I have looked at one. Didn't see a demo, but have heard they are tough lil pumps. Numbers are not that impressive imho.

That price is almost exactly double what they quoted me...same setup with hose etc.

Need twice the gpm at least for me to consider a pump. I'm tired of 4-5 gpm. Want about twice:/ I'm sure you will hear tons of advice but the man that showed me that pump has been my rock as far as eqpt/advice. I told him I was looking at that and a JB "chloro" pump...
He said hands down that is better as far as lasting longer(worked with both). He said the parts for that pump are cheap and very very easy to switch out. He would have gave me a 1 yr wtty I think it was.

I have my sites on a pump/motor and its not one I mentioned.

Here's the one I just bought...

Delavan 5.3 gpm @ 60psi..



Haven't hooked it up yet but I pulled my 1.8 gpm Shurflo off and put them side by side for you guys to see. What have you heard Don?

I personally think they are the new, pump of choice, for an entry level roof cleaner.

One of these, with 5/8 hose no longer then 200 feet should make one a decent living.

Though the outlet ports are 1/2 inch, at 60 PSI 200 plus feet of even 1/2 inch hose will limit you a bit.

The more flow a pump delivers, the more important hose size becomes.
At lower flow rates, hose size is not as important a consideration.

2 of these in tandem should be an awesome, inexpensive alternative to some more expensive pumps.

Let us know how it works out.
I think it will beat the shurflo myself

So far, this pump is keeping me off of un-walkable roofs. It will shoot about the same distance as the 1.8 gpm shurflo was but with a more substantial stream.

With the 1.8 shurflo, I was using a 0010 tip to shoot and it was very light and at the mercy of wind. Now, the 5.3 GPM Delavan... I shoot with a 0040 tip and it soaks the area quicker and is a more "Durable" stream. I can hoot outward (horizontally) 30+ feet. Shooting higher is another question though. I still think I could easily clean some vinyl sided homes with this thing.

Performance wise, it is doing what I wanted. Longevity will be the real test. But at $129, It can last 10 roofs and still be a good throw away expense that is simply factored into the pricing of roofs. Used it to clean a 2000 sqft 4:12 pitch roof the other day. 45 minutes= $375 not too bad. I keep raising my price... I still don't know what this market will bear.

I don't much care for the GC engine on a machine that will be subject to daily use. Don't get me wrong, the GC is a great engine in proper application. However, these engines are targeted for consumer use, not commercial / industrial. The GX would be a much better choice for heavy duty users. The biggest thing to remember about the GC is oil changing. These engines have a teflon coated piston in an aluminum cylinder, which works wonderfully as long as the lubrication is right. Grit in the oil will scarify the teflon off the surface, then you've got aluminum / aluminum contact...not a good thing.

Checking the site, I see it's offered with the GX...worth the extra $$.

As I mentioned here previously and on Wednesday at the TGS roof chat, I've seen these pumps in a local shop. We've never tried one, but as Russ mentioned, the motor isn't a commercial grade unit and the gas tank is somewhat small. That probably doesn't mean as much to some if it's used for residential only, but it would be an inconvenience on larger, all day jobs.

Also as previously mentioned, the good things are the plastic tank and starter rope coil cover.

Time will tell if the motor or Comet pump will hold up. Personally, I'm skeptical.

We have this pump. Once the pressure is set for your speed and tastes, It stays pretty good, We have had to replace a lot of manifolds. They have cracked from pressure, NOT chemical. The sales rep at comet ack. that there was an "issue" with the mold. (knock on wood) the current manifold we have had on for 6+ weeks.
The nice thing is that I can repair the entire pump on-site. ( and have )

The GX would be a much better choice for heavy duty users.

We have a 4.0 HP GX. It can run for 2 days on one tank.

With this pump you run it barely above idle. It is great on gas!:thumbup:

Hey David,

Hope you guys had a good Christmas. I haven't been around too much lately. Just enjoying the time off with our family and friends.

We've got some nice things cookin' for '07 and will probably give this pump a spin for the heck of it to see how she compares to the JBs.

Happy New Year!
Don

Back at Ya!! I would not waste the $$ on this if you have a JB, Our next upgrade will be either the UDOR or a new one from Comet.

We had to learn the HARD way that Polyproplyne is NOT "forever" with Chlorine.

Our John Blues leaked, manifolds cracked, and EVEN the pumps we NOW use finally started biting it.

The Cole Parmer Chemical Compatability Database SHOWS Polyproplyne as having an "A" rating against Chlorine's harmful effects.

But, in practice it does not.

WHY ?

Because every manufacturer uses GLASS Filled Poly, to strengthen it against the Pressure.

What is really need is KYNAR.

Our NEW pump is made out of KYNAR, with Teflon diapraghms and ball valves.

You live, you learn.

IMHO, between a Comet and John Blue, I would take the John Blue hands down.

WHY ?

Because John Blue listened to me what I contacted them in Italy!

I suggested Hastelloy springs, valves, and retainers.

They were scared it would push the price way up, and it would not sell.

Instead, they made the check valves EASY to change!

the ultimate washer

I was just talking about gas powered application in another thread. That machine is great. Get a good price, because they do vary. But the machine itself is an excellent chem applicator. ANY electric machine is a chance. Sometimes they're ok, sometimes they're not. Some people have never had a problem with elec motors, others have had nothing BUT problems (I'd imagine that's because some people know how to take care of the elec motor, and some people dont...BUT), and there's other people who are like me... who FLUSH continuosly after use, and STILL run into problems with about SIXTY percent of electric application systems. I'd go with that gas powered...it's a great applicator.

When looking at electric, look for TEFC motors.
TEFC means totally enclosed fan cooled.

We do not care for electric motors, unless a generator is also carried.

Many places we do do not have powwer.
