retrospect was not an optimal method for the gum conditions. (video proves this) You hear.....Jim G, Tom and I was attempting to determine what would speed the process. I really cant tell how many pieces of gum Chris C removed in other video clip (not sure if it was more than one, Chis C could tell us, I know he used both rig guns) but without a shadow of a doubt, I can clearly see that it took some doing for me to remove one piece of dried/rigid gum. Vegas Round was a great experience, because of this I have learned to adjust a number of inputs when performing gum removal. p.s. Jim and I do talk a great deal about pw, my wife looks at the caller id and says "its Mr 300 calling"

I think it is possible that a lower grade trigger(or one that is operated at its upper capacity) in combination with standard lance my produce noticeable losses. I remember the better guns were 13/32" check ball,.......is there any trigger guns with larger than this? Is their a high pressure trigger gun that has extra large internals and a 3/8" outlet?

Dropping down 1 more size means what Russ J? Which would draw more, drop down one more size with his 300ft set up or current injector after 100ft?

Sounds nice any pics? True Paul , its high flow pw's and some commercial sites is where I have had problems. It would get the job done. Nice idea Is that 4.2 gpm a hot water?,,,, just attempting to figure the weight of the unit and the space it may occupy in the van. Its not the houses that have water its the ones that have but the outdoor spigot cannot keep up. But I think you should be fine most times, but if you have the bigger tank and the space , when you get the commercial jobs you would not have to re-arrange the van immediately. story/experience: went to do a residential and turned on the spigot for about 3 to 5 seconds had good pressure and flow, bleed the fill hose of air saw water exit the hose before connecting directly to the cold unit , started the machine and within seconds the pw pump sucked all the water out of 75 feet of 3/4" fill hose, I was at the end of the wand thinking "what the" .....; ...there was no water in spigot, it was the residual pressure in the house lines that flowed initially and somewhat filled the inlet line. After that incident the "cat 5cp" had seven lives left

LOL I guess I did not read Jim's post in its entirety, my error.

Got pics of the trucks Ed, sounds sweet!!, Jim always mentions about the rigidity of the emission laws in Ca . I think that is one of the reasons why he upgrade his pressure washing power plant a few years ago because he knew of some upcoming laws that would have meant additional investment for a leaner emissions motor.

Depends.....Like Ed suggest bigger has its advantages,..... if you have a 150 tank capacity, you can fill it to 100 gals but you cant fill 100 gal tank to 150 gal. What gpm machine are you using? What type of washing will you be doing? Does most of your jobs have available water supply?

I have only one input thus far, Sioux, have not heard for another forum in which I posted, I guess I would have to go back to school for this one.

What type of van are we talking about 1/2, 3/4, or 1 tonne. I can be done but as with everything there would be a limiting factor, in this case the max GVW of the vehicle. What size of tank you were thinking, remember water ways about 8.33lbs per gallon.

Most do shop price,...... I have read about the splash lube limitations and general pump has a min on some pumps of 500 rpm. Thanks Russ J.

What type of material is used for the plungers on UHP pumps? I knew of the disadvantages of having high speed (3400 rpm) pressure pumps for commercial cleaning and the advantages of 1750 and 1450 rpm speeds, but as I read more on manufacturers websites I noticed that the industrial units use even lower rpm pumps or they are oversized pumps, so that the installer can lower the rpm to achieve the desired flow. Russ I dont know of any commercial hot water units from the big brand manufacturers that oversizes or have the option to oversize the pumps on their units, is there any? I wonder how much more life/less maintenance maybe gained by reducing speed from 1750rpm to say 1000-800 rpm.

Via a dealer, who gets it from Spraymart.

Thanks Russ J. I noticed the US General Pumps did not alter the max pressure rating on the 66 series TSF's (only a few models bumped by a few psi). It is interesting however that they upped the max pressure on the TS2021 units in the US, I guess the engineering dept. figured it could be done without safety and pump life issue, and more so the need to have a product to compete in the popular market segment. The new 4350 psi max rated pumps in the 66series class may also be a product produced to fill a market segment. I wish however there was a more affordable 8 to 9 gpm factory max pressure(4300 to 4500 psi range) pump on the market. I have set my TSF2021 above max rating once and the additional 600 psi increased speed at the end of 200 feet of hose, especially in the surface cleaner. I remember reading that one of the key factors in facilitating an increase in the max pump rating is the diameter of the plunger because of the "forces" acting on it. (Usually smaller bore pumps in the same series of pumps are rated at higher pressures, even more so when the speed is reduced). I guess if I had to build a rig today I would use a dual over sized pump setup to achieve the higher flow at at over 4000 psi rating I desire, this would provide a much lower cost than the General Pump "KE series" pumps performance I so long for.

Russ, whats the scoop with the different pressure ratings on the 47 series pumps between Italian Interpump (1450 psi max) and US General pump(3500 psi max) for the same speed and gpm in the series? Are the pumps mechanically identical?

After Looking around on the net at this pump, I noticed that Karcher company has their hands on almost everything pressure washing/cleaning, they own Landa, Spraymart (dealer pw superstore) and the Legacy brand.

Russ J,........ whats the scoop on this pump GT5635 Why would general make a pump HP5535 to compete against their own product TS2021 ............is it a North American manufacturing issue? Similar to Honda Japan and Honda USA

It probably has to do with the orifice size being suited for your pw machines vs a 1/4" hose barb and the fact the flow through it is more streamlined. The manufactured nozzle is a precision tool the hose barb is not, not bashing the use of a hose barb, I use it. But am writing this to say that two 1/4 inch hose bars from the same manufacturer probably would have greater size variation than two pressure washing zero tips from different manufacturers.

I would like everyone to know that I am individual that likes to understand a the Engineering Function and Design some mechanical systems. In this thread/discussion this is what I am attempting to understand (like the few other threads I have started). Here we go. I would love to see the "Stone Rider" as well Scott, it is not a matter of you proving to the rest of us what equipment you have, but to understand how this piece of equipment has helped you and your company achieve garage cleaning success. I have seen a couple weeks ago a brushless hard surface cleaning rider capable of filtration on the go that could revolutionize large area hard surface cleaning (not the cyclone). Even Kathy at Parker West has a new larger sized rider developed. Its the way bigger pw companies are headed. Ron," what is the right pressure combo water volume", it depends on a great deal of factors: As I have learned from these boards, and put into some practice , it depends on what you are cleaning, if filtration is required, end use tool/technique needed, budget and some other items I may have not included. Scott, I like the "pressure cooker" analogy it has some factors that can be referenced in our application but it has one factor that is not occurring in the boiler and hose of a pw system. The air space in the "pressure cooker" the pw boiler and hose does not have an air space. But anyway lets break it down: Heat is supplied to the "pressure cooker", the heat energy is transfered to the cooker and the water, the water molecules become excited and then break the the surface the water, the air space above the cooker is now being filled with water vapor, the water vapor now has no where to go (because the cooker is closed and the weight is on the nozzle) the pressure is now increasing as more vapor is released from the liquid into the space above it. This is where we use science to advance man, a property of water is;..... as the pressure is increased on/over water (and heat is continued to be supplied ) this action raises the "normal" boiling point of water beyond 212F. ("normal" being the boiling temp at atmospheric pressure, 14.7 psi) The engineers of the "pressure cooker" have come up with a safe working pressure based on the a number of factors, there is a zero degree nozzle on the dome of the pressure cooker, a weight is designed to fit over the nozzle to block the orifice, when the pressure builds to a particular level the weight is tilted or slightly lifted and releases some pressure until it re-seats on the nozzle. The better pressure cookers raises the pressure in the cooker to about 15 psi above "normal" which would allow man to boil water at approximately 252F, hence allowing us to cook (breakdown) food (organics) faster. (in the pressure cooker two phases of water exist : liquid and vapor) Now look at the similarities of what is occurring in the pw boiler and hose. The burner supplies the heat to the coil, the coil heats up and transfers its heat to the water (but there is no space of air in the coil or the hose after it is filled) the pressure in the pw is way beyond the cooker anywhere between 2000 to 4000 psi so this means that we can also take advantage of the properties of water and heat it above 212F. Think about this: What would happen if we filled the pressure cooker continuously with water from a pressure pump capable of 6 gpm at 3500 psi so that there is no air space in the pressure cooker it is always full of water while it is still being heated by the stove, the pressure cooker cover nozzle has no weight on it so water escapes from the pressure cooker as soon as is is pushed through the pressure cooker via the pump , as the stove heats the water in the pressure cooker the temp rises, the pressure in the cooker would be dependent on the size of the nozzle in the pressure cooker cover, nevertheless the water would be able to increase beyond the "normal" boiling temp of 212F because the pressure would be higher than "normal" (atmospheric), ....... lets say we get it to 300F, what is happening at the pressure cooker nozzle now? Is it all steam? We know it would be all steam in a regular pressure cooker because there is no water directly under the cover of the pressure cooker nozzle only water vapor. We have to turn to science again to tell use what behavior is exhibited outside the nozzle in pressure cooker with pump scenario. This is what we know, the pressure outside the nozzle is "normal" atmospheric pressure, and that water in the pressure cooker cannot be created nor destroyed, so that means the water outside the pressure cooker has to be in one of water's forms or a combination of forms. (that is: solid, liquid, vapor or gas) Which is it? So lets say we have a big boiler and we achieve 300F in the pw system, we already know that 252F in the pressure cooker cooks,melts,breakdown,remove oils from meats much faster (up to 1/3 the time), so these high temperatures should do the same for hydrocarbons in the concrete. But how can we get these temperatures (300F) to exist outside in the "normal" atmosphere, what does the properties of water say can this be done? Does this mean that the fluid exiting the zero degree nozzle is 100% steam? What is its temperature? What is the effect on the impact force? I have asked these questions of engineers and awaiting their responses. This is one of the great things about these forums and the internet. Good to hear from you too Ron. I have asked an engineer at Sioux pressure washers yesterday about the 300F and awaiting what other engineers have to say about it and what phases the fluid would be when leaving the nozzle etc. We will all see the answers, if not I will meet with a professor at the local university and ask them to explain what maybe taking place, I want us all to understand. About large filters, I think it up to your budget and how often it would have to be serviced during operation, the bigger it is and the better design the more loading capacity it has. I agree Scott does not express his accomplishments as Jim does, but that just a way they are both different. Jim has shared his experiences with a fire hose use and its advantages and disadvantages and explains this to us and his clients, he and his clients make a decision if its use is warranted on a particular garage. Ron you have given to this industry a great deal in your 25 years and I thank you for this. About Vegas demo cleaning , (dont laugh) I do not recall that Tony's Landa unit offered a superior cleaning over an area in which Jim's unit cleaned. I know that Tony's waterjet surface cleaner worked like a charm on the stencils, but Tony's unit had more difficulty at removing the Vegas baked gum than Jim's unit (Jim never hooked his unit to any surface cleaner). Its a pity that the personal/industry relationships that were built at that round table are dissolved. I learned a great deal thus far, and i am still learning.
